   1 wxWindows 2.0 for Motif installation
   2 ------------------------------------
   3
   4 IMPORTANT NOTE: If you experience problems installing, please
   5 re-read this instructions and other related files (todo.txt,
   6 bugs.txt etc.) carefully before mailing wxwin-users or
   7 the author. Preferably, try to fix the problem first and
   8 then send a patch to the author.
   9
  10 - Prerequisites: Motif 1.2 or above, or Lesstif
  11   (not yet tested). Motif 2.0 and above may also be suitable.
  12
  13 - Download the files wx200gen.zip and wx200mot.zip, and
  14   documentation in a preferred format, such as wx200htm.zip
  15   or wx200pdf.zip.
  16
  17 - Make a directory such as ~/wx and unzip the files into this
  18   directory. Use the -a option if available to convert the ASCII
  19   files to Unix format. Don't worry about files being
  20   overwritten: they should be identical anyway.
  21
  22   (See http://www.cdrom.com/pub/infozip/ if you don't have zip/unzip
  23   already installed. Zip isn't the same as gzip!)
  24
  25 - It is recommended that you install bison and flex; using yacc
  26   and lex may require tweaking of the makefiles. You also need
  27   Xpm (see comments in the Notes section below).
  28
  29 - You now have the option of using the configure-based system,
  30   or the simple makefile system. Configure is more hard to debug
  31   if things go wrong, but may be easier to use if they go OK :-)
  32   Makefiles are easier to tweak.
  33
  34 COMPILING USING CONFIGURE
  35 =========================
  36
  37 - You can use the wxGTK configure system to make wxMotif, or
  38   you can follow the following steps to use the simpler (but
  39   less automatic) makefile system. If using configure, the
  40   following script should make the library and samples, when
  41   run from the top-level wxWindows directory (see also 'makewxmotif'
  42   in this directory). Make this script executable with the command
  43   chmod a+x makewxmotif.
  44
  45   -------:x-----Cut here-----:x-----
  46   # makewxmotif
  47   # Sets permissions (in case we extracted wxMotif from zip files)
  48   # and makes wxMotif.
  49   # Call from top-level wxWindows directory.
  50   # Note that this uses standard (but commonly-used) configure options;
  51   # if you're feeling brave, you may wish to compile with threads.
  52   # -- Julian Smart
  53   chmod a+x configure config.sub config.guess setup/general/* setup/shared/*
  54   ./configure --with-shared --with-motif --without-gtk --with-debug_flag --with-debug_info --without-threads
  55   make makefiles
  56   make
  57   -------:x-----Cut here-----:x-----
  58
  59   This script will build wxMotif using shared libraries.
  60
  61 - Change directory to a sample e.g. samples/minimal, and type make.
  62   The binary will end up under the Linux (or other appropriate) subdirectory.
  63
  64 - To build an application outside the wxWindows hierarchy, you can
  65   use `wx-config --cflags` when compiling source files and `wx-config --libs`
  66   when linking, where wx-config is in the wxWindows root directory.
  67   These invocations return the appropriate flags for the compiler.
  68
  69 - When compiling certain utilities such as Dialog Editor, you may find
  70   that the makefile refers to wx-config as above. Unless you have used
  71   "make install" to install wxWindows, wx-config won't be found, so
  72   either edit the makefile to hard-wire the flags, or place wx-config
  73   where it will be found by the makefile.
  74
  75 - If switching between wxMotif and wxGTK, you should remove the
  76   config.cache file manually before running configure again.
  77
  78 COMPILING USING MAKEFILES
  79 =========================
  80
  81 - Choose a .env file from src/makeenvs that matches your
  82   environment, and copy it to src/make.env. These are the
  83   settings read by wxWindows for Motif makefiles.
