</p><h2><a name="platforms">Platforms, C++ Compilers, and Support</a></h2>

<p>ACE has been ported to a large number of platforms using many different
compilers over the years.
The <a href="http://www.dre.vanderbilt.edu/">DOC group</a>,
<a href="http://www.riverace.com/">Riverace</a>,
<a href="http://www.theaceorb.com/">OCI</a>,
<a href="http://www.remedy.nl/">Remedy IT</a>, and members of the ACE
user community have all contributed ports to make ACE the successful
and far-reaching toolkit it is today.  Any UNIX/POSIX/Windows
variation is probably an easy target platform for ACE.  If you have
<a href="docs/ACE-porting.html">porting questions</a> or have a problem
compiling the ACE source distribution, please contact one of the
commercial support companies, or send a copy of the
<a href="PROBLEM-REPORT-FORM">PROBLEM-REPORT-FORM</a>, located in the
ACE_wrappers directory, to either the <a href="news:comp.soft-sys.ace">ACE
Newsgroup</a> or the <a href="mailto:ace-users@list.isis.vanderbilt.edu">ace-users
mailing list</a>.
The DOC groups at Washington University, UC Irvine, and Vanderbilt
University provide only "best effort" support for non-sponsors for the
latest release, as described in <a href="docs/ACE-bug-process.html">
docs/ACE-bug-process.html</a>.
Thus, if you need more "predictable" help, or help with earlier versions of
ACE, it's recommend that you check out the
<a href="http://www.dre.vanderbilt.edu/support.html">list of
commercial support companies</a> for additional assistance.
</p>
<p>The responsibility for maintaining ACE across the wide range of
supported platforms is divided among a few different groups:
<ul>
<li>The DOC group maintains platforms used in the course of their research
and sponsored work</li>
<li>Companies that provide support (Riverace, OCI, and Remedy IT), maintain
platforms they support in the course of their various service offerings</li>
<li>The ACE user community maintains any other desired platforms.</li>
</ul>
The <a href="http://www.dre.vanderbilt.edu/scoreboard/" target="_blank">
build scoreboard</a>
records the current status of build and regression testing during
development by all of the above groups. It is available to all users wishing
to provide build results. Members of the ACE community that maintain ACE on
platforms not maintained by the DOC group, Riverace, OCI, or Remedy IT are
encouraged to provide build and regression test results for the scoreboard
to ensure that all in-use platforms are represented.
See the <a href="https://raw.githubusercontent.com/DOCGroup/autobuild/master/README" target="_blank">autobuild README</a> for more information about
how to set up a build; contact one of the above groups to inquire about how
to get your build results recorded on the scoreboard.</p>
<p>Because older
platforms that are not maintained tend to fall into a broken state and
clutter the ACE sources with code that is no longer used, the development
team reserves the right to remove ACE configuration files and source code
specific to inactive platform configurations that are not
listed on the scoreboard.</p>
<p>The table below summarizes each group's role and where you can get more
detailed information.  For information on TAO's platform coverage and
support, please also see <a href="TAO/TAO-INSTALL.html">TAO's install
document</a>.</p><p>

</p><p>Although the DOC group has provided outstanding support for ACE
over the years, ACE's success has greatly increased the amount of
effort required to keep up with its maintenance, answer users'
questions, and give design guidance. Riverace offers world-class
commercial services to support ACE users.  OCI, PrismTech, and Remedy
offer similar services for TAO, allowing the DOC group's primary focus
to shift back to their main goal: <em>research</em>. The DOC group is
fundamentally focused on (and <a
href="http://www.cs.wustl.edu/%7Eschmidt/resume-grants.html">funded
by</a>) advanced R&amp;D projects. The group continues to be
intimately involved in ACE+TAO development and maintenance, but with
revised priorities for maintenance. The <a
href="docs/ACE-bug-process.html">bug
fixing policies</a> followed by the DOC group are designed to strike a
balance between their many <a
href="http://www.cs.wustl.edu/%7Eschmidt/research.html">research
projects</a> and their commitment to the ACE+TAO <a
href="http://www.cs.wustl.edu/%7Eschmidt/ACE-users.html">user
community</a>.  Naturally, we will be happy to accept well-tested
patches from the ACE+TAO user community for any platforms that aren't
supported by the DOC group, Riverace, OCI or Remedy IT. </p><p>

</p><p></p><hr><p>
</p><h2><a name="installpre">Installation prerequisites</a></h2>

<p> ACE (as well as TAO and CIAO) use <A
HREF="http://downloads.ociweb.com/MPC/docs/html/MakeProjectCreator.html">MPC</A>
(MakeProjectCreator) to generate files used by all supported build
tools (such as GNUmakefiles for UNIX based platforms, sln and vcproj
files for VC71/VC8 and Embarcadero makefiles) on various platforms. To
help new users to bootstrap quickly the release bundles of ACE (as
well as TAO) include all needed files to use the build
instructions in this document.

</p>
<p>
If it is necessary to generate
files for build tools for other compilers, one must
run MPC to generate the
appropriate files.  Please see <a href="MPC/docs/USAGE">USAGE</a>, <a
href="MPC/docs/README">README</a>, and <a
href="bin/MakeProjectCreator/README">README for ACE</a> files for
details. The options that have been used to generate the above build
files can be found in <a
href="bin/MakeProjectCreator/config/global.features">
global.features</a> file.

<h2>General Rules</h2>
<ul>
  <li><p>Many features in ACE can be modified by defining some macros in
      <code>$ACE_ROOT/ace/config.h</code>.  These macros should
      <em><b>always</b></em> appear <em><b>before</b></em> including
      your platform specific config file.</p>
  </li><li><p>However, if you want to undefine/redefine macros defined in the
      platform specific config file, these <code>#undef</code> should
      come <em><b>after</b></em> the config file.</p>
  </li><li> If you're planning to build ACE on multiple platforms, you may
      want to consider <a href="#cloning">cloning the source tree</a>

<h2><a name="unix">Building and Installing ACE on UNIX</a></h2>

As of ACE 6.0.6, you can building ACE on
UNIX with:
<ol>
  <li><a href="#unix_traditional">Traditional ACE/GNU Make Configuration</a></li>
</ol>
The <a href="#win32">build process for Windows</a> is different from
the UNIX methods.

<h3><a name="unix_traditional">Using the Traditional ACE/GNU Configuration</a></h3>
<p>
Here's what you need to do to build ACE using GNU Make and ACE's traditional
per-platform configuration method:</p>

<ol>
  <li>Install <a href="http://ftp.gnu.org/pub/gnu/make/">GNU make</a>
      3.79.1 or greater on your system (available via <code>http</code>
      anonymous <code>ftp</code> from <code>ftp.gnu.org</code> in the
      <code>pub/gnu/make/</code> directory).
      You <em>must</em> use GNU make when using ACE's traditional
      per-platform configuration method or ACE won't compile.
  </li>
  <li>Add an environment variable called ACE_ROOT that contains the
      name of the root of the directory where you keep the ACE wrapper
      source tree.  The ACE recursive Makefile scheme needs this information.
      There are several ways to set the ACE_ROOT variable.  For example:
      <blockquote>
      TSCH/CSH:
      <code>setenv ACE_ROOT /home/cs/faculty/schmidt/ACE_wrappers</code>
      </blockquote>
      <blockquote>
      BASH or Bourne Shell:
      <code>export ACE_ROOT=/home/cs/faculty/schmidt/ACE_wrappers
      </code>
      </blockquote>
      <p>
      If you're building a number of versions of ACE, however, (e.g., for
      different OS platforms or for different releases of ACE) you might use
      the following approach (assuming TCSH/CSH):
      <blockquote>
      <code>setenv ACE_ROOT $cwd</code>
      </blockquote>
  </li>
  <li>Create a configuration file, <code>$ACE_ROOT/ace/config.h</code>,
      that includes the appropriate platform/compiler-specific
      header configurations from the ACE source directory. For example:
<blockquote><code>
#include "ace/config-linux.h"
</code></blockquote>
      The platform/compiler-specific configuration file
      contains the #defines that are used throughout ACE to indicate
      which features your system supports. See the
      <code>$ACE_ROOT/ace/README</code> file for a description of these
      macro settings. If you desire to add some site-specific or build-specific
      changes, you can add them to your config.h file; place them
      <strong>before</strong> the inclusion of the platform-specific
      header file.
      <p>
      There are config files for most versions of UNIX.  If there
      isn't a version of this file that matches your
      platform/compiler, you'll need to make one.  Please send email
      to the <a href="mailto:ace-users@list.isis.vanderbilt.edu">ace-users</a> list
      if you get it working so it can be added to the master ACE
      release.</p>
  </li>

  <li>Create a build configuration file,
      <code>$ACE_ROOT/include/makeinclude/platform_macros.GNU</code>,
      that contains the appropriate platform/compiler-specific
      Makefile configurations, e.g.,
<blockquote><code>
include $(ACE_ROOT)/include/makeinclude/platform_linux.GNU
</code></blockquote>
      This file contains the compiler and Makefile directives that are
      platform/compiler-specific. If you'd like to add make options, you
      can add them before including the platform-specific configuration.<p>
      NOTE! There really is not a # character before 'include' in the
      platform_macros.GNU file. # is a comment character.
  </li>
  <li>If you wish to install ACE (using &quot;make install&quot;), set the
      installation prefix in platform_macros.GNU.
<blockquote><code>
INSTALL_PREFIX = /usr/local
</code></blockquote>
      Headers will be installed to $INSTALL_PREFIX/include, executables to
      $INSTALL_PREFIX/bin, documentation and build system files to
      $INSTALL_PREFIX/share and libraries to $INSTALL_PREFIX/lib.  The library
      directory can be customized by setting INSTALL_LIB (for example,
      INSTALL_LIB=lib64).  With INSTALL_PREFIX set, RPATH will be enabled for
      all executables and shared libraries.  To disable RPATH (for example,
      if $INSTALL_PREFIX/$INSTALL_LIB is already a system-known location for
      shared libraries such as those listed in /etc/ld.so.conf), set the make
      macro install_rpath to 0 by adding install_rpath=0 to platform_macros.GNU.
  </li>
  <li>Note that because ACE builds shared libraries, you'll need to set
      LD_LIBRARY_PATH (or equivalent for your platform) to the directory
      where binary version of the ACE library is built into. For example,
      you probably want to do something like the following:
      <blockquote>
      <code>% setenv LD_LIBRARY_PATH $ACE_ROOT/lib:$LD_LIBRARY_PATH</code></blockquote>
      </blockquote>
      or
      <blockquote>
      <code>% export LD_LIBRARY_PATH=$ACE_ROOT/lib:$LD_LIBRARY_PATH</code></blockquote>
      </blockquote>
  </li>
  <li>When all this is done, hopefully all you'll need to do is type:
      <blockquote>
      <code>% make</code></blockquote>
      at the ACE_ROOT directory.  This will build the ACE
      library, tests, the examples, and the sample applications.
      Building the entire ACE release can take a long time and consume
      lots of disk space, however.  Therefore, you might consider
      cd'ing into the <code>$ACE_ROOT/ace</code> directory and
      running <code>make</code> there to build just the ACE library.
      As a sanity check, you might also want to build and run the
      automated <a href="tests/README">"one-button" tests</a> in
      <code>$ACE_ROOT/tests</code>. Finally, if you're also
      planning on building <a href="http://www.cs.wustl.edu/%7Eschmidt/TAO.html">TAO</a>, you
      should build the <a href="http://www.cs.wustl.edu/%7Eschmidt/PDF/gperf.pdf">gperf</a>
      perfect hash function generator application in
      <code>$ACE_ROOT/apps/gperf</code>.
  </li>
  <li>If you've set the INSTALL_PREFIX before building, now run
<blockquote><code>% make install</code></blockquote>
  </li>
  <li>If you need to regenerate the <code>ace/Svc_Conf_y.cpp</code> file,
      you'll need to
      get <a href="http://ftp.gnu.org/pub/gnu/bison/">GNU Bison</a>.
      However, you should rarely, if ever, need to do this.
  </li>

<h2><a name="win32">Building and Installing ACE on Windows</a></h2>

<p>This section contains instructions for building ACE on Microsoft
Windows with a variety of compilers and development environments.</p>

<p>First, if you are upgrading from an older release, the recommended practice
is to start with a clean directory. Unpacking the newer release over an older
one will not clean up any old files, and trying to use the environment's
"Clean" command will probably not account for all existing files.</p>

<p>For using MPC and our perl based test framework we recommend
our windows users to use <a href="http://www.activestate.com/Products/ActivePerl/"> Active
State Perl.</a></p>

</p><h3><a name="msvc">Building and Installing ACE on Windows with
Microsoft Visual Studio</a></h3>

<p>ACE contains project files for
Visual Studio 2009 (VC9), and Visual Studio 2010 (VC10).
Visual Studio 2005 supports building for
desktop/server Windows as well as for Windows CE and Windows Mobile. Since
not all users will be interested in the CE/Mobile capability, these platforms
have separate solution and project files from the desktop/server Windows.
Furthermore, VC7.1, VC8, VC9, and 10 use different file formats but the same file
suffixes (<code>.sln</code> and <code>.vcproj</code>). To support both
environments, ACE supplies files with different names for the different
development and target platforms. The platform/name mapping is shown below.
All solution files have a <code>.sln</code> suffix and all project files have
a <code>.vcproj</code> suffix.</p>

