Installation instructions for supported platforms

  Assumptions

   These installation instructions assume that you are building from
   sources obtained from [5]http://www.flaterco.com/xtide/files.html.
   However, some Linux users may be able to shortcut this process:  XTide
   has been included in [6]Fedora and [7]Debian.  (Thanks to the relevant
   package maintainers.)

   These instructions also assume that you are building XTide version
   2.9.  Previous versions of XTide were not packaged with [8]GNU
   automake, so the installation process was not as standardized.  In
   addition, they statically linked with an included version of libtcd
   instead of using a shared libtcd that was installed separately.  For
   these reasons and others it is advisable that you upgrade to XTide 2.9.

  Dependencies

   In addition to the minimal set of X11 libraries that pretty much
   everyone has, you need the following libraries:

     * [9]libXpm 3.4 or newer compatible version
     * [10]libpng version 0.96 or newer compatible version
     * [11]zlib (a.k.a. libz) version 1.0.4 or newer compatible version
     * [12]libtcd version 2.2 or newer compatible version

   XTide 2.9 will link with [13]libdstr (version 20070215 or compatible)
   if it is found on the system, but installing it is completely
   optional.  If it is not present, XTide will link statically with a
   bundled copy of Dstr.

   tide and xttpd can be compiled in the absence of X11 libraries and
   libXpm.  However, you still need the other stuff.

  Downloading

   Mandatory:  You need the XTide source code distribution, available in
   bzipped tar format at
   [14]http://www.flaterco.com/xtide/files.html#xtide.

   Mandatory:  You need at least one harmonics file.  Harmonics files
   contain the data that are required for XTide to predict tides for
   different locations.  Canonical harmonics files and information on
   getting others is provided at
   [15]http://www.flaterco.com/xtide/files.html#harmonicsfiles.

   Optional:  If you want to enable XTide to draw coastlines on the map,
   you will also have to download the World Vector Shoreline (WVS) files,
   which are available in bzipped tar format at
   [16]http://www.flaterco.com/xtide/files.html#WVS.

   WVS is optional because the minimum recommended hardware (166 MHz
   Pentium PC) takes 16 seconds to draw shorelines for a hemisphere of the
   globe.  A 3.2 GHz P4 takes less than 1 second.

  Installing a harmonics file

   First you need to decompress it.  You can use the command-line tool
   [17]bzip2 as shown below, or you can use [18]7-Zip or any other
   archiver that supports the bzip2 format.

bzip2 -d harmonics-dwf-YYYYMMDD-free.tcd.bz2

   Then move the uncompressed TCD file to a permanent location, e.g.,
   /usr/local/share/xtide, and make it world readable:

mkdir /usr/local/share/xtide
chmod 755 /usr/local/share/xtide
chmod 644 harmonics-dwf-YYYYMMDD-free.tcd
mv harmonics-dwf-YYYYMMDD-free.tcd /usr/local/share/xtide

  Installing the World Vector Shoreline files (optional)

    1. Create a directory to contain the WVS files.
    2. Change your current working directory to that directory.
    3. Unpack the tar file in that directory.

   Under Linux and any other system with GNU tar:

tar xvjf wvs.tar.bz2

   Elsewhere:

bzip2 -dc wvs.tar.bz2 | tar xvf -

  Unpacking the sources

   Under Linux and any other system with GNU tar:

tar xvjf xtide-2.xyz.tar.bz2

   Elsewhere:

bzip2 -dc xtide-2.xyz.tar.bz2 | tar xvf -

  Configuring

    I.  Specify the location of the harmonics file(s)

   There are two ways to do this.

