-wxWindows 2.0 for Motif installation
+wxWindows 2.3 for Motif installation

 ------------------------------------
 
 ------------------------------------
 

+IMPORTANT NOTE:
+
+  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 2.3.0, egcs 1.1.1, Redhat 5.0
+
+First steps
+-----------
+

 - Prerequisites: Motif 1.2 or above, or Lesstif
   (not yet tested). Motif 2.0 and above may also be suitable.

 COMPILING USING CONFIGURE
 
 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 wxGTK on OS/2
+--------------------------
+
+Please send comments and question about the OS/2 installation
+to Andrea Venturoli <a.ventu@flashnet.it> and patches to
+the wxWindows mailing list.
+
+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...
+

 
 

-- 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 'makewx'
-  in this directory):
-
-  # Make wxMotif using the configure system
-  chmod a+x install/unix/config.sub
-  install/unix/setup/general/* \
-    install/unix/config.guess install/unix/setup/shared/*
-  cd install/unix
-  autoconf && ./configure --with-shared --with-motif --with-debug_flag \
-   --with-debug_info --without-threads
-  cd ../..
-  make makefiles
+* 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.
+
+* 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

+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

+- Some compilers, such as Sun C++, may give a lot of warnings about

+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.

-- 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.
+- 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).