<p>
The free Visual C++ 2008 Express Edition will work in place of the traditional
Visual Studio editions.  All the other notes in this document
that are for VC8 / VC9 also apply to the express edition.  MFC, 64-bit, and
CE/mobile options are not available with the express edition.  64-bit binaries
can be built with the compiler and linker included in the <a href="http://www.microsoft.com/downloads/details.aspx?FamilyID=E6E1C3DF-A74F-4207-8586-711EBE331CDC&displaylang=en">Windows SDK</a>, using nmake as the build system (generate nmake makefiles with mwc.pl -type nmake).</p>

<p>The VC++ compiler and linker can now be invoked from GNU make just like
most UNIX builds.  Follow the instructions in the <a href="#unix_traditional">
ACE/GNU Configuration</a> sections and see the additional information in the
comments of
<a href="include/makeinclude/platform_win32_msvc.GNU">platform_win32_msvc.GNU</a>.
</p>

<p>If you happen to open a VC7.1 file from within VC8, it will offer to convert
the file to the newer format for you. With the stock VC8, do not do this;
Visual Studio will crash while attempting to convert the large
solution and project files to build ACE. Simply refuse the conversion and
open the file with the correct format. Note that Microsoft has fixed this
problem. See
<a href="https://msdn.microsoft.com/visualc/downloads/default.aspx">
https://msdn.microsoft.com/visualc/downloads/default.aspx</a> for information.
</p>

<ol>
  <li>Uncompress the ACE distribution into a directory, where it will
  create a ACE_wrappers directory containing the distribution.  The
  ACE_wrappers directory will be referred to as ACE_ROOT in the
  following steps -- so  ACE_ROOT\ace would be C:\ACE_wrappers\ace if
  you uncompressed into the root directory.<br>
      <br>
  </li><li>Create a file called <code>config.h</code> in the ACE_ROOT\ace
      directory that contains: <br>
      <br>
      <code>#include "ace/config-win32.h"</code><br>
      <br>

  </li><li>The static, DLL and MFC library builds are kept in
  different workspaces. Files with names *_Static contain project
  files for static builds. Workspaces for static and DLL builds will be
  available through the stock release at DOC group's website. The
  workspaces for MFC are not available and have to be generated using
  MPC. Please see <a href="MPC/docs/README">MPC's README</a> for
  details.<br><br>
  </li><li>Now load the solution file for ACE (ACE_ROOT/ACE.sln).<br>
      <br>
  </li><li>Make sure you are building the configuration (i.e, Debug/Release)
  the one you'll use (for example, the debug tests need the debug
  version of ACE, and so on).  All these different configurations are
  provided for your convenience.  You can either adopt the scheme to
  build your applications with different configurations, or use
  <code>ace/config.h</code> to tweak with the default settings on
  NT.<br>  <strong>Note:</strong> If you use the dynamic libraries,
  make sure you include ACE_ROOT\lib in your PATH whenever you run
  programs that uses ACE.  Otherwise you may experience problems
  finding ace.dll or aced.dll.<br>
      <br>
  </li><li>To use ACE with MFC libraries, also add the following to
      your <code>config.h</code> file.  Notice that if you want to
      spawn a new thread with CWinThread, make sure you spawn the
      thread with THR_USE_AFX flag set.<br>
      <br>
      <code>#define ACE_HAS_MFC 1</code><br>
      <br>
      By default, all of the ACE projects use the DLL versions of the
      MSVC run-time libraries.  You can still choose use the static (LIB)
      versions of ACE libraries regardless of run-time libraries.  The
      reason we chose to link only the dynamic run-time library is that
      almost every NT box has these library installed and to save disk
      space.  If you prefer to link MFC as a static library into ACE, you
      can do this by defining <code>ACE_USES_STATIC_MFC</code> in your
      <code>config.h</code> file.  However, if you would like to link
      everything (including the MSVC run-time libraries) statically,
      you'll need to modify the project files in ACE yourself.<p>
  </p></li><li>Static version of ACE libraries are built with
      <code>ACE_AS_STATIC_LIBS</code><br> defined.  This macro should
      also be used in application projects that link to static ACE
      libraries<br>
      <br>
      Optionally you can also add the line <br>
      <br>
      <code>#define ACE_NO_INLINE</code><br>
      <br>
      before the #include statement in ACE_ROOT\ace\config.h to disable
      inline function and reduce the size of static libraries (and your
      executables.)<br>
      <br>
  </li><li>ACE DLL and LIB naming scheme:<br>
      <br>
      We use the following rules to name the DLL and LIB files in ACE
      when using MSVC.<br>
      <br>
      "Library/DLL name" + (Is static library ? "s" :
      "") + (Is Debugging enable ? "d" : "")
      + {".dll"|".lib"}<br>
      <br>
</li></ol>

<a href="docs/msvc_notes.txt">here</a>.  The doxygen version of this
document is available under Related Topics in the ACE Library.</p>

<b>ACE TESTS</b><p>

The tests are located in ACE_ROOT\tests.  There is also a solution in
that directory to build all the tests (tests.sln)</p><p>

Once you build all the tests (Batch Build works well for this), you
can run perl script <code>run_test.pl</code> in the
<code>tests</code> directory to try all the tests.</p><p>

  <li>Uncompress the ACE distribution into a directory, where it will
      create an
      ACE_wrappers directory containing the source.  The ACE_wrappers
      directory will be referred to as ACE_ROOT in the following steps -- so
      <code>ACE_ROOT\ace</code> would be <code>C:\ACE_wrappers\ace</code> when you uncompressed into the

      <br>
  </li><li>Create a file called <code>config.h</code> in the ACE_ROOT\ace

      <br>
      <code>#include "ace/config-win32.h"</code><br>
      <br>
  </li><li>Open a RAD Studio Command Prompt.<br>
      <br>
  </li><li>Set the ACE_ROOT environment variable to point to the ACE_wrappers

      <br>
      <code>set ACE_ROOT=C:\ACE_wrappers</code><br>
      <br>
  </li><li>Add ACE_wrappers\lib and ACE_wrappers\bin to the PATH environment variable:<br>
      <br>
      <code>set PATH=%ACE_ROOT%\lib;%ACE_ROOT%\bin;%PATH%</code><br>
      <br>
  </li><li>Change to the ACE_ROOT\ace directory.<br>
      <br>
      <code>cd %ACE_ROOT%\ace</code><br>
      <br>
  </li><li>Generate the bmake makefiles using <a href="#MPC">MPC</a>. Use the <code>bmake</code> project type for C++ Builder:<br>
      <br>
      <code>%ACE_ROOT%\bin\mwc.pl -type bmake</code><br>
      <br>
  </li><li>You can build several different versions of ACE by setting the following optional environment
      variables before you run make:<br>
      <br>
      Set the environment variable below to build a debug version of ACE<br>
      <code>set DEBUG=1</code><br>
      <br>
      Set the environment variable below to build a unicode version of ACE<br>
      <code>set UNICODE=1</code><br>
      <br>
      Set the environment variable below to build a version of ACE with
      Codeguard support. Should only be used when DEBUG is also set<br>
      <code>set CODEGUARD=1</code><br>
      <br>
      By default we are using the clang based compilers. At the moment you
      want to compile using the old bcc32 compiler set the CLASIC environment variable<br>
      <code>set CLASSIC=1</code><br>
      <br>
      Set the environment variable below to build a version of ACE optimized
      for a certain CPU. For this there are special compiler flags
      (-3/-4/-5/-6), see the Embarcadero help for more info.<br>
      <code>set CPU_FLAG=-6</code><br>
      <br>
      You can then start the build with the command
      <br><code>make -f Makefile.bmak all</code><br>
      <br>
      You may also enable the options by passing them as command line options to make, for example:<br>
      <code>make -f Makefile.bmak -DDEBUG all</code><br>
      <br>
  </li><li>Build ACE by doing:<br>
      <br>
      <code>make -f Makefile.bmak all</code><br>
      <br>
</li></ol>

<p>

Note that when you run <code>make</code> in a sub directory you give <code>make -f Makefile.bmak all</code>. The <code>all</code> is needed to make sure the complete project is build.<p>

The C++ Builder port has been done by Jody Hagins, <a href="mailto:chris@kohlhoff.com">Christopher Kohlhoff</a> and <a href="mailto:jwillemsen@remedy.nl">Johnny Willemsen</a>. </p><p>

<b>ACE TESTS</b></p><p>

Before you can build the tests you need to build the protocols directory.
Change the directory to ACE_ROOT\protocols and start: </p><p>
</p><blockquote><code>
%ACE_ROOT%\bin\mwc.pl -type bmake<br>
make -f Makefile.bmak all
</code></blockquote><p>

The tests are located in ACE_ROOT\tests, change to this directory.
You build then the tests with the following commands:</p><p>
</p><blockquote><code>
%ACE_ROOT%\bin\mwc.pl -type bmake<br>
make -f Makefile.bmak all
</code></blockquote><p>

Once you build all the tests, you can run the automated test script using:</p><p>
</p><blockquote><code>perl run_test.pl</code></blockquote><p> in the
<code>tests</code> directory to try all the tests. You need to make
sure the ACE bin and lib directory (in this case
<code>%ACE_ROOT%\bin</code> and <code>%ACE_ROOT%\lib</code>)
are on the path before you try to run the tests. If your executables are
compiled into a subdirectory, add <code>-ExeSubDir subdirname</code> to the
command.</p><p>

</p><h3><a name="mingw">Building and Installing ACE on Win32 with MinGW/ MSYS</a></h3>

<p>
If you are building for a machine without a network card, you may want
to check <a href="#win32nonic">here</a> first.

</p><p>
Building and installing ACE on <a href="http://www.mingw.org/">MinGW</a>
uses a mix of a <a href="#unix">UNIX</a> building process and
<a href="#win32">Win32</a> configuration files.
Also, as MinGW uses GNU g++, you may want to take
a look at the <a href="#g++">Compiling ACE with GNU g++</a> section.

</p><p>
You will need the MinGW build tools and libraries, downloable from
<a href="http://www.mingw.org/"><tt>http://www.mingw.org</tt></a>.

<br>
For our build we require the packages
<b><tt>MinGW</tt></b> and <b><tt>MSYS</tt></b>.

</p><ol>

  <li> Install the MinGW tools (including the MinGW Development toolkit) into a common directory, say c:/mingw.
      <br><br>

  </li><li> Install the MSYS tools into a common directory, say c:/msys.
       <br><br>

  </li><li> Open a MSYS shell. Set your <tt>PATH</tt> environment variable so
       your MinGW's <tt>bin</tt> directory is first:

       <blockquote><code></code><pre>       % export PATH=/c/mingw/bin:$PATH
       </pre></blockquote>

  </li><li> Add an <tt>ACE_ROOT</tt> environment variable pointing to the
       root of your ACE wrappers source tree:

       <blockquote><code></code><pre>       % export ACE_ROOT=/c/work/mingw/ACE_wrappers
       </pre></blockquote>

       From now on, we will refer to the root directory of the ACE
       source tree as <tt>$ACE_ROOT</tt>.
       <br><br>

  </li><li> Create a file called <tt>config.h</tt> in the
       <tt>$ACE_ROOT/ace</tt> directory that contains:

       <blockquote><code></code><pre>       #include "ace/config-win32.h"
       </pre></blockquote>

  </li><li> Create a file called <tt>platform_macros.GNU</tt> in the
       <tt>$ACE_ROOT/include/makeinclude</tt> directory containing:

       <blockquote><code></code><pre>       include $(ACE_ROOT)/include/makeinclude/platform_mingw32.GNU
       </pre></blockquote>

       In the above text, don't replace <tt>$(ACE_ROOT)</tt> with the
       actual directory, GNU make will take the value from the
       environment variable you defined previously.

       <p>
       If you lack Winsock 2, add the line

       </p><blockquote><code></code><pre>       winsock2 = 0
       </pre></blockquote>

       before the previous one.
       <br><br>

     <p>
       If you want to install ACE (using "make install") and want all the <tt>.pc</tt> files generated,
     set the installation prefix in platform_macros.GNU.
       </p><blockquote><code></code><pre>      INSTALL_PREFIX=/c/ACE
       </pre></blockquote>
     Headers will be installed to $INSTALL_PREFIX/include, documentation and
     build system files to $INSTALL_PREFIX/share and libraries to $INSTALL_PREFIX/lib. With INSTALL_PREFIX set, RPATH will be enabled.
     To disable RPATH (for example, if $INSTALL_PREFIX/$INSTALL_LIB is already
     a system-known location for shared libraries), set the make macro

<p>
If you are building for a machine without a network card, you may want
to check <a href="#win32nonic">here</a> first.

</p><p>
Building and installing ACE on <a href="http://www.cygwin.com/">Cygwin</a>
uses the <a href="#unix">UNIX</a> building process.
Also, as Cygwin uses GNU g++, you may want to take
a look at the <a href="#g++">Compiling ACE with GNU g++</a> section.

