wxWindows 2.0 for Motif installation
------------------------------------

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

- Download the files wx200gen.zip and wx200mot.zip, and
  documentation in a preferred format, such as wx200htm.zip
  or wx200pdf.zip.

- 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
  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
  Xpm (see comments in the Notes section below).

- You now have the option of using the configure-based system,
  or the simple makefile system. Configure is more hard to debug
  if things go wrong, but may be easier to use if they go OK :-)
  Makefiles are easier to tweak.

COMPILING USING CONFIGURE
=========================

- 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 'makewxmotif'
  in this directory). 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.
  # -- Julian Smart
  chmod a+x configure config.sub config.guess setup/general/* setup/shared/*
  ./configure --with-shared --with-motif --without-gtk --with-debug_flag --with-debug_info --without-threads
  make makefiles
  make
  -------:x-----Cut here-----:x-----

  This script will build wxMotif using shared libraries.

- Change directory to a sample e.g. samples/minimal, and type make.
  The binary will end up under the Linux (or other appropriate) subdirectory.

- To build an application outside the wxWindows hierarchy, you can
  use `wx-config --cflags` when compiling source files and `wx-config --libs`
  when linking, where wx-config is in the wxWindows root directory.
  These invocations return the appropriate flags for the compiler.

- When compiling certain utilities such as Dialog Editor, you may find
  that the makefile refers to wx-config as above. Unless you have used
  "make install" to install wxWindows, wx-config won't be found, so
  either edit the makefile to hard-wire the flags, or place wx-config
  where it will be found by the makefile.

COMPILING USING MAKEFILES
=========================

- 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
  before compilation, e.g.:

    export WXWIN=/home/jacs/wx2

  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. 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:

    cd samples/minimal
    make -f makefile.unx motif

  and run the resulting minimal_motif binary.

Notes:
------

- Better installation and makefile systems are
  required. A revised configure system is in preparation.

- Debugging mode is switched on by default. 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.
  For Linux, the problem is expected to go away with future
  distributions of the operating system.

- 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.

- 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
  to 0, and recompile. You will not be able to load any XPMs,
  though (currently the only supported colour bitmap format).

- Please send bug reports with a description of your environment,
  compiler and the error message(s) to the wxwin-users mailing list at:

    wxwin-users@wx.dent.med.uni-muenchen.de