    1. The first way is by setting the environment variable HFILE_PATH.

export HFILE_PATH=/usr/local/share/xtide/harmonics.tcd

       In the event that you have more than one harmonics file that you
       wish to use simultaneously, list them separated by colons.

export HFILE_PATH=/usr/local/share/xtide/harmonics-free.tcd:/usr/local/share/xti
de/harmonics-nonfree.tcd

       Alternately, make sure that they are by themselves in a special
       directory and specify that directory as the value of HFILE_PATH.
       If an element of HFILE_PATH is a directory, XTide will attempt to
       load every file in that directory (so be sure that they are all
       harmonics files!)
       If you are installing as root, then it is recommended that you add
       this definition to a system-wide script such as /etc/profile if you
       have one.
    2. The other way is by creating the file /etc/xtide.conf.  The
       environment variable, if set, takes precedence over the config
       file.
       If a configuration file is used, the first line should consist of
       the value that would be assigned to HFILE_PATH:
/usr/local/share/xtide/harmonics-free.tcd:/usr/local/share/xtide/harmonics-nonfr
ee.tcd

    II.  Specify the location of the World Vector Shoreline files (optional)

   Either set the environment variable WVS_DIR to the name of that
   directory or supply the directory name as the second line of the
   configuration file /etc/xtide.conf.

    III.  Run the configure script

bash-3.1$ ./configure

   XTide 2.9 is packaged with the popular and portable [19]GNU automake,
   so all usual GNU tricks should work.  Help on configuration options can
   be found in the CONFIGURE-HELP file or obtained by entering ./configure
   --help.

   The web server xttpd is not necessary to use tide or xtide, so most
   users needn't worry about it.  However, if you plan to run it, there is
   additional configuration at this point.

   To change the user and/or group under which xttpd tries to run (the
   defaults are nobody/nobody), provide the options --with-xttpd-user=user
   and/or --with-xttpd-group=group to configure.  If you want to run xttpd
   but you don't have root, you will have to set these to your own
   username and the name of some group to which you belong.

bash-3.1$ ./configure --with-xttpd-user=xttpd --with-xttpd-group==scarydmons

   You can also set the webmaster address for xttpd this way.

bash-3.1$ ./configure --with-webmaster="somebody@somewehere.else"

    IV.  Other optional and alternative configurables

   --enable-time-workaround Work around Y2038 problem; disable time
   zones.  See [20]Appendix A -- Historical predictions and Y2038
   compliance.
   --enable-gnu-attributes Use with g++ -Wall -Wextra to make warnings
   smarter.
   --enable-semicolon-pathsep Use ; instead of : to separate names in
   HFILE_PATH (good idea if they begin with C:\)
   --enable-local-files Locate xtide.conf, .xtide.xml, and
   .disableXTidedisclaimer files in current working directory

   You can change the compile-time defaults (colors, etc.) set in
   config.hh if you so choose.  However, the easiest way to set all of
   those things is with the [21]control panel in the interactive XTide
   program.

   The e-mail address for feedback in xttpd can also be changed by setting
   the environment variable XTTPD_FEEDBACK, in lieu of the configure
   option mentioned above.

  Compiling

bash-3.1$ make
bash-3.1$ su
bash-3.1# make install

Special cases

  Don't have X11

   If you don't have any version of X11 installed and just want to compile
   xttpd or tide, generate a Makefile using ./configure and then type
   'make xttpd' or 'make tide'.  You will probably need to install the
   binaries by hand.

  CPU-bound platform

   If running on the minimum recommended hardware (166 MHz Pentium PC) it
   is advisable to forego installing the [22]World Vector Shoreline
   database.  If a true color display is present, graph drawing can be
   sped up enormously by turning off anti-aliasing (see [23]settings,
   XTide*antialias).

  Cygwin

  XTide can be compiled and run using [24]Cygwin, which is an emulated Unix
  environment for Windows that is free for typical non-commercial users.  The
  Cygwin distribution and its full license terms are available from
  [25]http://www.cygwin.com/.

  Cygwin packages are all versioned separately, so there is no baseline "Cygwin
  version" against which to test XTide.  Testing was most recently performed
  with XTide 2.9.2 using the collection of packages that was current as of
  2007-03-31.

  As of then, the quirks apparent after brief testing were as follows.

    1. If only building certain of the programs, you must type (e.g.)
       'make tide.exe' instead of 'make tide'.  'make tide' causes the
       automake-generated makefile to do something silly.
    2. Graph drawing in the interactive interface is an order of magnitude
       slower.  The slowdown can be mitigated by turning off anti-aliasing
       (see [26]settings, XTide*antialias).
    3. When you drag a window around, fine-grained exposure events for any
       overlapped windows are queued but not delivered until you drop it.
       The resulting redraw behavior is suboptimal.
    4. When you resize a graph window, instead of delivering one
       ConfigureNotify event, Cygwin delivers a huge pile forming a
       continuum between the old size and the new one.^[27]1  This is
       worse than suboptimal as it can take a long time to resize the
       graph that many times.  Once again, the slowdown can be mitigated
       by turning off anti-aliasing (see [28]settings, XTide*antialias).