</p><p>
You will need the Cygwin build tools and libraries, downloable from
<a href="http://www.cygwin.com/"><tt>http://www.cygwin.com</tt></a>.
For our build we require the following packages besides the packages the
setup selects by default:
<a name="cygwinpacks">
</a></p><blockquote>
<a name="cygwinpacks"><b><tt>gcc (version 3.3.3), cygserver, make, perl, binutils</tt></b>.
</a></blockquote>

<ol>

<a name="cygwinpacks">  <li> Install Cygwin (this can be easy downloading and running
       <a href="http://cygwin.com/setup.exe"><tt>setup.exe</tt></a>
       from the Cygwin site). For working with ACE we recommend
       to select <code>DOS</code> as default text file type.
       <br><br>

  <li> Open a Cygwin shell. Set your <tt>PATH</tt> environment variable so
       your Cygwin <tt>bin</tt> directory is first:

       <blockquote><code></code><pre>       % export PATH=//c/cygwin/bin:$PATH
       </pre></blockquote>

       or

       <blockquote><code></code><pre>       % export PATH=/cygdrive/c/cygwin/bin:$PATH
       </pre></blockquote>

       <p>
       Note Cygwin uses ``<tt>/</tt>'' as directory separator,
       and ``<tt>//X</tt>'' as a notation for Win32 drive <tt>X</tt>.
       Note also that you <em>can't</em> use ``<tt>c:/cygwin/bin</tt>''
       because, for Cygwin,
       ``<tt>:</tt>'' is path separator character, as in UNIX.
       <br><br>

  </p></li><li> Add an <tt>ACE_ROOT</tt> environment variable pointing to the
       root of your ACE wrappers source tree (in this example c:/work/cygwin/ACE_wrappers):

       <blockquote><code></code><pre>       % export ACE_ROOT=/cygdrive/c/work/cygwin/ACE_wrappers
       </pre></blockquote>

       <p>
       Note here you <em>can't</em> use the ``<tt>//X</tt>'' Cygwin
       notation as this is seen by Cygwin's compiler and it doesn't
       support that (it <em>does</em> support ``<tt>/</tt>'' as directory
       separator however).

       </p><p>
       From now on, we will refer to the root directory of the ACE
       source tree as <tt>$ACE_ROOT</tt>.
       <br><br>

  </p></li><li> Create a file called <tt>config.h</tt> in the
       <tt>$ACE_ROOT/ace</tt> directory that contains:

       <blockquote><code></code><pre>       #include "ace/config-cygwin32.h"
       </pre></blockquote>

  </li><li> Create a file called <tt>platform_macros.GNU</tt> in the
       <tt>$ACE_ROOT/include/makeinclude</tt> directory containing:

       <blockquote><code></code><pre>       include $(ACE_ROOT)/include/makeinclude/platform_cygwin32.GNU
       </pre></blockquote>

       In the above text, don't replace <tt>$(ACE_ROOT)</tt> with the
       actual directory, GNU make will take the value from the
       environment variable you defined previously.

  </li><li> On the Cygwin shell, change to the $ACE_ROOT/ace directory and
       run make:

       <blockquote><code></code><pre>       % cd $ACE_ROOT/ace
       % make
       </pre></blockquote>

       <p>
       This should create <tt>libACE.dll</tt> (the Win32 shared library) and
       <tt>libACE.dll.a</tt> (the Win32 import library for the DLL).
       Note the name for the ACE DLL on Cygwin follows the UNIX convention.
       <br><br>

       </p><p>
       If you want static libs also, you may run:

       </p><blockquote><code></code><pre>       % make static_libs_only=1
       </pre></blockquote>

  </li><li> <a name="cygwinrunpath">

</p><h2><a name="vxworks">Building and Installing ACE on VxWorks</a></h2>
For the most part, you should be able to follow the instructions above
to build ACE and applications that use it.  Start with the
<a href="#unix">Unix instructions</a> above to build ACE and the
applications that use it.  Please see below for more information on
<a href="#VxWorks/NT">building ACE on NT hosts for VxWorks targets</a>.<p>

A few notes on VxWorks builds (thanks to
<a href="mailto:Paul_von_Behren@stortek.com">Paul von Behren</a> and
<a href="http://www.remedy.nl">Remedy IT</a> for these notes):</p>
<p>
</p><ul>
  <li>VxWorks builds are done with a cross compiler, i.e., the compiles
      are done on a workstation creating object modules which are
      downloaded and loaded into the VxWorks target system.<p>
  </p></li><li>C++ object modules must be post-processed by a VxWorks
      utility called "munch" to set up calls to static constructors and destructors.
      ACE integrates the makefile includes/rules files
      distributed with VxWorks to achieve maximum compatibility and reuse the target
      specifications and buildcommands defined by Windriver itself.
      The original ACE support for VxWorks included a perl script called
      <a href="bin/ace_ld">$ACE_ROOT/bin/ace_ld</a>,
      which was called from the Makefiles, replacing
      the traditional <code>ld</code> step. Although this script is currently still
      available it is not used anymore.<BR>
      You must have perl installed to use <code>ace_ld</code>.  If perl is not on your path, you'll
      have to set <code>PERL_PATH</code> to the full path (including
      perl.exe), either in your
      <code>$(ACE_ROOT)/include/makeinclude/platform_macros.GNU</code>
      or in your environment.<p>
  </p></li><li>Wind River provides GCC/G++ cross-compilers for the
      supported target platforms.  The executables are named cc&lt;target&gt;
      and g++&lt;target&gt;; for example, ccppc and g++cpp for PowerPC
      targets.<p>
</p></li></ul>

You'll have to let ACE know the target type at compile time.  There
are several ways to do this; please see the
<code>$ACE_ROOT/include/makeinclude/platform_vxworks5.5.x.GNU</code>
platform file for detailed information.<p>

The VxWorks platform_vxworks*.GNU files are set up so that shared
libraries are not built on VxWorks, by default.  Only static
libraries, with .a extension, are built.  Therefore, it's not
necessary to set the LD_LIBRARY_PATH environment variable on your host
system when building for VxWorks targets.  Please note, however, if
you use TAO on VxWorks that you will need to set your LD_LIBRARY_PATH
to find the TAO IDL compiler libraries (installed in the ace
directory) on the host.</p><p>

These non-default VxWorks kernel configuration <code>#defines</code>
are required with ACE:</p><p>

</p><pre>#define INCLUDE_CPLUS           /* include C++ support */
#define INCLUDE_CPLUS_IOSTREAMS /* include iostreams classes */
#define INCLUDE_POSIX_ALL       /* include all available POSIX functions */
</pre>

For completeness, here are the non-default <code>#defines</code> that
we used for VxWorks 5.3.1/g++ 2.7.2:

<pre>#define INCLUDE_CPLUS           /* include C++ support */
#define INCLUDE_CPLUS_IOSTREAMS /* include iostreams classes */
#define INCLUDE_CONFIGURATION_5_2 /* pre-tornado tools */
#define INCLUDE_DEBUG           /* pre-tornado debugging */
#define INCLUDE_LOADER          /* object module loading */
#define INCLUDE_NET_SYM_TBL     /* load symbol table from network */
#define INCLUDE_SYM_TBL_SYNC    /* synchronize host and target symbol tables */
#define INCLUDE_NFS             /* nfs package */
#define INCLUDE_PING            /* ping() utility */
#define INCLUDE_POSIX_ALL       /* include all available POSIX functions */
#define INCLUDE_RDB             /* remote debugging package */
#define INCLUDE_RLOGIN          /* remote login */
#define INCLUDE_RPC             /* rpc package */
#define INCLUDE_SECURITY        /* shell security for network access */
#define INCLUDE_SHELL           /* interactive c-expression interpreter */
#define INCLUDE_SHOW_ROUTINES   /* show routines for system facilities*/
#define INCLUDE_SPY             /* spyLib for task monitoring */
#define INCLUDE_STARTUP_SCRIPT  /* execute start-up script */
#define INCLUDE_STAT_SYM_TBL    /* create user-readable error status */
#define INCLUDE_SYM_TBL         /* symbol table package */
#define INCLUDE_UNLOADER        /* object module unloading */
#define INCLUDE_WINDVIEW        /* WindView command server */
</pre>

Also, automatic construction/destruction of static objects
should be enabled.<p>

If you use TAO, it's also a good idea to increase the
<code>NUM_FILES</code> parameter from its default of 50 to,
say, 1000.</p><p>

Please note that those VxWorks kernel configuration parameters
are set in the VxWorks configAll.h file.  You must rebuild your
VxWorks kernel after modifying that file.</p><p>

If you're first getting started with ACE and/or VxWorks, I recommend
just building the ACE library and tests first.  (Some of the ACE
examples, in System_V_IPC, don't build on VxWorks yet.)  Then try
running the tests.  Please see $ACE_ROOT/tests/README for the latest
status of the ACE tests on VxWorks.</p><p>

Please note that the <code>main</code> entry point is renamed to
<code>ace_main</code> (configurable via ACE_MAIN) on VxWorks with g++,
to comply with its restriction against using <code>main</code>.
In addition, ACE_HAS_NONSTATIC_OBJECT_MANAGER is enabled by default
to cleanly support construction and destruction of static objects.
Please see the <a href="#NonStaticObjectManager">Non-static
ACE_Object_Manager</a> discussion for the important implication
of this feature.</p><p>

ACE threads (VxWorks tasks) can be named, for example, by supplying a
non-null argument to the Thread_Manager spawn routines.  However,
names beginning with <code>"==ace_t=="</code> are forbidden because
that prefix is used internally by ACE.</p><p>

You can spawn a new task to run <code>ace_main</code>, using either
VxWorks <code>sp</code>, or ACE'S <a name="spa"><code>spa</code></a>.
<code>spa</code> can be used from the VxWorks shell to pass arguments
to <code>ace_main</code>.  Its usage is:

</p><pre><code>
spa ace_main, "arg1" [, ...]
</code></pre>

All arguments must be quoted, even numbers. You can start also ace_main
without spawning another thread by using:<p>

</p><pre><code>
spaef ace_main, "arg1" [, ...]
</code></pre>

ACE also provides the function <code>vx_execae</code> which is capable of running
<code>ace_main</code> in a separate thread, wait for the task to finish and return
the return code from <code>ace_main</code>:

<pre><code>
int vx_execae (FUNCPTR acemain,char* arguments, int prio = 0, int opt = 0, int stacksz = 0);
</code></pre>
<p>
You could call this from the VxWorks shell like:
</p>
<pre><code>
my_rc = vx_execae ace_main, "-o server.ior -ORBDottedDecimalAddresses 1"
</code></pre><p>

When <code>prio</code>, <code>opt</code> or <code>stacksz</code> are omitted or specified
as <code>0</code> default values will be used. See the VxWorks shell documentation for the
defaults for <code>prio</code> and <code>opt</code>. For <code>stacksz</code> the default is
<code>ACE_NEEDS_HUGE_THREAD_STACKSIZE</code>.
The <code>arguments</code> string will be parsed and passed on to <code>ace_main</code> as
a regular <code>argc</code> and <code>argv</code>.</p><p>

Be aware of the fact that when you execute <code>ace_main</code> directly from the VxWorks
shell argc will be zero and argv* will also be zero. Using <code>argv[0]</code> will not return
the program name, but will result in a crash.<br>
The ACE helper functions <code>spa</code>, <code>spaef</code> and <code>vx_execae</code> prevent
this problem by building a regular <code>argc</code> and <code>argv</code> which also contain a
valid <code>argv[0]</code> element.</p>

<h3><a name="VxWorks/SharedLibs">Building Shared Libraries for VxWorks</a>.</h3>

<strong>NOTE</strong>: Since VxWorks support is currently being reworked with
an initial focus on static builds the support for shared builds is momentarily
broken. This will be remedied(!) as soon as possible.<p>

ACE supports shared libraries for VxWorks, but only with the g++
compiler.  To build shared libraries instead of the default static
libraries, added <code>shared_libs_only=1</code> to either your
<code>ACE_wrappers/include/makeinclude/platform_macros.GNU</code> or
your <code>make</code> invocation.  Then, be sure to load the ACE (and
any other) shared library before loading your executable(s).</p><p>

A shared library for VxWorks uses the same code as for a static
(non-shared) library.  However, calls to static constructors/
destructors are added.  The code in the shared library <strong>must</strong>
be reentrant if you shared it between programs (tasks).  The
ACE library meets this requirement.</p><p>

Shared libraries reduce build time, executable size, and load
time of the executable.  But, you must manually load the shared
library before loading your executable(s) with a command such as:
</p><pre><code>
-&gt; ld &lt; libACE.so
</code></pre>
Shared libraries can be unloaded the same way an executable
(module) is unloaded.<p>

<strong>NOTE</strong>: Shared libraries on VxWorks aren't the same as
shared libraries on other operating systems.  In particular, there is
no support for creating copies of writeable global (static) data in
the shared library.  This includes the singleton ACE_Object_Manager
instance pointer.  If you share global data between separate programs,
they may not work properly.  See the discussion of shared code and
reentrancy in the VxWorks' <em>Programmers Guide</em>.</p><p>

