wxWindows 2.0 for Motif installation
------------------------------------
-- Prerequisites: Motif 1.2 or above, or
- Lesstif (not yet tested).
+IMPORTANT NOTE: If you experience problems installing, please re-read this
+ instructions and other related files (todo.txt, bugs.txt and
+ osname.txt for your platform if it exists) 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
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
+ libXpm (see comments in the Notes section below) if you want to have
+ XPM support in wxWindows (recommended).
+
+- You now have the option of using the configure-based system, or the simple
+ makefile system.
+
+ Using configure is the recommended way to build the library. If it doesn't
+ work for you for whatever reason, please report it (together with detailed
+ information about your platform and the (relevant part of) contents of
+ config.log file) to wxwin-developers@wx.dent.med.uni-muenchen.de.
+
+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:
+ # if they're not supported by the target platform, they will be disabled
+ # anyhow
+ # -- 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
+ -------: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, or add the directory where you have
+ installed wxWindows to your PATH.
+
+- If switching between wxMotif and wxGTK, you should remove the
+ config.cache file manually before running configure again.
+
+COMPILING USING MAKEFILES
+=========================
+
+- Copy the file include/wx/motif/setup0.h to include/wx/motif/setup.h and
+ edit it if you wish to enable/disable some library features
+
+- 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
export WXWIN=/home/jacs/wx2
- Later, there will be a better makefile system
- and/or alternate make.env files as per wxWindows 1.68.
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.
+ 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:
and run the resulting minimal_motif binary.
-Notes:
-------
+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. I didn't use the wxGTK system because I couldn't
- understand it or make it work with wxMotif. Also I think
- we should use something that can be made to work easily
- with applications outside the wxWindows hierarchy.
+ 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.
+- Debugging mode is switched on by default in the makefiles, but using
+ configure will create a release build of the library by default: it's
+ recommended to use --with-debug_info and --with-debug_flag configure
+ switches while developing your application. 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.
+ The systems for which thread support is known to work are Linux with libc6
+ (a.k.a. glibc2), Solaris 2.5 and 2.6 (provided that X libraries are thread
+ safe) and, to some extent, FreeBSD 2.8 and 3.1 (any feedback on thread
+ support under FreeBSD as well as the systems not mentioned here would be
+ appreciated).
+
- 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
+ Alternatively, edit include/wx/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).