   Cygwin used to have worse problems than that, so it is highly advisable
   to update your installation before compiling XTide.

  Mac OS X

  XTide version 2.9.5 or newer should compile cleanly and run under Mac OS
  10.3.3 or later.

  If the PNG package is installed via Fink ([29]http://fink.sourceforge.net/),
  use CPPFLAGS="-I/sw/include" and LDFLAGS="-L/sw/lib" to find the
  Fink-installed PNG files.

  A [30]native port to OS X is also available.
  IRIX

  Some SGI machines come with a broken make program.  Use GNU make.
  HP-UX

  Long ago, a user submitted the following flags to get XTide to compile using
  the aCC compiler under HP-UX.  If somebody still uses this platform and the
  flags are still needed, they can be supplied to configure:

bash-3.1$ CXX="aCC" CXXFLAGS="-Wc,-koenig_lookup,on +DAportable" LDFLAGS="-lPW"
./configure

   It is possible that the latest configuration scripts add all needed
   flags automatically, but they have not been tested under HP-UX.

  Visual C++ Express Edition

  A native Windows binary for the command-line client tide can be built using
  Visual C++ Express Edition (either 2005 or 2008).  However, you will still
  need a [31]Cygwin environment to run the build process.  GCC is not required,
  but you'll need the bash shell, GNU make, etc.

  Visual C++ ignores most of the standard command-line switches that the build
  process tries to use.  These instructions include a minimal set of workarounds
  so that tide will compile anyway.  However, because of the basic
  incompatibilities, you will still get a lot of warnings.

  Before attempting to run configure or make, the environment variables PATH,
  INCLUDE, and LIB must be set to cover (A) the Visual C++ environment itself
  and (B) your installations of [32]libpng, [33]zlib and [34]libtcd native
  Windows libraries.

  To set variables for Visual C++, Visual C++ provides a batch file called
  vsvars32.bat that can be found somewhere in the Visual C++ program folder
  (e.g., C:\Program Files\Microsoft Visual Studio
  9.0\Common7\Tools\vsvars32.bat).  To get these settings into the Cygwin
  environment, follow these three steps:

    1. Start a Command Prompt (Start->Accessories->Command Prompt or run
       cmd.exe).
    2. At the command prompt, invoke vsvars32.bat (use Search to find it
       if necessary).
    3. At the command prompt, invoke cygwin.bat (use Search to find it if
       necessary).

   At that point you should have a bash prompt, and Visual C++ should
   work.  You can add the directories for your [35]libpng, [36]zlib and
   [37]libtcd library installations using bash commands, e.g.,

export LIB="${LIB};C:\\FunkyLibs\\lib"
export INCLUDE="${INCLUDE};C:\\FunkyLibs\\include"

   Having done that, run the configure script like this:

bash-3.1$ ./configure CC=cl CXX=cl LD=cl CPP="cl /E" LDFLAGS="zdll.lib libpng.li
b libtcd.lib" --enable-semicolon-pathsep --enable-local-files

   Depending on how you compiled your [38]libpng, [39]zlib and [40]libtcd
   libraries, the specific file names to be listed in LDFLAGS may be
   different.

   If you get a pop-up saying that "conftest.exe has encountered a
   problem," keep clicking on "Don't Send" until configuration proceeds.
   Then run 'make tide.exe'.  You will get a lot of warnings.  The
   resulting executable might not work from the Cygwin bash prompt but it
   should work when run from a Windows command prompt (DOS box).

   In accordance with the selected configure options, the following
   behaviors will differ from the default Unix behaviors:

     * File names in the environment variable HFILE_PATH or the
       configuration file xtide.conf should be separated by semicolons
       instead of colons.
     * The file xtide.conf (and any other configuration files that you
       use) should go in the current working directory.