Instead of trying to run separate programs onto a VxWorks target, we
recommend creating just one program, and spawning a thread for each
task.  The TAO IDL_Cubit test <a href="TAO/performance-tests/Cubit/TAO/IDL_Cubit/collocation_test.cpp">collocation
test</a> is a good example.</p><p>

</p><h3><a name="VxWorks/LinkToKernel">Linking ACE and/or TAO Libraries into the VxWorks Kernel</a>.</h3>

It's easy to link your ACE and/or TAO libraries into the VxWorks kernel.
Just build <a href="#VxWorks/SharedLibs">shared versions</a>, but
disable the munch step.  The easiest way to do that is to set the
<code>LD</code> make variable to the name of your linker.  For
example, to build a libACE.so for PowerPC that can be linked into
the kernel:
<pre>% cd $ACE_ROOT/ace
% make LD=ldppc shared_libs_only=1
</pre>
After building the shared lib, link it into the kernel by setting
the <code>MACH_EXTRA</code> make variable in the kernel configuration
Makefile.  Then, build the kernel using <code>make exe</code>.<p>

</p><h3><a name="VxWorksTestScript">Using the one-button ACE tests with VxWorks</a>.</h3>

It is possible to generate a script to execute all ACE tests. You can do this by executing
</a></p><blockquote><code></code><pre><a name="vxworksscript">% perl run_test.pl -v -o > run_test.vxworks
</a></pre></blockquote>

The ACE tests write their output files in a directory named
<code>log/</code>, below the current (<code>tests</code>) directory.<br/>
</p>
<p>
To run the tests from the build directory on an NT host where you crossbuild your
VxWorks ACE/TAO you can set up the Target Server File System (TSFS) in your Target Server
configuration. If you f.i. set the root for the TSFS to the root directory of your builddisk
you can set the default directory for the target by issueing the following command
from a Host shell: '@cd "/tgtsvr/{path to ACE}/ACE_wrappers/tests"'.
The '@' addition makes sure this command is executed for the target environment and not the
local host shell environment.
If you also issue the command 'cd {path to ACE}/ACE_wrappers/tests' you can execute the
generated one button testscript like: '&lt; run_test.vxworks'.
</p>
<p>
Running the ACE tests automatically from the ACE autobuild tool using Target Server and Host
shell options is also supported.
</p>
<p>
If you don't have NFS included in your VxWorks kernel, you can use these steps, provided by
<a href="mailto:clarence_m_weaver@md.northgrum.com">Clarence M. Weaver</a>,
to run the tests and capture their output:</p><p>
</p><ol>
  <li>What I did was create a log directory on the boot NT host of my VxWorks
    target.<p>
  </p></li><li>I copied all the test applications and the run_test.vxworks script to
    the parent of the log directory.<p>
  </p></li><li>Using the target shell not the host shell, I "cd" to the directory
    containing the script and test programs.<p>
  </p></li><li>Invoked the script using <code>&lt; run_test.vxworks</code> from this target shell.<p>
</p></li></ol>

<a href="mailto:Kirk.Davies@pobox.com">Kirk Davies</a> provided this
approach for running the ACE tests on Tornado II:

<ul>
  <li>Under Tornado II, I set up the Target Server File System (TSFS), and
    the test logs get written to the log subdirectory under that.<p>
  </p></li><li>You have to set an environment variable before running the tests:
<pre>putenv("ACE_TEST_DIR=/tgtsvr")
</pre><p>
</p></li></ul>

Please submit corrections, additions, or clarifications to the

<strong>NOTE:</strong>The make (version 3.74) that is provided with
Tornado 2.2 cannot be used to build ACE. A working version is available

Using the Cygnus tools, this approach works:
</p><ul>
  <li>You'll build both your NT and VxWorks executables in the same

    <code>ACE_wrappers/include/makeinclude/platform_macros.GNU</code>
    as usual for VxWorks.  See
    <a href="include/makeinclude/platform_vxworks5.5.x.GNU">the
    g++/VxWorks platform file</a> for more information.<p>
  </p></li><li>Create an <code>ACE_wrappers/ace/config.h</code> file that looks
    something like the following.

</p></li></ul>

A few additional Windows Notes, from Paul von Behren:<p>
</p><ul>
  <li>Cygnus has created a Win32 API which is compatible with a
      "generic" Unix environment.  Using this library, they have ported a
      large collection of GNU tools to WinNT/95 - including a port of
      gcc/g++.  See <a href="http://www.cygnus.com/misc/gnu-win32/">http://www.cygnus.com/misc/gnu-win32/</a>
      A related link is <a href="ftp://ftp.cygnus.com/pub/gnu-win32/latest/">ftp://ftp.cygnus.com/pub/gnu-win32/latest/</a><p>
  </p></li><li>To set up the command-prompt build environment, run
      <code>Tornado\host\x86-win32\bin\TorVars.bat</code>.  This is done
      implicitly within the Tornado IDE.<p>
  </p></li><li>To run <code>ace_ld</code>, you still need perl installed -
      see <a href="http://www.activestate.com/software/default.htm">http://www.activestate.com/software/default.htm</a>
      for Windows perl.<p>
  </p></li><li>The Tornado IDE will use a standard Makefile for project
      builds, but does not have a GUI interface for managing the
      Makefile.  By default, it will use rules from Makefile in the current
      directory and you can configure it to add certain Makefile
      targets to the project.  If you have <code>ACE_ROOT</code> defined
      before starting Tornado, you can specify an ACE Makefile as a Tornado
      target and Tornado will then call make from the menu.<p>
</p></li></ul>

And Chris Ryan's instructions for building for VxWorks targets
on Windows NT hosts:

<ol>
  <li>Path setting that seems to be working is:<p>

      <code>aced.dll</code> is produced in an ACE NT source tree according to
      documented procedure for Windows VC++ ACE build.

      <code>cygwin.dll</code> is from the Cygnus GNU software download and install.

  </li><li>Basically, follow documented procedure for ACE build/install on UNIX

      And create a
      <code>$ACE_ROOT/include/makeinclude/platform_macros.GNU</code>
      that looks like:<p>
      </p><pre>
      WIND_BASE = /tornado
      WIND_HOST_TYPE = x86-win32
      CPU = I80486
      include $(ACE_ROOT)/include/makeinclude/platform_vxworks5.5.x.GNU
      </pre>

 </li><li>When using cygnus windows GNUTools on WinNT you have to start
 make with "--unix" option, otherwise WinNT shell cmd.exe is responded and
 not sh.exe, i.e.,
 <pre> make --unix static_libs_only=1
 </pre>
</li></ol>

<h3>TAO on NT Tornado host, VxWorks target.</h3>

<ol>
  <li>Build ACE and TAO_IDL in the NT tree as already documented.
      Be sure to build ACE's gperf on NT, in
      <code>ACE_wrappers/apps/gperf/src</code>.<p>

  </p></li><li>Build $TAO_ROOT/tao

Notes for Building ACE and TAO for VxWorks on NT host</h3>
<b></b><p><b>Scenario:</b>  I was building the ACE and TAO for VxWorks
on NT. The target system was a PPC860 based chassis and another a NT
host based card.</p>
<b><p>Host System:</p>
</b><p>NT 4.0 workstation with 128 M RAM, 266MHz Pentium.</p>

<b><p>Software Needed For Building TAO</p>
</b><p>1) Active State's ActivePerl from
<a href="http://www.activestate.com/software/default.htm">http://www.activestate.com/software/default.htm</a>
</p>

<p>2) Tornado 2.2.1 from Windriver.</p>

<p>3) Cygwin GNU to build TAO. It is available for NT as a freeware
from the <a href="http://www.cygwin.com">Cygwin</a> site</p>
<p>The Cygwin Make (version 3.75) can only build the TAO not the

<p>ACE_COMPONENTS=FOR_TAO (you may choose this option to build ACE
library that supports TAO)</p>

<p></p>
<b><p>Steps to Build</p>
</b><p>1) Build Ace.dll under NT</p>
<p>In  MS Visual C++ open C:\Corba\ACE_wrappers\ace.sln And build Ace
DLL</p>
<p>Copy Ace.dll in C:\bin</p>

<p>2) Build gperf utility under NT</p>
<p>In MS Visual C++ open
C:\Corba\ACE_wrappers\apps\gperf\src\gperf.sln. Build gperf.exe</p>
<p>Copy gperf.exe to C:\bin</p>

<p>3) Mount Directries in Cygwin</p>
<p>Click on Cygnus Solutions -&gt; Cygwin Bash Shell</p>
<p>Mount following directories by using mount command.</p>
<p>create respective directories first then use mount command </p>

<p>e.g. Create /Corba directory then use $mount -s "C:\Corba"
/Corba</p>

<p>C:\Corba  mount to /Corba</p>
<p>C:\tornado mount to /tornado</p>
<p>C:\Perl  mount to /perl</p>
<p>C:\Cygwin  mount to /cygwin</p>
<p>C:\bin  mount to /bin</p>
<p>C:\Program Files mount to /Program Files </p>

<p>4) Build ACE in Cygwin</p>
<p>$cd /Corba/ACE_wrappers/ace </p>
<p>$make static_libs_only=1</p>
<p>This will build your ace library libACE.a for VxWorks. If you use
option shared_libs_only=1 then the build will be libACE.so. The other
options are same as follows.</p>

<p>5) Build TAO in Cygwin</p>
<p>$cd $TAO_ROOT/tao</p>
<p>$make debug=0 optimize=1 static_libs_only=1 minimum_orb=1
</p>
<p>for shared libs use shared_libs_only=1</p>

<p>The minimum Tao does not have following components,</p>
<p>Dynamic Skeleton Interface</p>
<p>Dynamic Invocation Interface</p>
<p>Dynamic Any</p>
<p>Interceptors</p>
<p>Interface Repository</p>
<p>Advanced POA features</p>
<p>CORBA/COM interworking</p>

<p>You may play around with above options to find suitable build for
your needs. For example when you give option debug=1 all the debug
symbols will be created and the build will huge in size. The debug
symbols are necessary when you want to debug your code.</p>

<p></p><h2><a name="android">Building and Installing ACE on Android</a></h2>
<p>ACE can be built for Android by using the <a href="http://developer.android.com/tools/sdk/ndk/index.html">Android Native Development
Kit's</a> standalone toolchain. Testing has been performed with
NDK6 and NDK8e. The compilation creates native binaries,
not the standard Android Java applications.  The native binary applications
that use ACE can be run by either a shell or using the Java Runtime exec
operation.</p>

<p>The standalone toolchain must configured for a platform of android API level 8, 9, or 14. From your NDK root directory you can use their
<code>make-standalone-toolchain.sh</code> script to set this up. For example:</p>
<code>./build/tools/make-standalone-toolchain.sh --toolchain=arm-linux-androideabi-4.4.3 --arch=arm --platform=android-9 --install-dir=../arm_tools</code>
<p>To set up an arm-specific tool chain. With the release of NDK r6, x86 targets are supported, so the setup command for that would be:</p>
<code>./build/tools/make-standalone-toolchain.sh --toolchain=x86-4.4.3 --arch=x86 --platform=android-9 --install-dir=../x86_tools</code>
<p>
The bin directory under the installed standalone toolchain dir must be added to your $PATH</p>
<p>
When using the Android NDK on a 64bit Linux system you have to install the
following 32bit packages: <code>libstdc++.i686 glibc.i686 ncurses-libs.i686 zlib.i686</code>
</p>
<p>Starting with NDK8e it is possible to use shared libraries on Android.</p>

<p>Compilation requires using the NDK's standalone toolchain for it's
exception and RTTI support.  The standard NDK compiler is not identified
as supporting exceptions or RTTI, as of NDK r5c.</p>

<p>It is not recommended to perform the build on a Windows host.  Using the
NDK r5c, compilation issues were encountered on Windows XP, when the compiler
failed to recognize the name difference between the ACE file Signal.h and
the system file signal.h.</p>

<p>You should be able to follow the instructions above to build ACE
and applications that use it.  Use the
<a href="#unix_traditional">Unix  traditional instructions</a> above to build
ACE and the applications that use it.  Building TAO for Android requires
cross compiling the code.<p>

<p>Basic steps to build
<ul>
  <li>Setup up the standalone compiler toolchain by following the
 instructions provided with the Android NDK.</li>
  <li>If building TAO, build the ACE and TAO tools (<code>ace_gperf</code> and
 <code>tao_idl</code>) for the compiling host.  Follow the cross compilation setup instructions provide
 in $TAO_ROOT/TAO-INSTALL.html.  Search for "Using cross compilation".</li>
  <ul>
    <li>Setup the Android build<ul>
      <li>Create <code>ace/config.h</code>:  <i>#include "ace/config-android.h"</i></li>
      <li>Create <code>include/makeinclude/platform_macros.GNU</code>:
        <ul>
          <li>set options for debug and optimized builds</li>
          <li>inline is forced on and no-hidden-visibility</li>
          <li>if you want to compile static, add <code>static_libs_only=1</code></li>
          <li>Include the <code>include/makeinclude/platform_android.GNU</code> file.</li>
          <li>If building TAO, set the tao idl options specified in the cross compiling instructions in <code>TAO-INSTALL.html</code></li>
        </ul>
      <li>Ensure the following environment variables are set:
        <ul>
          <li>$ANDROID_ARCH - either arm or x86. Note that x86 is only available in r6 and greater, and is still experimental. ANDROID_ARCH will be set to arm by default.</li>
          <li>$NDK - the path to the android native development kit</li>
          <li>$SYSROOT - the platform/arch directory. This defaults to <code>$NDK/platforms/android-9/arch-$ANDROID_ARCH</code>. </li>
          <li>$HOST_ROOT - the path to the native TAO_IDL & gperf tools</li>
          <li>$PATH - must include <code>$NDK_TOOLS/bin</code>.</li>
        </ul>
      </ul>
    </li>
    </li>
    <li>Generate makefiles (if necessary).</li>
    <li>Build with GNU make.</li>
  </ul>
</ul>
</p>

<p>Native applications using the ACE library can be installed onto devices by
several different methods.  The files can be include as assets of Java
application and can be written by the Java application into it's executable
program directory.  The native application can be downloaded by a Java
application and written into the Java applications executable program
directory.  The native application can also be uploaded using the Software
Development Kit's ADB tool.  This method requires uploading the native
application to a directory that allows execution and having any output
directed to a writable directory.</p>

<h1><a name="svcsinstall">Building and Installing ACE Network Services</a></h1>

The following explains how to build the ACE <a href="http://www.cs.wustl.edu/%7Eschmidt/ACE-netsvcs.html">network services</a> on <a href="#unixsvcs">UNIX</a> and <a href="#win32svcs">Win32</a>.

