wxWindows 2.0 for Motif installation
------------------------------------
IMPORTANT NOTE: If you experience problems installing, please
re-read this instructions and other related files (todo.txt,
bugs.txt etc.) carefully before mailing wxwin-users or
the author. Preferably, try to fix the problem first and
then send a patch to the author.
- Prerequisites: Motif 1.2 or above, or Lesstif
(not yet tested). Motif 2.0 and above may also be suitable.
- Download the files wx200gen.zip and wx200mot.zip, and
documentation in a preferred format, such as wx200htm.zip
or wx200pdf.zip.
- Make a directory such as ~/wx and unzip the files into this
directory. Use the -a option if available to convert the ASCII
files to Unix format. Don't worry about files being
overwritten: they should be identical anyway.
(See http://www.cdrom.com/pub/infozip/ if you don't have zip/unzip
already installed. Zip isn't the same as gzip!)
- It is recommended that you install bison and flex; using yacc
and lex may require tweaking of the makefiles. You also need
Xpm (see comments in the Notes section below).
- You now have the option of using the configure-based system,
or the simple makefile system. Configure is more hard to debug
if things go wrong, but may be easier to use if they go OK :-)
Makefiles are easier to tweak.
COMPILING USING CONFIGURE
=========================
- You can use the wxGTK configure system to make wxMotif, or
you can follow the following steps to use the simpler (but
less automatic) makefile system. If using configure, the
following script should make the library and samples, when
run from the top-level wxWindows directory (see also 'makewxmotif'
in this directory). Make this script executable with the command
chmod a+x makewxmotif.
-------:x-----Cut here-----:x-----
# makewxmotif
# Sets permissions (in case we extracted wxMotif from zip files)
# and makes wxMotif.
# Call from top-level wxWindows directory.
# Note that this uses standard (but commonly-used) configure options;
# if you're feeling brave, you may wish to compile with threads.
# -- Julian Smart
chmod a+x configure config.sub config.guess setup/general/* setup/shared/*
./configure --with-shared --with-motif --without-gtk --with-debug_flag --with-debug_info --without-threads
make makefiles
make
-------:x-----Cut here-----:x-----
This script will build wxMotif using shared libraries.
- Change directory to a sample e.g. samples/minimal, and type make.
The binary will end up under the Linux (or other appropriate) subdirectory.
- To build an application outside the wxWindows hierarchy, you can
use `wx-config --cflags` when compiling source files and `wx-config --libs`
when linking, where wx-config is in the wxWindows root directory.
These invocations return the appropriate flags for the compiler.
- When compiling certain utilities such as Dialog Editor, you may find
that the makefile refers to wx-config as above. Unless you have used
"make install" to install wxWindows, wx-config won't be found, so
either edit the makefile to hard-wire the flags, or place wx-config
where it will be found by the makefile.
COMPILING USING MAKEFILES
=========================
- Choose a .env file from src/makeenvs that matches your
environment, and copy it to src/make.env. These are the
settings read by wxWindows for Motif makefiles.
- Edit src/make.env to change options according to your local
environment. In particular, change WXDIR to where wxWindows is
found on your system, or set the WXWIN environment variable
before compilation, e.g.:
export WXWIN=/home/jacs/wx2
Please feel free to contribute settings files for your environment.
- Change directory to src/motif and type:
make -f makefile.unx motif
This should make the library libwx_motif.a in the lib
directory. Note that this makefile system does not build shared
libraries, only static ones (that is, the wxWindows library will be
linked statically; to see remaining dependencies on shared libraries,
type e.g. ldd minimal_motif).
- Make a sample, such as the minimal sample:
cd samples/minimal
make -f makefile.unx motif
and run the resulting minimal_motif binary.
Troubleshooting
---------------
- If you have trouble compiling the file y_tab.c, or have strange
linking errors, check whether you're using a C or C++ compiler for this file.
You should specify a C compiler in the CCLEX variable in src/make.env.
You could also try using bison and flex instead of yacc and
lex.
- Solaris compilation with gcc: if the compiler has problems with the variable argument
functions, try putting the gcc fixinclude file paths early in the
include path.
- If you operator-related compile errors or strange memory problems
(for example in deletion of string arrays), set wxUSE_GLOBAL_MEMORY_OPERATORS
and wxUSE_MEMORY_TRACING to 0 in setup.h, and recompile.
- If you get an internal compiler error in gcc, turn off
optimisations.
- Problems with XtDestroyWidget crashing in ~wxWindow have been
reported on SGI IRIX 6.4. This has not yet been resolved, so
any advice here would be very welcome. See bugs.txt for a
possible temporary workaround (comment out the final
XtDestroyWidget from ~wxWindow in window.cpp).
- If you use flex and bison instead of yacc and lex, you may need
to change the relevant part of src/motif/makefile.unx to read:
../common/y_tab.c: ../common/parser.y
$(YACC) ../common/parser.y
mv ../common/parser.tab.c ../common/y_tab.c
(the 'mv' command needs to be changed)
- Some compilers, such as Sun C++, may give a lot of warnings about
virtual functions being hidden. Please ignore these, it's correct C++ syntax.
If you find any incorrect instances, though, such as a
missing 'const' in an overridden function, please let us know.
Other Notes
-----------
- Better installation and makefile systems are
required. A revised configure system is in preparation.
- Debugging mode is switched on by default. To compile in non-debug
mode, remove the -D__WXDEBUG__ switch in make.env (or if using the
configure system, change --with-debug_flag to --without_debug_flag
and --with-debug_info to --without-debug_info in the makewxmotif
script).
- Some classes can be switched off in include/wx/motif/setup.h,
if you are having trouble with a particular file. However,
I'd prefer you to fix the problem and send the fix to me :-) or at
least let me know about it.
- Thread support is switched off by default in setup.h (wxUSE_THREADS)
because standard Unices often do not have the necessary thread library
installed. Please see ../docs/gtk/install.txt for more details on this.
For Linux, the problem is expected to go away with future
distributions of the operating system.
- If you run into problems with a missing X11/Xpm.h header, you
need to install the XPM package. It can be obtained from:
ftp://ftp.x.org/contrib/libraries/xpm-3.4k.tar.gz
http://sunfreeware.com
You may need to modify make.env to add -I and -L options pointing to where Xpm
is installed and possibly change bitmap.cpp to
include <xpm.h> instead of <X11/xpm.h>
Alternatively, edit include/motif/setup.h, set wxUSE_XPM
to 0, and recompile. You will not be able to load any XPMs,
though (currently the only supported colour bitmap format).
Bug reports
-----------
Please send bug reports with a description of your environment,
compiler and the error message(s) to the wxwin-users mailing list at:
