+You'll need OS/2 Warp (4.00FP#6), X-Free86/2 (3.3.3 or newer),
+Lesstif (0.89.1 or newer), emx (0.9d fix 1), flex (2.5.4),
+yacc (1.8), unix like shell, e.g. korn shell (5.2.13),
+Autoconf (2.13), GNU file utilities (3.6),
+GNU text utilities (1.3), GNU shell utilites (1.12), m4 (1.4),
+sed (2.05), grep (2.0), Awk (3.0.3), GNU Make (3.76.1).
+
+Open an OS/2 prompt and switch to the directory above.
+First set some global environment variables we need:
+
+SET CXXFLAGS=-Zmtd -D__ST_MT_ERRNO__
+SET CFLAGS=-Zmtd -D__ST_MT_ERRNO__
+SET OSTYPE=OS2X
+SET COMSPEC=sh
+
+Notice you can choose whatever you want, if you don't like OS2X.
+
+Now, run autoconf in the main directory and in the samples, demos
+and utils subdirectory. This will generate the OS/2 specific
+versions of the configure scripts. Now run
+ configure --with-motif
+as described above.
+
+To verify Lesstif installation, configure will try to compile a
+sample program that requires X headers/libraries to be either
+available via C_INCLUDE_PATH and LIBRARY_PATH or you need to
+explicitly set CFLAGS prior to running configure.
+
+If you have pthreads library installed, it will be autodetected
+and the library will be compiled with thread-support.
+
+Note that configure assumes your flex will generate files named
+"lexyy.c", not "lex.yy.c". If you have a version which does
+generate "lex.yy.c", you need to manually change the generated
+makefile.
+
+* 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. 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
+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.