<p></p><hr align="left" width="50%"><p>
</p><h2><a name="unixsvcs">Building and Installing ACE Network Services on UNIX</a></h2>

Building and installing ACE Network Services on UNIX is relatively
simple (the <a href="#win32svcs">process</a> for Win32 is different).
Here's what you need to do:<p>

</p><ol>

  <li>Build and install ACE on UNIX as described <a href="#unix">earlier</a>.  If ACE is built at the root of the ACE
      source tree (and ACE has been ported to your platform, of course) the
      netsvcs static and shared object libraries should be built
      automatically.  In addition, the server driver program
      (<code>main</code>) contained in <a href="netsvcs/servers/main.cpp">$ACE_ROOT/netsvcs/servers/main.cpp</a>
      should also be compiled and ready to run.<p>

  </p></li><li>Set your <code>LD_LIBRARY_PATH</code> environment variable to
      where the binary version of the ACE netsvcs library.  For
      example, you probably want to do something like the following<p>

      </p><pre><code>
      % setenv LD_LIBRARY_PATH $ACE_ROOT/ace:$ACE_ROOT/lib:$LD_LIBRARY_PATH
      </code></pre><p>

  </p></li><li>By default, if the shared object library is built, the services
      are linked into the <code>main</code> driver program dynamically.
      To specify which services should be linked in and executed, edit the
      <a href="netsvcs/servers/svc.conf">$ACE_ROOT/netsvcs/servers/svc.conf</a>
      file.  During your editing, you should update information (such as the
      default service port numbers) that affects the initialization of
      services in this file.  Refer to the
      <a href="http://www.cs.wustl.edu/%7Eschmidt/ACE_wrappers/ACE-papers.html#config">Service Configurator</a>
      documentation to learn how the configuration file is parsed and
      how the services are dynamically linked and executed.  In
      addition, refer to the <a href="http://www.cs.wustl.edu/%7Eschmidt/ACE-netsvcs.html">Network
      Services</a> documentation to learn more about how to configure
      each network service.<p>

  </p></li><li>If you only want to link the services statically, simply remove
      or rename the svc.conf file.<p>
</p></li></ol>

<h1><a name="sslinstall">Building and Installing the ACE_SSL Library</a></h1>

<p>The first step for all platforms is to build and install the
<a href="http://www.openssl.org/">OpenSSL</a> distribution.  The
ACE_SSL library must then be built according to the instructions
below.</p>
<h2>Unix</h2>
<ol>
  <li>Make sure the OpenSSL header file directory is in your compiler's
      include path, and that OpenSSL libraries are in your library link/load
      path (e.g. <code>LD_LIBRARY_PATH</code>). If you
      installed OpenSSL into a set of directories unknown by the compiler,
      set the <code>SSL_ROOT</code> environment variable to point to the
      top level directory of your OpenSSL distribution, i.e. the one
      containing OpenSSL's <code>include</code> and <code>lib</code>
      directories.</li>
  <li>Build ACE as described above. When building ACE, add
      <code>ssl=1</code>
      to your <code>make</code>
      command line invocation, or add it to your
      <code>platform_macros.GNU</code> file.</li>
  <li>Build the ACE_SSL library in the <tt>$ACE_ROOT/ace/SSL</tt>
      directory. The <code>ACE_ROOT</code> environment variable should be set
      prior to this point.</li>
</ol>
<h2>Microsoft Visual Studio</h2>
<ol>
  <li>Set the <code>SSL_ROOT</code> environment variable to the location
      of the directory containing the OpenSSL <code>inc32</code> and
      <code>out32dll</code> directories.
  <li>Add <code>ssl=1</code> to your MPC
      <code>$ACE_ROOT/bin/MakeProjectCreator/config/default.features</code>
      or <code>$ACE_ROOT/local.features</code> file.
  <li>At the moment you are using OpenSSL v1.1 or
      newer also add <code>openssl11=1</code> to your MPC
      <code>$ACE_ROOT/bin/MakeProjectCreator/config/default.features</code>
      or <code>$ACE_ROOT/local.features</code> file.
  <li>Re-run MPC to add
      support for building the ACE_SSL library to your MSVC++
      workspaces and projects.
  <li>Open the <code>ACE.sln</code> solution, and refer to the ACE build
      and installation instructions above for details on creating a
      <code>config.h</code> configuration header for this platform.  Once
      the <code>config.h</code> file has been created, build the
      <code>ACE_SSL</code> project.</li>
</ol>
<h2>Embarcadero C++</h2>
<p>Support for building ACE's ACE_SSL library and TAO's SSLIOP
   pluggable protocol with Embarcadero C++ does exist.
<ol>
  <li>Set the <code>SSL_ROOT</code> environment variable to the location
      of the directory containing the OpenSSL <code>inc32</code> and
      <code>out32</code> directories.
  <li>Add <code>ssl=1</code> to your MPC
      <code>$ACE_ROOT/bin/MakeProjectCreator/config/default.features</code>
      or <code>$ACE_ROOT/local.features</code> file, and re-run MPC to add
      support for building the ACE_SSL library to your Embarcadero C++ makefiles.
  <li>Build ACE and TAO.
</ol>

</p><h1><a name="guireactor_install">Building and Using GUI Reactors Libraries</a></h1>
There is a general method for building and using <code>ACE_Reactors</code> for various GUI
libraries.
    <h2> Building GUI Reactor Library </h2>
    <ol>
      <li>Try to generate build files using MPC. Inspect the output of MPC to find out which features are
        necessary to build given reactor. Add these features to
        <code>ACE_wrappers/bin/MakeProjectCreator/*.features</code> file, or pass them directly to MPC
        using <code>-features</code> command line option. For example, for <code>FlReactor</code> the procedure
        consists of five steps
        <ol>
          <li> In the first pass one gets that <code>x11</code> (X11 libraries) is missing.<br>
            <code>$ mwc.pl -type gnuace
              Skipping ACE_FlReactor (ace_flreactor.mpc), it requires x11.
            </code></li>
            Ensure that <code>X11</code> libraries are installed, then pass <code>x11=1</code> feature to MPC.
          <li>In the second pass one gets that <code>gl</code> (OpenGL library) is missing.<br>
            <code>$ mwc.pl -type gnuace -features x11=1 ace.mwc
              Skipping ACE_FlReactor (ace_flreactor.mpc), it requires gl.
            </code></li>
            Ensure that <code>OpenGL</code> libraries are installed, then pass <code>gl=1</code> feature to MPC.
          <li>In the third pass one gets that <code>fl</code> (Fast Light Toolkit) is missing.<br>
            <code>$ mwc.pl -type gnuace -features x11=1,gl=1 ace.mwc
              Skipping ACE_FlReactor (ace_flreactor.mpc), it requires fl.
            </code></li>
            Ensure that <code>Fast Light Toolkit</code> libraries are installed, then pass <code>fl=1</code>
            feature to MPC.
          <li>In the fourth pass one gets that <code>ace_flreactor</code> feature is missing<br>
            <code>$ mwc.pl -type gnuace -features x11=1,gl=1,fl=1 ace.mwc
              Skipping ACE_FlReactor (ace_flreactor.mpc), it requires ace_flreactor.
            </code></li>
          Allow MPC to generate makefiles for <code>FlReactor</code> by setting <code>ace_flreactor=1</code> feature.
          <li>In the last pass one obtains files for building <code>FlReactor</code>.<br>
            <code>$ mwc.pl -type gnuace -features x11=1,gl=1,fl=1,ace_flreactor=1 ace.mwc
            </code></li>
        </ol>
        Currently to simplify MPC generation some of features are turned on by default in
        <code>ACE_wrappers/bin/MakeProjectCreator/global.features</code>. For examples to generate
        files related with Fl one has to provide only fl=1 feature. To obtain a more fine grained controll
        over MPC generation process one may modify <code>ACE_wrappers/bin/MakeProjectCreator/*.features</code>
        files.
      </li>
      <li> Required build files are generated now, it is enough then to invoke build tool.
      For example for under <code>MPC::gnuace</code> one has to call
      <code>make fl=1</code>. For <code>MPC::vc7</code> target all features are
      encoded in generated project files, thus it is enough to compile ACE using MSVC.
      </li>
  </ol>
    The build procedure leads to a specific GUI Reactor library. For example, for
    <code>Qt</code> and <code>Linux </code> one gets <code>libQtReactor.so</code>, while for
    <code>Windows</code> the results are shared <code>QtReactor.dll</code> and import
    <code>QtReactor.lib</code> libraries or their variants depending on build options.
    When compiling TAO also GUI related libraries are created like <code>libTAO_QtResource.so</code>.
  <h2> Using GUI Reactor Library </h2>
    Here one has at least three use cases:
    <ol>
    <li><b>Applications with their own build system.</b>
    To use ACE support for GUI one has to include specific GUI headers and
    link with specific <code>ACE_[GUI]Reactor</code> library. When using TAO support for GUI one has
    also to link with specific <code>TAO_[GUI]Resource</code> library.</li>
    <li><b>Applications with build system using MPC.</b>
    In general, it is better to create specific base projects for using ACE GUI support in such application.
    Base projects provided by ACE <code>ACE_wrappers/bin/MakeProjectCreator/[ace,tao]_[gui][reactor,resource].mpb</code>
    may be an examples of how to do this.</li>
    <li><b>Internal ACE applications like tests or examples.</b>
    MPC project for internal ACE application using GUI support should be derived from
    <code>ace_[gui]reactor.mpb</code> base projects. To employ TAO support for GUI one should derive
    the project from <code>tao_[gui]resource.mpb</code> These base projects ensure that all necessary libraries
    are linked to the application, specifies features necessary to build a project and moreover impose a
    build order consistant with ACE. For example, the application project using <code>XtReactor</code> should be
    derived from <code>ace_xtreactor.mpb</code>.</li>
   </ol>
  <h2>Notes on specific GUI Reactors</h2>
    <ul>
      <li> <code>QtReactor</code></li>
        The build is controlled by <code>ace_qtreactor</code> [1 by default] feature.
        To build this reactor one has to provide feature <code>qt</code> [0 by default] (Qt library). Moreover,
        it is assumed that <code>Qt</code> was installed in a standard way
        and <code>QTDIR</code> points to <code>Qt</code> installation folder. To build TAO
        support for <code>Qt</code> one should use <code>tao_qtresource</code> [1 by default] feature.
      <li> <code>XtReactor</code></li>
        The build is controlled by <code>ace_xtreactor</code> [1 by default] feature.
        To build this reactor one has to provide the following features: <code>x11</code> [1 by default]
        (X11 libraries) and <code>xt</code> [1 by default] (X11 Toolkit).
        Moreover, some examples and tests related with <code>XtReactor</code>
        needs additionall features namely either <code>motif</code> [0 by default] (Motif/Lesstif libraries) or
        <code>athena</code> [0 by default] (Athena widgets). To build TAO
        support for <code>xt</code> one should use <code>tao_xtresource
        </code> [1 by default] feature.
      <li> <code>TkReactor</code></li>
        The is controlled by <code>ace_tkreactor</code> [1 by default] feature. To build this reactor one has to provide
        <code>tk</code> [0 by default] (Tcl libraries) feature. To build TAO
        support for <code>Tk</code> one should use <code>tao_tkresource</code> [1 by default] feature.
      <li> <code>FlReactor</code></li>
        The  build is controlled by <code>ace_flreactor</code> [1 by default] feature.
        To build this reactor one has to provide the following features: <code>x11</code>
        [1 by default] (X11 libraries),
        <code>gl</code> [1 by default] (OpenGl) and <code>fl</code>
        [0 by default] (Fast Light Toolkit). To build TAO
        support for <code>Fl</code> one should use <code>tao_flresource</code> [1 by default] feature.
        <strong>MS Windows:</strong> The paths to <code>fltkdll</code> and
        <code>OpenGL32</code> libraries, as well as <code>fltk</code> header files
        should be setup manually for succesfull compilation. Obviosuly,
        <code>x11</code>switch is ignored for this platform.</li>

       or higher, Centerline C++ 2.x, GNU gcc 2.95 and
       later.</b><p>

      All the source code and tests should build and run without any
      problems on Solaris 7, 8, and 9 platforms using the above
      Sun C++ compilers.