  84
  85 - Edit src/make.env to change options according to your local
  86   environment. In particular, change WXDIR to where wxWindows is
  87   found on your system, or set the WXWIN environment variable
  88   before compilation, e.g.:
  89
  90     export WXWIN=/home/jacs/wx2
  91
  92   Please feel free to contribute settings files for your environment.
  93
  94 - Change directory to src/motif and type:
  95
  96     make -f makefile.unx motif
  97
  98   This should make the library libwx_motif.a in the lib
  99   directory. Note that this makefile system does not build shared
 100   libraries, only static ones (that is, the wxWindows library will be
 101   linked statically; to see remaining dependencies on shared libraries,
 102   type e.g. ldd minimal_motif).
 103
 104 - Make a sample, such as the minimal sample:
 105
 106     cd samples/minimal
 107     make -f makefile.unx motif
 108
 109   and run the resulting minimal_motif binary.
 110
 111 Troubleshooting
 112 ---------------
 113
 114 - If you have trouble compiling the file y_tab.c, or have strange
 115   linking errors, check whether you're using a C or C++ compiler for this file.
 116   You should specify a C compiler in the CCLEX variable in src/make.env.
 117   You could also try using bison and flex instead of yacc and
 118   lex.
 119
 120 - Solaris compilation with gcc: if the compiler has problems with the variable argument
 121   functions, try putting the gcc fixinclude file paths early in the
 122   include path.
 123
 124 - If you operator-related compile errors or strange memory problems
 125   (for example in deletion of string arrays), set wxUSE_GLOBAL_MEMORY_OPERATORS
 126   and wxUSE_MEMORY_TRACING to 0 in setup.h, and recompile.
 127
 128 - If you get an internal compiler error in gcc, turn off
 129   optimisations.
 130
 131 - Problems with XtDestroyWidget crashing in ~wxWindow have been
 132   reported on SGI IRIX 6.4. This has not yet been resolved, so
 133   any advice here would be very welcome. See bugs.txt for a
 134   possible temporary workaround (comment out the final
 135   XtDestroyWidget from ~wxWindow in window.cpp).
 136
 137 - If you use flex and bison instead of yacc and lex, you may need
 138   to change the relevant part of src/motif/makefile.unx to read:
 139
 140   ../common/y_tab.c: ../common/parser.y
 141      $(YACC) ../common/parser.y
 142      mv ../common/parser.tab.c ../common/y_tab.c
 143
 144   (the 'mv' command needs to be changed)
 145
 146 - Some compilers, such as Sun C++, may give a lot of warnings about
 147   virtual functions being hidden. Please ignore these, it's correct C++ syntax.
 148   If you find any incorrect instances, though, such as a
 149   missing 'const' in an overridden function, please let us know.
 150
 151 Other Notes
 152 -----------
 153
 154 - Better installation and makefile systems are
 155   required. A revised configure system is in preparation.
 156
 157 - Debugging mode is switched on by default. To compile in non-debug
 158   mode, remove the -D__WXDEBUG__ switch in make.env (or if using the
 159   configure system, change --with-debug_flag to --without_debug_flag
 160   and --with-debug_info to --without-debug_info in the makewxmotif
 161   script).
 162
 163 - Some classes can be switched off in include/wx/motif/setup.h,
 164   if you are having trouble with a particular file. However,
 165   I'd prefer you to fix the problem and send the fix to me :-) or at
 166   least let me know about it.
 167
 168 - Thread support is switched off by default in setup.h (wxUSE_THREADS)
 169   because standard Unices often do not have the necessary thread library
 170   installed. Please see ../docs/gtk/install.txt for more details on this.
 171   For Linux, the problem is expected to go away with future
 172   distributions of the operating system.
 173
 174 - If you run into problems with a missing X11/Xpm.h header, you
 175   need to install the XPM package. It can be obtained from:
 176
 177   ftp://ftp.x.org/contrib/libraries/xpm-3.4k.tar.gz
 178   http://sunfreeware.com
 179
 180   You may need to modify make.env to add -I and -L options pointing to where Xpm
 181   is installed and possibly change bitmap.cpp to
 182   include <xpm.h> instead of <X11/xpm.h>
 183
 184   Alternatively, edit include/motif/setup.h, set wxUSE_XPM
 185   to 0, and recompile. You will not be able to load any XPMs,
 186   though (currently the only supported colour bitmap format).
