wxWindows 2.0 for Motif installation
------------------------------------
-- Prerequisites: Motif 1.2 or above, or
- Lesstif (not yet tested).
+IMPORTANT NOTE:
-- Download the files wx200gen.zip and wx200mot.zip, and
- documentation in a preferred format, such as wx200htm.zip
- or wx200pdf.zip.
+ If you experience problems installing, please re-read these
+ 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.
+
+ When sending bug reports tell us what version of wxWindows you are
+ using (including the beta) and what compiler on what system. One
+ example: wxMotif 2.1 beta 6, egcs 1.1.1, Redhat 5.0
-- 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
+First steps
+-----------
+
+- Prerequisites: Motif 1.2 or above, or Lesstif
+ (not yet tested). Motif 2.0 and above may also be suitable.
+
+- Download the appropriate .tgz archive, or alternatively the files
+ wx200gen.zip and wx200mot.zip. Download documentation in a preferred format,
+ such as wx200htm.zip or wx200pdf.zip.
+
+- Make a directory such as ~/wx and unarchive the files into this
+ directory. If using the zip archives, 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
+ 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
+=========================
+
+* The most simple case
+-----------------------
+
+If you compile wxWindows on Linux for the first time and don't like to read
+install instructions just do (in the base dir):
+
+> ./configure --with-motif
+> make
+> su <type root password>
+> make install
+> ldconfig
+> exit
+
+Afterwards you can continue with
+
+> make
+> su <type root password>
+> make install
+> ldconfig
+> exit
+
+If you want to remove wxWindows on Unix you can do this:
+
+> su <type root password>
+> make uninstall
+> ldconfig
+> exit
+
+* The expert case
+-----------------
+
+If you want to do some more serious cross-platform programming with wxWindows,
+such as for GTK and Motif, you can now build two complete libraries and use
+them concurretly. For this end, you have to create a directory for each build
+of wxWindows - you may also want to create different versions of wxWindows
+and test them concurrently. Most typically, this would be a version configured
+with --enable-debug_flag and one without. Note, that only one build can currently
+be installed, so you'd have to use local version of the library for that purpose.
+For building three versions (one GTK, one Motif and a debug version of the GTK
+source) you'd do this:
+
+md buildmotif
+cd buildmotif
+../configure --with-motif
+make
+cd ..
+
+md buildgtk
+cd buildgtk
+../configure --with-gtk
+make
+cd ..
+
+md buildgtkd
+cd buildgtkd
+../configure --with-gtk --enable-debug_flag
+make
+cd ..
+
+* The most simple errors
+------------------------
+
+You get errors during compilation: The reason is that you probably have a broken
+compiler, which includes almost everything that is called gcc. If you use gcc 2.8
+you have to disable optimsation as the compiler will give up with an internal
+compiler error.
+
+If there is just any way for you to use egcs, use egcs. We cannot fix gcc.
+
+You get immediate segfault when starting any sample or application: This is either
+due to having compiled the library with different flags or options than your program -
+typically you might have the __WXDEBUG__ option set for the library but not for your
+program - or due to using a broken compiler (and its optimisation) such as GCC 2.8.
+
+* The most simple program
+-------------------------
+
+Now create your super-application myfoo.app and compile anywhere with
+
+g++ myfoo.cpp `wx-config --libs --cflags` -o myfoo
+
+* General
+-----------------------
+
+The Unix variants of wxWindows use GNU configure. If you have problems with your
+make use GNU make instead.
+
+If you have general problems with installation, read my homepage at
+
+ http://wesley.informatik.uni-freiburg.de/~wxxt
+
+for newest information. If you still don't have any success, please send a bug
+report to one of our mailing lists (see my homepage) INCLUDING A DESCRIPTION OF
+YOUR SYSTEM AND YOUR PROBLEM, SUCH AS YOUR VERSION OF GTK, WXGTK, WHAT DISTRIBUTION
+YOU USE AND WHAT ERROR WAS REPORTED. I know this has no effect, but I tried...
+
+* GUI libraries
+-----------------------
+
+wxWindows/Motif requires the Motif library to be installed on your system. As
+an alternative, you may also use the free library "lesstif" which implements
+most of the Motif API without the licence restrictions of Motif.