      There are likely to be build problems with older versions or
      different patchlevels of Sun C++.  Likewise, on
      Solaris with g++ you may need to use GNU as instead of
      /usr/ccs/bin/as, if you want -gstabs+ and -pipe support.

      Thanks to Susan Liebeskind &lt;shl@janis.gtri.gatech.edu&gt;
      for providing the following useful information:</p><p>

      By default, ACE uses both the Solaris and POSIX thread
      interface.  To disable use of the Solaris thread interface, add
      <code>-D_POSIX_PTHREAD_SEMANTICS</code> to the
      <code>CFLAGS</code> in your
      <code>$(ACE_ROOT)/include/makeinclude/platform_macros.GNU</code>.
      See the Solaris Intro (3) man page for more information.</p><p>

      To disable ACE thread support completely, build with the
      <code>threads=0</code> make flag.  See the <a href="#flags">Makefile Flags</a> section below for more
      information on make flags.</p><p>

      If you use g++ on Solaris 7, you might need to rebuild
      it on a SunOS 5.7 (Solaris 7) host.  Some versions of g++
      provide replacements for system header files.  The
      replacements on older SunOS systems are not compatible with the
      SunOS 5.7 system headers.  </P>

  </li><li><b>AIX</b><p>

      ACE is currently supported on AIX 5.2 and higher using IBM's
      Visual Age C++ 6 and XL C++ 7 compilers as well as g++ 3.2.</p><p>

      The <code>ace/config-aix-5.x.h</code> file is recommended for all
      compilers on all AIX 5L versions. The Asynchronous I/O functionality
      is disabled by default because its use requires the system administrator
      to explicitly enable it in the kernel using SMIT. If this has been
      done and you want to enable asynchronous I/O support in ACE, add:
      <code>#define ACE_HAS_AIO_CALLS</code> to your <code>config.h</code>
      file before including <code>ace/config-aix-5.x.h</code>.</p><p>

      The Visual Age 6.0.0.3 and 6.0.0.4 do have some bugs that makes
      them unusable for building TAO. TAO has been tested with 6.0.0.12 and
      had no problems with that version.</p><p>

      For your <code>platform_macros.GNU</code> file, you should use
      <code>platform_aix_ibm.GNU</code> when building ACE with any of the
      IBM compilers and <code>platform_aix_g++.GNU</code> when building ACE
      with g++.</p><p>

      BTW, here's a technique from Rob Jordan &lt;<a href="mailto:jordan@hursley.ibm.com">jordan@hursley.ibm.com</a>&gt;
      that can reduce the size of the ACE libraries by about one
      third, and can also be applied to applications.  It works by
      optimising the sharing of template functions, which are created
      in an "unusual" way under AIX. It also speeds up
      compilation.</p><p>

      Here's how to optimise the ACE library generation:</p><p>

      Look at the <a href="ace/GNUmakefile.ACE">ace/GNUmakefile.ACE</a>
      in <code>$ACE_ROOT/ace</code>. Create a file called
      <code>ACE_All_Src.cpp</code>, and add a line to #include
      each of the source files
      listed under <code>FILES=</code> in the GNUmakefile. Create a
      file called <code>ACE_All_Tmp.h</code>
      and add a line to #include each of the .h files listed under
      <code>TEMPLATE_FILES=</code> in the GNUmakefile. Now update the
      GNUmakefile so that
      <code>FILES=ACE_All_Src</code> and
      <code>TEMPLATE_FILES=ACE_All_Tmp</code>.</p><p>

  </p></li><li><b><a name="Linux">Linux</a></b><p>

      ACE has been ported to <a href="http://www.cs.wustl.edu/%7Ecleeland/ace/">Linux</a> on
      Intel, Alpha, and PowerPC platforms.  If you use a RedHat 5.x
      distribution, it's best to use RedHat 5.1 or later.  ACE works
      without any modifications on RedHat 5.1 and later, and on
      Debian 2.1 on both Intel and Alpha.  Use the
      <code>platform_linux.GNU</code> and <code>ace/config-linux.h</code>
      in your <code>platform_macros.GNU</code> and
      <code>config.h</code> files, respectively.  The same
      files can be used on PowerPC, with LinuxPPC
      1999 (R5), with glibc 2.1.1.</p><p>

      If you run out of memory, it's easy to add virtual memory on
      Linux.  Please see the <code>mkswap</code> man page.  You'll
      need at least 256 to 300 Mb of virtual memory (RAM + swap) to
      compile all of ACE+TAO.  The <a href="#resource_requirements">System
      Resource Requirements section</a> has some suggestions on how
      to reduce the memory requirement.</p><p>

      The glibc 2.0 dynamic loader isn't thread safe. If you want to
      use the Invocation API you'll have to set
      <code>LD_BIND_NOW=true</code>. If you want to use
      <code>dlopen</code>, you should use <code>RTLD_NOW</code>.  The
      dynamic loader in glibc 2.1 is thread safe.</p><p>

      <strong>NOTE:</strong> The TAO NameService uses IP multicasting
      by default, though it is not required.  IP multicast on Linux
      requires the following:</p><p>

      </p><ul>
        <li>Enable IP multicast in the Linux kernel.  It is enabled in
            the default RedHat 5.1 kernel.  In older distributions, you
            can enable it by rebuilding your kernel with CONFIG_IP_MULTICAST
            enabled.<p>
        </p></li><li>Enable IP multicast in ACE.  It is enabled by default in
            <code>ace/config-linux.h</code>.  If you don't use
            IP multicast, add <code>#define ACE_HAS_IP_MULTICAST 0</code>
            to your <code>ace/config.h</code> before building ACE.<p>
        </p></li><li>There must be a network interface that is up and supports
            multicast.  If you have linuxconf, it's easiest to use that
            to add a network route for multicast (224.0.0.0) on one of
            your network interfaces, such as <code>eth0</code>.  If
            you don't have or use linuxconf, try adding a multicast
            routing table entry using something like this:<p>
            </p><pre>             <code># route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0</code>
            </pre><p>
      </p></li></ul>

      Some of the ACE tests fail on older, pre-glibc2 Linux platforms,
      such as RedHat 4.2.  The problems are with threads and
      thread-specific storage.</p><p>

  </p></li><li><b>SCO UNIX</b><p>

      ACE has been ported to SCO UNIX using the GNU g++ 2.7.2
      compiler.  Arturo Montes &lt;<a href="mailto:mitosys@colomsat.net.co">mitosys@colomsat.net.co</a>&gt;
      maintains this code.  In addition, he also maintains a version
      of <a href="http://www.cs.wustl.edu/%7Eschmidt/ACE_wrappers/FSU-threads.tar.gz">FSU pthreads</a>.</p><p>

  </p></li><li><b>SGI IRIX 5.x and 6.x</b><p>

      ACE used to build fine using the SGI C++ and GNU GCC compilers
      for IRIX 5.x.  It has been ported to IRIX 6.x using the SGI
      MipsPro 7.1 C++ compiler; be aware that in IRIX 6.2 there is a
      number of patches that have to be installed and exceptions
      appear to fail with the O32 ABI.  Please check the config files
      for the details.</p><p>

  </p></li><li><b>OSF/1 3.2 and 4.0 (a.k.a. Digital UNIX 4.0)</b> <p>

      The Digital UNIX C++ 5.4 through 5.7 compilers have problems
      with ACE's templates.  They compile the lib and most of the test
      programs, although they warn about template usage.  Most tests
      run, some dump core.  If you use a 5.x version of cxx, be sure
      to set the CXX_VER variable to CXX_5, either on your make
      command line or in an environment variable.  The ACE Makefiles
      assume by default that the cxx version is 6.x or later.</p><p>

      CXX 6.0 and 6.1 are much improved over 5.x: V6.0-020, V6.1-025,
      and later build all of ACE cleanly.  All of the tests in
      $(ACE_ROOT)/tests run successfully with CXX 6.0 and CXX 6.1.
      Please note that problems have been reported with some versions
      of CXX 6.1, notably versions -021 and earlier.  It's best to use
      V6.1-022 or later.</p><p>

      NOTE: if you use Digital UNIX 4.0f or later, you <strong>must</strong>
      use <code>ace/config-tru64.h</code> instead of
      <code>ace/config-osf1-4.0.h</code>.  <code>ace/config-tru64.h</code>
      can be used for all supported compilers on any version of
      Digital UNIX after and include 4.0.  And, with 4.0f and later when
      using Digital CXX, you <strong>must</strong> use
      <code>include/makeinclude/platform_tru64_cxx.GNU</code> instead of
      <code>include/makeinclude/platform_osf1_4.0.GNU</code>.</p>

  </li><li><b> FreeBSD </b><p>

      FreeBSD is a fast evolving platform.  However, it has the
      advantage of having standard releases.  At this moment, ACE is
      only perodically tested against -stable (3.1R) and we rely a lot
      on FreeBSD users' feedbacks.  </p><p>

      Notice that on older FreeBSD, <code>ld.so</code> only looks for
      so libraries with <b>version number</b> appended.  ACE makefiles
      create symlinks for most shared libraries if
      <code>versioned_so</code> is defined to 1 in
      <code>$ACE_ROOT/ace</code> with appropriate ACE version.
      However, this does not work for libACE.so itself so you have to
      create it manually (If you figure out how to do this, please let
      us know) like this: </p><p>

      <code>ln -sf $ACE_ROOT/ace/libACE.so $ACE_ROOT/ace/libACE.so.4.5</code></p><p>

      On newer FreeBSD (3.0 or later,) this is no longer necessary.</p><p>

  </p></li><li><b>NetBSD</b><p>

      Like older FreeBSD, NetBSD's <code>ld.so</code> also requires
      versioned .so files.</p><p>

  </p></li><li><b>OpenBSD</b><p>

      ACE has been ported to OpenBSD 3.1 and GNU g++ 2.95.3.</p><p>

      As with FreeBSD and NetBSD, OpenBSD requires versioned .so
      files.  This is currently handled by the build files and no
      additional work is needed.</p><p>

      ACE has been ported to OpenBSD with and without pthreads
      enabled.  When using pthreads, though, C++ exceptions must be
      disabled.  This is a known problem with the current release of
      OpenBSD (see www.openbsd.org, bug #1750).  ACE emulated
      exceptions work fine.</p><p>

      Compiling TAO may require the user data segment size
      restrictions and possibly other options to be increased.  This
      is done by modifying the default user class in /etc/login.conf
      or by adding a new class and modifying the master passwer file
      accordingly.</p><p>

  </p></li><li><b> UnixWare </b> <p>

      Steve Huston &lt;<a href="mailto:shuston@riverace.com">shuston@riverace.com</a>&gt;

      Building ACE (and TAO) on Unixware 7.1.0 requires a very specific
      g++ build environment.  In particular, you must build and install
      g++ 2.95.2, along with binutils 2.9.1. The order (and the declaration
      of configuration) is extremely important. Using the gcc compiler
      provided on the Skunkware CD on a pentium system, here is the recipe
      I used to build a working environment (as root):<br>
</p><pre>  mkdir /usr/local/newgnu
&lt; ftp and untar binutils-2.9.1 &gt;
&lt; ftp and untar gcc-2.95.2 &gt;
  mkdir -p build/binutils build/gcc
  cd build/binutils
  ../../binutils-2.9.1/configure i386-sco-sysv4
  gmake  # takes a long time
  gmake install # this creates /usr/local/i386-sco-sysv4/...
  mkdir /usr/local/i486-pc-sysv5/bin
  cd /usr/local/i486-pc-sysv5/bin
  for a in /usr/local/i386-sco-sysv4/bin/*; do ln -s $a .; done
  #links all the newly installed utilities

  cd /usr/local/newgnu/build/gcc
  ../../gcc-2.95.2/configure --with-gnu-as --with-gnu-ld
  gmake bootstrap # takes a long time
  gmake install
  mkdir /usr/local/i586-UnixWare7.1.0-sysv5/bin
  for a in /usr/local/i386-sco-sysv4/bin/*; do ln -s $a .; done
</pre>
       Once done, ACE and TAO will successfully build and link.<p>

      5.4 and earlier don't support the C++ features ACE needs.</p><p>

      At this moment <a href="http://www.remedy.nl">Remedy IT</a> is upgrading
      and stabilizing ACE/TAO support for Tornado 2.2/VxWorks 5.5.1.
      Since the existing support for previous VxWorks version has been unsupported
      and broken for some time and most (potential) users seem to have upgraded to
      VxWorks 5.5.1 no backporting effort is done. See also <a href="#vxworks">here</a>.
      </p><p>

      Tornado 2.2/VxWorks 5.5.1 support IP multicast.  That is not enabled
      by default in ACE for VxWorks, because it depends on your
      kernel configuration.  To enable it, add
      <code>#define ACE_HAS_IP_MULTICAST</code> to your
      <code>ace/config.h</code>.</p><p>