   So for example you could put the following in an xtide.conf file in the
   current working directory:

C:\Documents and Settings\Mumble\Foo\harmonics-free.tcd;C:\Documents and Setting
s\Mumble\Foo\harmonics-nonfree.tcd

Troubleshooting

Q: Trying to compile tide using Visual C++, the configure script complains that
it can't find a library, and the following error messages appear in config.log.
Alternately, these errors can occur when linking tide.exe.

MSVCRT.lib(MSVCR80.dll) : error LNK2005: _malloc already defined in LIBCMT.lib(m
alloc.obj)
MSVCRT.lib(MSVCR80.dll) : error LNK2005: _free already defined in LIBCMT.lib(fre
e.obj)
LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; us
e /NODEFAULTLIB:library
conftest.exe : fatal error LNK1169: one or more multiply defined symbols found

   A: These errors occur when libraries are compiled with conflicting
   settings of the Visual C++ compiler switches /MT, /MD and /LD.  Try
   recompiling the libraries without using any such switches.

   Q: tide.exe compiles and runs with Visual C++ 2003, but non-ASCII
   characters (degrees symbol, accented characters, etc.) are not output
   correctly.

   A: This is why Visual C++ 2003 is unsupported.  The function that is
   needed to select a codeset other than the default MS-DOS legacy codeset
   does not work.  Use 2005 or 2008 instead.

   Q: Trying to compile XTide 2.9.4 or earlier on a Mac or Windows file
   system, the configure script crashes immediately.

   A: This is fixed in XTide 2.9.5.  XTide 2.9.4 and earlier did not
   anticipate case-insensitive file systems..

   Q: XTide compiles, but when I try to run it I get an error like
error while loading shared libraries: libtcd.so.0: cannot open shared object fil
e: No such file or directory

   A: Somehow, g++ found the shared library but your dynamic linker
   didn't.  To get the dynamic linker to find the library, you can just
   add its directory to the environment variable LD_LIBRARY_PATH.  For
   example, if you find the library in /usr/local/lib, you would add this
   to your .bashrc (if using bash):
export LD_LIBRARY_PATH=/usr/local/lib

   Or you would add this to your .cshrc (if using csh or tcsh):
setenv LD_LIBRARY_PATH /usr/local/lib

   Q: Trying to compile XTide 2.9.3 using Sun compilers, the following
   error occurs:
"/opt/SUNWspro/prod/include/CC/Cstd/./map", line 251: Error: Multiple declaratio
n for std::map<const Dstr, Configurable, std::less<const Dstr>, std::allocator<s
td::pair<const Dstr, Configurable>>>::insert(const std::pair<const Dstr, Configu
rable>&).
"BetterMap.hh", line 28:     Where: While specializing "std::map<const Dstr, Con
figurable, std::less<const Dstr>, std::allocator<std::pair<const Dstr, Configura
ble>>>".
"BetterMap.hh", line 28:     Where: Specialized in BetterMap<const Dstr, Configu
rable>.
"Settings.hh", line 30:     Where: Specialized in non-template code.

   A: This problem was reported on 2007-04-30 but the cause is still under
   investigation.  One can work around by compiling with g++ instead, but
   if this error is attributable to non-compliant C++ code in XTide I
   would like to fix it.  I do not personally have access to a Solaris
   platform to debug this, so please e-mail any relevant information or
   patches.

   Q: XTide 2.8.3 or earlier compiles, but when run the following error
   occurs:
X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  45 (X_OpenFont)

   A: You need to install the Schumacher fonts.  These fonts were reliably
   present on every X11 installation until 2006, when Linux distributions
   started breaking fonts out into lots of separate packages in accordance
   with upstream advice.  For what it's worth, XTide 2.9 gives a more
   helpful error message that tells you which font it could not load.

   Q: When compiling XTide, I get an error involving xml-something or
   lex.xml.c.

   A: For XTide 2.9 or later, do make xmlclean and then try again.  For
   XTide 2.8.3 or earlier, run the script do_xml.sh and then try again.

   ^1 The Xlib Programming Manual says the ConfigureNotify event is to be
   generated when the resize request "actually completes."  Unlike Expose
   events, there is no mechanism for handling consecutive ConfigureNotify
   events as a batch.  This suggests that the Cygwin interpretation is not
   what was intended.