+
+You can get the newest version of the Lesstif from the lesstif homepage at:
+
+ http://www.lesstif.org
+
+* Additional libraries
+-----------------------
+
+wxWindows/Motif requires a thread library and X libraries known to work with threads.
+This is the case on all commercial Unix-Variants and all Linux-Versions that are
+based on glibc 2 except RedHat 5.0 which is broken in many aspects. As of writing
+this, these Linux distributions have correct glibc 2 support:
+
+ - RedHat 5.1
+ - Debian 2.0
+ - Stampede
+ - DLD 6.0
+ - SuSE 6.0
+
+You can disable thread support by running
+
+./configure "--disable-threads"
+make
+su <type root password>
+make install
+ldconfig
+exit
+
+NB: DO NOT COMPILE WXGTK WITH GCC AND THREADS, SINCE ALL PROGRAMS WILL
+CRASH UPON START-UP! Just always use egcs and be happy.
+
+* Building wxMotif on SGI
+--------------------------
+
+Using the SGI native compilers, it is recommended that you
+also set CFLAGS and CXXFLAGS before running configure. These
+should be set to :
+
+CFLAGS="-mips3 -n32"
+CXXFLAGS="-mips3 -n32"
+
+This is essential if you want to use the resultant binaries
+on any other machine than the one it was compiled on. If you
+have a 64bit machine (Octane) you should also do this to ensure
+you don't accidently build the libraries as 64bit (which is
+untested).
+
+The SGI native compiler support has only been tested on Irix 6.5.
+
+* Create your configuration
+-----------------------------
+
+Usage:
+ ./configure options
+
+If you want to use system's C and C++ compiler,
+set environment variables CC and CCC as
+
+ % setenv CC cc
+ % setenv CCC CC
+ % ./configure options
+
+to see all the options please use:
+
+ ./configure --help
+
+The basic philosophy is that if you want to use different
+configurations, like a debug and a release version,
+or use the same source tree on different systems,
+you have only to change the environment variable OSTYPE.
+(Sadly this variable is not set by default on some systems
+in some shells - on SGI's for example). So you will have to
+set it there. This variable HAS to be set before starting
+configure, so that it knows which system it tries to
+configure for.
+
+Configure will complain if the system variable OSTYPE has
+not been defined. And Make in some circumstances as well...
+
+
+* General options
+-------------------
+
+Given below are the commands to change the default behaviour,
+i.e. if it says "--disable-threads" it means that threads
+are enabled by default.
+
+Many of the confiugre options have been thoroughly tested
+in wxWindows snapshot 6, but not yet all (ODBC not).
+
+You have to add --with-motif on platforms, where Motif is
+not the default (on Linux, configure will deafult to GTK).
+
+ --without-gtk Don't use the GIMP ToolKit (GTK)
+
+ --with-motif Use either Motif or Lesstif
+ Configure will look for both.
+
+The following options handle the kind of library you want to build.
+
+ --disable-threads Compile without thread support. Threads
+ support is also required for the
+ socket code to work.
+
+ --disable-shared Do not create shared libraries.
+
+ --disable-optimise Do not optimise the code. Can
+ sometimes be useful for debugging
+ and is required on some architectures
+ such as Sun with gcc 2.8.X which
+ would otherwise produce segvs.
+
+ --enable-profile Add profiling info to the object
+ files. Currently broken, I think.
+
+ --enable-no_rtti Enable compilation without creation of
+ C++ RTTI information in object files.
+ This will speed-up compilation and reduce
+ binary size.
+
+ --enable-no_exceptions Enable compilation without creation of
+ C++ exception information in object files.
+ This will speed-up compilation and reduce
+ binary size. Also fewer crashes during the
+ actual compilation...
+
+ --enable-no_deps Enable compilation without creation of
+ dependency information.
+
+ --enable-permissive Enable compilation without creation of
+ giving erros as soon as you compile with
+ Solaris ANSI-defying headers...
+
+ --enable-mem_tracing Add built-in memory tracing.
+
+ --enable-dmalloc Use the dmalloc memory debugger.
+ Read more at www.letters.com/dmalloc/
+
+ --enable-debug_info Add debug info to object files and
+ executables for use with debuggers
+ such as gdb (or its many frontends).