      NOTE: In order for the ACE Broadcast and Multicast tests to work the VxWorks kernel
      should receive the packages it sends out locally. By default this is not supported.
      To enable this behaviour you need to include the IFF_SIMPLEX flag for your required
      NIC driver. See the following Windriver <a href="https://secure.windriver.com/cgi-bin/windsurf/techtips/public/viewSum.cgi?4542">SPR 4542</a>
      for more information.</p><p>

      In addition to all of the other benefits of ACE, it helps work
      around some deficiencies with VxWorks. The problems are:</p>

      <p>
      </p><ol>
        <li>The program entry point cannot be called "main" with g++.  ACE
            renames it to "ace_main" (configurable via ACE_MAIN) on VxWorks.
            While this may seem trivial, it is important with legacy code.
            ACE itself ran into this problem.<p>

        </p></li><li>argc/argv isn't used with VxWorks entry points.  ACE provides
            a wrapper function that transparently converts shell command
            line arguments to argc/argv form.  See <a href="#spa">below</a>
            for details.<p>

      </p></li></ol>

      Please note that ACE uses one of the spare fields in the Wind
      River task control block, spare4, for thread-specific storage.
      This field is specified in only one place, in ace/OS_NS_Thread.inl, so it
      can easily be changed to one of the other spare fields, if
      necessary.</p><p>

      ACE destroys dynamically
      allocated singletons in the ACE library.  But, they may not
      properly destroy some static objects.  If you have trouble
      running a program multiple times, it may be necessary to unload
      the module, using unld, and reload it between runs.
      Alternatively, you could try calling <code>cplusDtors</code> and
      then <code>cplusCtors</code> between runs.</p><p>

  </p></li><li><b>MVS OpenEdition</b> <p>

      All of ACE has been ported to OpenEdition by Chuck Gehr &lt;<a href="mailto:gehr@sweng.stortek.com">gehr@sweng.stortek.com</a>&gt;.
      The ACE library, all the tests and most of the examples and apps
      build clean.  There are still some problems that need to be
      ironed out:</p><p>

      MVS does not support the dynamic linking dl...() calls that the
      Service Configurator uses to dynamically link services at run
      time. As a result, all the examples and apps that use a svc.conf
      file (for dynamically configuring service objects) do not work,
      however, most of these apps can be built/run statically.  Also,
      the Svc_Conf_l.cpp and Svc_Conf_y.cpp files are generated using
      flex and yacc on a ascii (not ebcdic) machine and as a result
      they don't work very well with ebcdic svc.conf files.  We should
      be able to regenerate these files on MVS but MVS doesn't have
      flex.  This is something that needs to be done.</p><p>

      Some of the tests do not execute properly.  This is a minority
      and over time the goal is to get to 100%.</p><p>

      The make scheme for some of the apps still doesn't work
      perfectly on MVS.  This is mainly due to the way shared
      libraries are handled on MVS.  See <a href="#mvs">additional
      build tips for MVS</a> for more on this.</p><p>

  </p></li><li><strong>QNX Neutrino</strong><p>

      ACE has been ported to <a href="http://www.qnx.com/products/os/neutrino.html">QNX Neutrino
      2.0</a>.  We cross-compile for Neutrino on a QNX4 host using g++
      2.8.1, using the <a href="ace/config-qnx-neutrino.h">ace/config-qnx-neutrino.h</a>
      and <a href="include/makeinclude/platform_qnx_neutrino.GNU">include/makeinclude/platform_qnx_neutrino.GNU</a>
      configuration files.  Many of the ACE tests succeed, though some
      fail.  As the porting effort progresses, we hope to eliminate
      these failures.  If you know of fixes, please send them to
      us.</p><p>
      </p></li><li><strong>QNX RTP</strong><p>

      ACE has been ported to <a href="http://get.qnx.com/">QNX RTP
      </a>. We compile for QNX RTP using the GCC compiler shipped with the
      distribution, using the <a href="ace/config-qnx-rtp.h">ace/config-qnx-rtp.h</a>
      and <a href="include/makeinclude/platform_qnx_rtp_gcc.GNU">include/makeinclude/platform_qnx_rtp_gcc.GNU</a>
      configuration files.
      Many of the ACE tests succeed, though some
      fail.  As the porting effort progresses, we hope to eliminate
      these failures.  If you know of fixes, please send them to
      us.</p><p>
      <strong><blink><font color="#ff0000">WARNING:</font></blink></strong>
      Under the current version of QNX RTP ACE fails if compiled with
      inline=0 . </p><p>

  </p></li><li><strong><a name="rtems">RTEMS</a></strong><p>

      The support for RTEMS has been reviVed from version x.5.4. This version
      was the first version that build again out of the box on RTEMS. Compilation
      and testing was done for RTEMS with and without networking support. The
      ACE GNU makefiles do automatically detect whether networking support
      is available or not.

      Besides the standard config.h/platform_macros.GNU file you will need
      to set <code>RTEMS_MAKEFILE_PATH</code> to point to the location
      of your RTEMS installation, see below for an example.</p>
      <p><code>export RTEMS_MAKEFILE_PATH=/opt/rtems/CPU-rtems/BSP</code></p>
      <p>
      When building without network support you will need the ace_for_tao
      subsetting functionality enabled. For this add <code>ace_for_tao = 1</code>
      to your <code>bin/MakeProjectCreator/config</code> file and regenerate the
      GNU makefiles as described <a href="#power">here</a>.</p><p>

  </p></li><li><strong>PharLap ETS</strong><p>

      ACE has been ported to Ardence's
      <a href="http://www.ardence.com/embedded/products.aspx?ID=71">PharLap ETS</a>
      version 13. The port was originally done for Pharlap 9.1 and MSVC 6,
      but has been updated to Pharlap ETS 13 with Visual Studio .NET 2003
      (VC7.1).</p><p> To build for PharLap, you'll need to use MPC to
      generate .sln/.vcproj files with the ETS configurations. For example:
      <pre>
cd \ace\ACE_wrappers
perl bin/mwc.pl  -type vc71 -relative ACE_ROOT=C:/ace/ACE_wrappers -relative TAO_ROOT=C:/ace/ACE_wrappers/TAO -value_template configurations='"ETS Debug"' -value_template configurations+='"ETS Release"' -name_modifier *_ETS TAO_ACE.mwc
      </pre>
      That command will generate the same .sln and .vproj files as for
      regular Windows builds with VC7.1, but they'll have names with an
      <code>_ETS</code> suffix and will include the "ETS Debug" and
      "ETS Release" configurations.</p><p>
      After generating the needed VC7.1 files, use the ace/config-pharlap.h
      configuration file, and the instructions
      for building on Windows. Building the ACE library is the same as
      for regular Windows platforms, except you choose one of the PharLap
      ETS configurations to build within Visual Studio.
      For an example of how to build binaries, see the tests directory.
      The tests_pharlap_msvc.lnk file is a LinkLoc commands file that the
      ACE tests are built with. It is likely that local sites may need
      to adjust this file for their target environment.
      </p><p>
      When executing programs on the target system, it is possible that not
      all of the VC++ support DLLs are resident on the target. In particular,
      the debug-supporting DLLs may not be present. If you require these, be
      sure to add those needed. For example, on the standard LabVIEW RT 8.2
      distribution using Pharlap ETS, the following DLLs must be copied to
      the target before being able to run Debug programs:
      <ul>
        <li>msvcp71d.dll</li>
        <li>msvcr71d.dll</li>
      </ul>
      </p><p>
      <note>To build ACE for National Instruments' LabVIEW RT, use
      the Pharlap ETS information above, but add the following line to your
      config.h file:
      <pre>
      #define ACE_PHARLAP_LABVIEW_RT
      </pre>
      This setting makes the necessary adjustments for LabVIEW's implementation
      of Pharlap ETS.</note>

      <note>By default, the ACE tests log their output/results to the
      system console on Pharlap ETS. To change this behavior and make the
      test output log to a file in the <code>log</code> directory under the
      current working directory while executing, add the following line to
      your config.h file:
      <pre>
      #define ACE_PHARLAP_TESTLOG_TO_FILE
      </pre>
      This setting has no affect on TAO tests which always write test output
      to stdout.
      </note>

</p></li><li><strong>Mac OS X (10.2.x)</strong><p>

        </p><p>ACE builds and runs on Mac OS X 10.2.x, but the following are
        needed to build it:</p>

        <p>1. The latest version of the Apple Developer Tools
        (December 2002)</p>
        <p>2. The dlcompat library (obtained either through Fink or
        SourceForge)</p>

        <p>When creating $ACE_ROOT/ace/config.h for Mac OS X, you need
        to add the following if you obtained dlcompat via Fink:</p>

        <p>#define ACE_NEEDS_DL_UNDERSCORE</p>

        <p>You'll also need to do:</p>

        <p>setenv DYLD_LIBRARY_PATH $ACE_ROOT/ace:$ACE_ROOT/lib</p>
        <p>setenv MACOSX_DEPLOYMENT_TARGET 10.2</p>

        <p>Currently, all ACE tests pass except Process_Mutex_Test and
        MEM_Stream_Test.  Also, Mac OS X doesn't yet support *nix
        aio_* calls, and ACE does not know anything about Mach.</p>

        <p>The work to port ACE to Mac OS X was done by several people,
        John Zorko
        &lt;<a href="mailto:j.zorko@att.net">j.zorko@att.net</a>&gt; is
        only one of them.</p>

</p></li><li><strong>iPhone/iPod Touch/iPad</strong><p>

        </p><p>ACE builds and runs on the iPhone/iPod Touch/iPad Hardware
        and Simulator. Keep in mind that ACE/TAO needs to be built
        statically since Apple does not allow third party dynamic libraries
        to be deployed on the hardware. The following are needed to build ACE:</p>

        <p>1. The iPhone SDK.</p>
        <p>2. When creating $ACE_ROOT/ace/config.h, include
        config-macosx-iphone-hardware.h if you want to deploy on the
        hardware, include config-macosx-iphone-simulator.h if you want
        to deploy on the simulator. Even though those includes are named
        after the iPhone, the includes work for iPhone/iPod Touch, and iPad.</p>
        <p>3. You need to define two environment variables. The first is
        IPHONE_TARGET. Set IPHONE_TARGET to SIMULATOR if you want to deploy
        on SIMULATOR. Set IPHONE_TARGET to HARDWARE if you want to deploy on
        the hardware device.</p>
        <p>4. When creating $ACE_ROOT/include/makeinclude/platform_macros.GNU,
        include 'include $(ACE_ROOT)/include/makeinclude/platform_macosx_iphone.GNU'
        in the file.</p>



</li></ul>


<hr>
<h2><a name="g++">Compiling ACE with GNU g++</a></h2>

If you use the GNU GCC g++ compiler please note the following:

<ul>
  </p></li><li>ACE/TAO needs g++ 2.95.x or better. Older versions are not usable anymore<p>

  </p></li><li>Make sure to update your gcc <code>config.status</code>
      file.  This file is produced when installing gcc; it specifies
      where to install the binary files that gcc uses.  For example,
      it specifies whether to use Solaris's <code>/usr/ccs/bin</code>
      binary utils or GNU binary utils.  The
      <code>config.status</code> file is an output of the gcc
      <code>configure</code> script; it is preferable to use the
      <code>--prefix</code> option to <code>configure</code> instead
      of hacking its output.<p>

  </p></li><li>If you are getting weird link errors when building libACE
      on Solaris you are probably using the GNU linker.  Try using the
      Sun linker (/usr/ccs/bin/ld) instead.  Note that gcc first looks
      for the GNU linker if it is installed along with gcc.  The only
      way to not use the GNU linker is to delete it from the
      installation or to build your own compiler with no linker.  Be
      aware that you still need the libraries and includes of gcc.<p>

      NOTE: if you do use the GNU linker, you might need to change
      the <code>-G</code> flag to <code>-shared</code> in
      the <code>SOFLAGS</code> definition in your
      <code>include/makeinclude/platform_macros.GNU</code>.</p><p>

  </p></li><li>Don't get too confused about contradictory statements in
      the gcc documentation. It was written by different
      people...<p>

  </p></li><li>Make sure that the linker invoked by gcc produces code
      that initializes static objects.  Please see gcc's
      documentation for using <code>collect2</code>.<p>

</p></li></ul>

</p><h2><a name="minimum_build">What Do I Need to Build for TAO?</a></h2>
Toshio Hori &lt;toshi@etl.go.jp&gt; provided these suggestions on building
just what's needed for (a subset of) TAO:<p>

I usually make:
</p><pre>    $ACE_ROOT/ace,
    $ACE_ROOT/apps/gperf,
    $TAO_ROOT/tao,
    $TAO_ROOT/TAO_IDL, and
    $TAO_ROOT/orbsvcs/orbsvcs
</pre>
and the whole make takes less than an hour on my Solaris 7 for intel,
Pentium-III/550MHz, 256MB memory, 512MB swap machine.  (Top secret: I
renice the 'make' process to the highest priority, -20... ;-)

