!!! When sending bug reports tell us what version of wxWindows you are using (including the beta) and what compiler on what system. One example: wxWINE 2.1 snapshot 6, egcs 1.1.1, Redhat 5.0 !!! * Preparing WINE ---------------- Most C++ compilers cannot compile the WINE sources yet (this includes all versions of g++ and ecgs) so you have to make a minimal change and recompile all of WINE in order to get anywhere. This change has do be applied to the /include/windef.h file, line 59 in the section "Calling convention defintions", where the sources reads: #if __i386__ which has to be changed into #if 0 After this change, you'll have to recompile all of WINE without forgetting to install it. The direct consequence of this change is that the Win32 binary emulator won't work anymore, as the change disables the Windows native calling convention. * The most simple case ----------------------- If you compile wxWindows on Unix for the first time and don't like to read install instructions just do (in the base dir): ./configure --with-wine make su make install ldconfig exit If you want to remove wxWindows on Unix you can do this: su 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 WINE and a debug version of the WINE source) you'd do this: md buildmotif cd buildmotif ../configure --with-motif make cd .. md buildwine cd buildwine ../configure --with-wine make cd .. md buildwined cd buildwined ../configure --with-wine --enable-debug_flag make cd .. * The most simple errors ------------------------ wxWINE doesn't work yet as WINE isn't really up to the task yet. 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 WINE, WXWINE, WHAT DISTRIBUTION YOU USE AND WHAT ERROR WAS REPORTED. I know this has no effect, but I tried... * GUI libraries ----------------------- wxWindows/WINE requires the WINE library to be installed on your system. You can get the newest version of the WINE from the WINE homepage at: http://www.winehq.com * 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 must do this by running configure with either of: --with-wine Use the WINE library The following options handle the kind of library you want to build. --enable-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-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. Not yet. } --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 the usual number of GNU tools, at least GNU automake version 1.4 GNU autoheader version 2.14 GNU autoconf version 2.14 GNU libtool version 1.3 and quite possibly GNU make GNU C++ and if you have all this then you probably know enough to go ahead yourself :-) ---------------------- In the hope that it will be useful, Robert Roebling