+
+ --enable-debug_flag Define __DEBUG__ and __WXDEBUG__ when
+ compiling. This enable wxWindows' very
+ useful internal debugging tricks (such
+ as automatically reporting illegal calls)
+ to work. Note that program and library
+ must be compiled with the same debug
+ options.
+
+* Feature Options
+-------------------
+
+Many of the confiugre options have been thoroughly tested
+in wxWindows snapshot 6, but not yet all (ODBC not).
+
+When producing an executable that is linked statically with wxGTK
+you'll be surprised at its immense size. This can sometimes be
+drastically reduced by removing features from wxWindows that
+are not used in your program. The most relevant such features
+are
+
+ --without-libpng Disables PNG image format code.
+
+ --without-libjpeg Disables JPEG image format code.
+
+ --without-odbc Disables ODBC code.
+
+ --disable-resources Disables the use of *.wxr type
+ resources.
+
+ --disable-threads Disables threads. Will also
+ disable sockets.
+
+ --disable-sockets Disables sockets.
+
+ --disable-dnd Disables Drag'n'Drop.
+
+ --disable-clipboard Disables Clipboard.
+
+ --disable-serial Disables object instance serialiasation.
+
+ --disable-streams Disables the wxStream classes.
+
+ --disable-file Disables the wxFile class.
+
+ --disable-textfile Disables the wxTextFile class.
+
+ --disable-intl Disables the internationalisation.
+
+ --disable-validators Disables validators.
+
+ --disable-accel Disables accel.
+
+Apart from disabling certain features you can very often "strip"
+the program of its debugging information resulting in a significant
+reduction in size.
+
+* Compiling
+-------------
+
+The following must be done in the base directory (e.g. ~/wxGTK
+or ~/wxWin or whatever)
+
+Now the makefiles are created (by configure) and you can compile
+the library by typing:
+
+ make
+
+make yourself some coffee, as it will take some time. On an old
+386SX possibly two weeks. During compilation, you'll get a few
+warning messages depending in your compiler.
+
+If you want to be more selective, you can change into a specific
+directiry and type "make" there.
+
+Then you may install the library and it's header files under
+/usr/local/include/wx and /usr/local/lib respectively. You
+have to log in as root (i.e. run "su" and enter the root
+password) and type
+
+ make install
+
+You can remove any traces of wxWindows by typing
+
+ make uninstall
+
+If you want to save disk space by removing unnecessary
+object-files:
+
+ make clean
+
+in the various directories will do the work for you.
+
+* Creating a new Project
+--------------------------
+
+1) The first way uses the installed libraries and header files
+automatically using wx-config
+
+g++ myfoo.cpp `wx-config --libs` `wx-config --cflags` -o myfoo
+
+Using this way, a make file for the minimal sample would look
+like this
+
+CC = g++
+
+minimal: minimal.o
+ $(CC) -o minimal minimal.o `wx-config --libs`
+
+minimal.o: minimal.cpp mondrian.xpm
+ $(CC) `wx-config --cflags` -c minimal.cpp -o minimal.o
+
+clean:
+ rm -f *.o minimal
+
+This is certain to become the standard way unless we decide
+to sitch to tmake.
+
+2) The other way creates a project within the source code
+directories of wxWindows. For this endeavour, you'll need
+GNU autoconf version 2.14 and add an entry to your Makefile.in
+to the bottom of the configure.in script and run autoconf
+and configure before you can type make.
+
+* Further notes by Julian Smart
+---------------------------------
+
+- You may find the following script useful for compiling wxMotif,
+ especially if installing from zips (which don't preserve file
+ permissions). 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
+ ./configure --with-shared --with-motif --without-gtk --with-debug_flag --with-debug_info --enable-debug --without-threads --without-sockets --without-odbc
+ make
+ -------:x-----Cut here-----:x-----
+
+ This script will build wxMotif using shared libraries. If you want to build
+ a static wxWindows library, use --disable-shared.
+
+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:
-- 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.
+ ../common/y_tab.c: ../common/parser.y
+ $(YACC) ../common/parser.y
+ mv ../common/parser.tab.c ../common/y_tab.c
-- Debugging mode is switched on by default. To compile in non-debug
- mode, remove the -D__WXDEBUG__ switch in make.env.
+ (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
+-----------
+
+- 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).