To save time and space, I set
<pre>    TAO_ORBSVCS = Naming Time Trader ImplRepo
</pre>
in <code>$ACE_ROOT/include/makeinclude/platform_macros.GNU</code> also.  See
<a href="TAO/docs/configurations.html#orbsvcs">TAO's orbsvcs
library customization instructions</a> for more information.<p>


</p><hr><p> </p><h2><a name="resource_requirements">System Resource
Requirements</a></h2> The amount of system resources required to build
ACE and TAO varies greatly.  The required system resources are
influenced by OS and compiler platform, build options, and component
configurations.  As a rough guide, the typical peak memory requirement
can be well over 512 MB (notably, for TAO's orbsvcs).  Depending on
your OS and compiler configuration, an <strong>entire</strong> build
of ACE and TAO can use well over 4 GB of disk space.  It's usually not
necessary to build <strong>all</strong> of ACE and TAO, though.<p>

Much less disk space is required for just the libraries.  For example,
see the <a href="docs/ACE-subsets.html#ACE%20Library%20Size%20Breakdown">ACE
library subset sizes</a>.</p><p>

If you run out of memory when building, you might consider trying
some or all of these suggestions:</p><p>
</p><ul>
  <li>Enable or increase virtual memory.  If you're on a <a href="#Linux">Linux</a> or <a href="#LynxOS">LynxOS</a> platform,
    please see the appropriate sections above.<p>
  </p></li><li>Disable/enable optimization and/or debugging.  See the
    <a href="#flags">Makefile Flags</a> discussion for information
    on how to do that via ACE's Makefiles.<p>
  </p></li><li>If you're using g++, try removing <code>-pipe</code> from
    <code>CFLAGS</code> in your
    <code>include/makeinclude/platform_macros.GNU</code> file.<p>
  </p></li><li>Restrict the components that you build.  For ACE and TAO, see the
    discussion of <code>ACE_COMPONENTS</code> in the
    <a href="docs/ACE-subsets.html">ACE subsets</a> page.  For TAO's
    orbsvcs, see the discussion of <code>TAO_ORBSVCS</code> in
    <a href="TAO/docs/configurations.html#orbsvcs">orbsvcs Library configuration information</a>.<p>

If disk space is a problem, disabling debugging should greatly
reduce object code, and therefore, library size.  This is especially
true with g++.</p><p>

Toshio Hori &lt;toshi@etl.go.jp&gt; provided these tips for reducing
disk space usage:</p><p>

To save space on a Unix machine, I usually run
    'find . -name \*.sln -o -name \*.vcproj -o -name \*.bmak | xargs rm -f'
in $ACE_ROOT at first after I untar the distribution.  They are
meaningless in my environment (Files named '*.sln' and '*.vcproj' are
used for MSVC++ and files named '*.bmak' are for Embarcadero C++
Builder.)</p><p>

Finally, to save space, may want to run 'make clean' after 'make'.  It
removes generated object files and leaves libraries/executables
intact.  If you want to remove any of the libraries/executables, as
well, try 'make realclean'.</p><p>

The <A HREF="
http://downloads.ociweb.com/MPC/docs/html/MakeProjectCreator.html</A>
Makefile Project Creator (MPC)</A> is a tool that takes platform and
building tool generic files (mpc files) as input, which describe basic
information needed to generate a "project" file for various build
tools, including Make, NMake, Visual C++ 6, Visual C++ 7, etc.  Please
see <a href="MPC/docs/USAGE">USAGE</a>, <a
href="MPC/docs/README">README</a> for documentation on MPC.<P>

A common usage for creating a Windows workspace containing just the
core ACE and TAO libraries and executables is the following:

<pre><code>
C:> cd %TAO_ROOT%
C:> %ACE_ROOT%\bin\mwc.pl -type vc71 TAO_ACE.mwc
</pre></code>

Replace vc71 with whatever project type you want to use.  On Linux and
other UNIX platform use the gnuace type: <P>

<pre><code>
% cd $TAO_ROOT
% $ACE_ROOT/bin/mwc.pl -type gnuace TAO_ACE.mwc
</pre></code>

this creates the appropriate GNUmakefiles.  Additional information on
how to obtain, configuration, and build ACE+TAO using MPC appear at
the OCI <A
HREF="http://www.theaceorb.com/faq/index.html#HowToBuildACEandTAOonWindows">FAQ</A>.<P>

If you are attempting to generate project files using MPC, and you get
the following error message:<br>

<pre>ERROR: Unable to find the MPC modules in /builds/ACE_wrappers/MPC.
You can set the MPC_ROOT environment variable to the location of MPC.
</pre>

You need to do one of the following:

<ol>
<li>If you have already obtained MPC, either move it underneath the

defined in the distributed ACE <code>config.h</code> headers for
VxWorks and Win32.</p><p>

The important requirement is that the program <strong>must</strong>
declare its <code>main</code> function with two arguments, even if
they're not used, and with <code>int</code> return type:

</p><pre><code>
int
main (int, char *[])
</code></pre>

If you don't declare <code>main</code> <strong>exactly</strong> that
way, then you'll see a link error about <code>ace_main_i</code> being
undefined.<p>

Alternatively, this feature can be disabled by commenting out the
#define ACE_HAS_NONSTATIC_OBJECT_MANAGER in the
<code>ace/config.h</code>.  But, that will make repeated testing more
difficult on VxWorks.  And, you'd either have to call static
constructors and destructors manually or unload/load the program
between runs.  On Win32, disabling the feature can possibly lead to
shutdown difficulties.</p><p>

<strong><blink><font color="#ff0000">WARNING:</font></blink></strong>
<code>ACE_HAS_NONSTATIC_OBJECT_MANAGER</code> assumes that your
<code>main</code> function is named <code>main</code>.  Any violation
of this assumption is at your peril.  If you really need to call your
entry point something other than <code>main</code>, you'll need to
construct and destroy the ACE_Object_Manager.  The best way to do that
is to call <code>ACE::init ()</code> and <code>ACE::fini ()</code>.
Or, see the <code>#define</code> of <code>main (int, char *[])</code>
in <a href="ace/OS_main.h"><code>ace/OS_main.h</code></a> to see how ACE does
that for entry points named <code>main</code>.

</p><h2><a name="cloning">Cloning the Source Tree</a></h2>

On UNIX platforms, we typically like to support multiple platform
builds using the same ACE source tree.  This idiom is supported by ACE
using the $ACE_ROOT/bin/create_ace_build.pl script.

To clone the source tree, create ./build and ./build/{your build name}
subdirectories under the ACE_wrappers directory.
Then invoke the create_ace_build.pl script to clone the source tree using
soft links from your build directory back to the actual sources.
Here is an example:</p><p>

</p><pre>% cd ACE_wrappers
% mkdir build build/build-SunOS5
% perl bin/create_ace_build.pl -a -v build-SunOS5
% cd build/build-SunOS5
% setenv ACE_ROOT $cwd
% make
</pre><p>

This will establish a complete tree of links.  In addition, make sure
you set your <code>LD_LIBRARY_PATH</code> to
<code>$ACE_ROOT/lib:$LD_LIBRARY_PATH</code> on SVR4 UNIX
platforms.</p><p>

When you do a make in the $ACE_ROOT directory you will be producing
object code that is not stored in the same place as the original
source tree.  This way, you can easily build another platform in a
parallel tree structure.</p><p>

See the comments at the top of the create_ace_build.pl script for
further usage information.

</p><h2><a name="mvs">Additional Build Tips for MVS</a></h2>

For all intents and purpose, MVS OpenEdition (OE) is another flavor of
UNIX, therefore, the instructions under <a href="#aceinstall">Building
and Installing ACE on Unix</a> can be used along with the following
additional tips:<p>

You can get a copy of GNU make that has been ported to MVS OpenEdition from
the <a href="http://www.s390.ibm.com/products/oe/index.html">IBM OpenEdition web site</a>.
ACE's make scheme generates compile commands that have options and
operands interspersed.  By default, the c89/cc/c++ compiler expects all options to
precede all operands.  To get around this, you must set a special
compiler environment variable (_CXX_CCMODE) to 1 which tells the compiler
to allow options and operands to be interspersed.</p><p>

Note that the environment variable <code>LD_LIBRARY_PATH</code> is
called <code>LIBPATH</code> on MVS.</p><p>

Shared objects are built a little different on MVS than on
other UNIX implementations.  This has been accounted for in the makefiles
that come with ACE   When the linker (via the cxx command) builds the
libACE.so file it will also create a file called libACE.x.  This is a
side-deck file and it must be included in subsequent link edits with
application code.  For more information on this see the C/C++ MVS
Programming Guide.  If you want to build your application statically,
i.e., using libACE.a instead of libACE.so, you can set ACELIB to
ACELIB_STATIC in platform_mvs.GNU.</p><p>

When the libACE.so file is built (via the MVS pre-linker and binder), you
will get a rc=4 from the pre-linker.  This is ok.  This is due to some
warnings about unresolved references which should get resolved during the
link step.  Note, however, there shouldn't be any unresolved references
from the binder (linkage editor).   You can get pre-link and link maps by
uncommenting the PMAP and LMAP lines in the platform_mvs.GNU file.

</p><p></p><hr align="left" width="50%"><p>
</p><h2><a name="flags">Makefile Flags</a></h2>

GNU make provides many options to customize its operation.  See its
documentation for more information.  One example is that for multi-cpu
UNIX machines you will be able to build faster if you use:<p>

</p><pre><code>
% make -j <em>n</em>
</code></pre><p>

which allows parallel compilation. The number <i>n</i> should
typically be the number of CPUs.  It is likely that builds will be
faster even on single-CPU UNIX machines with <code>make -j
2</code>.</p><p>

ACE further supports the following flags.  They can be enabled either
on the command line, e.g., "make purify=1", or added to your
<code>platform_macros.GNU</code>.  To disable the option,
set the flag to null,
e.g., "make debug=".  Some flags support setting to 0 disable, e.g.,
"make debug=0".  debug=1 is enabled in the platform files that are
released with ACE.</p><p>

Please note that the effects of a flag may be platform specific.
Also, combinations of certain flags may or may not be allowed on
specific platforms, e.g., debug=1 opt=1 is supported by g++ but
not all other C++ compilers.</p><p>

If you use Purify or Quantify:  purify or quantify <strong>must</strong>
be on your <code>PATH</code>.  By default, ACE puts the Purify/Quantify
caches below <code>/tmp</code>.  To override that, set the
<code>PURE_CACHE_BASE_DIR</code> variable, either in your environment
or on the <code>make</code> make command line, to the destination
directory for your instrumented libraries.</p><p>

</p><pre>Flag             Description
----             -----------
debug            Enable debugging; see DCFLAGS and DCCFLAGS.
exceptions       Enable exception handling (not supported by all platforms).
include_env      Support old-style ACE_TRY_ENV declarations in methods.
                 This switch is necessary for compiling TAO applications
                 in the native exception configuration that were written
                 for TAO versions before 1.2.2.
                 In TAO 1.2.2, new macros were introduced that supercede
                 the direct ACE_TRY_ENV declarations. These are the
                 ACE_ENV_ARG macros that are defined in ace/CORBA_macros.h
                 and are documented in docs/exceptions.html.
                 This switch only affects the exceptions=1 configuration.
                 It is for backward compatibility only.
                 There will be warnings about unused _ACE_environment_variable
                 parameters when using include_env=1.
                 If possible, do not use it, but instead change your TAO
                 applications to use the ACE_ENV_ARG macros.
fast             Enable -fast option, e.g., with Sun C++.
inline           Enable ACE inlining.  Some platforms enable inlining by
                   default, others do not.
optimize         Enable optimization; see OCFLAGS and OCCFLAGS.
pace             Enable PACE as the underpinnings of ACE_OS.
probe            Enable ACE_Timeprobes.
profile          Enable profiling; see PCFLAGS and PCCFLAGS.
purify           Purify all executables.
quantify         Quantify all executables.
repo             Use GNU template repository (g++ with repo patches only).
rtti             Enable run-time type identification.  On some platforms,
                   it is enabled by default, so this is ignored.
shared_libs      If migrating from prior version use <code>shared_libs_only</code>
static_libs      If migrating from prior version use <code>static_libs_only</code>
shared_libs_only Only build shared libraries.  Ignored if no SHLIBs are
                   specified by the Makefile, as in performance-tests/Misc.
static_libs_only Only build static libraries.
threads          Build with thread support.
xt               Build with Xt (X11 Toolkit) support.
fl               Build with FlTk (Fast Light Toolkit) support.
tk               Build with Tk (Tcl/Tk) support.
qt               Build with Qt (Trolltech Qt) support.
ssl              Build with OpenSSL support.
rapi             Build with RAPI
split            Build the library by first splitting up the ACE source
                   to several files, with one object code entity for each
                   source file. This allows an application that is linked
                   with ACE to extract _exactly_ what it needs from the
                   library, resulting in a smaller executable.  Setting this
                   to 1 overrides debug to 0.

Usually, users do not need to be concerned with make targets.
Just enter "make" on the command line to build.  A few notable
targets are listed below.

Target             Description
------             -----------
show_statics       Lists all static objects in object files built for
                     current directory.  Only supported for g++.
show_uninit        Lists all uninitialized in object files built for
                     current directory.  Only supported for g++.
