Yes, that is how I build the win32 installers.  Look at the
instructions in setupext.py for win32 -- they point you to a tarfile
win32_static.tar.gz of dependencies (zlib, png and freetype) that you
will need to untar in your build dir.  You can skip the GTK stuff in
the build instructions if you do not want to use GTK on win32; in this
case you will probably want to change the default backend in
matplotlibrc to something else *before* you build.  Also, note that
matplotlib uses a conditional compilation depending on what modules it
finds at compile time.  So if you want to build for Numeric and
numarray, make sure you have installed both before compiling
matplotlib.  If you want to compile the gtk* backends, make sure you
have installed pygtk and the gtk runtime and dev libs.  And so on.

Hello,

I saw John Hunter's post a moment ago on building a win installer for
the basemap module. Is is possible to build the matplotlib package
itself with mingw/msys?

Regards,
ST

I will try and get this done on Monday.  

Note that setting up a free win32 build environment using mingw is
not very difficult. Here are my notes for setting it up -- replace any
version numbers with the most recent

== Required setup ==

  * Download MinGW-3.1.0-1.exe and MSYS-1.0.10.exe from
    http://sourceforge.net/project/showfiles.php?group_id=2435&package_id=82721
    and install both in C:\MinGW

  * Download pexports-0.42h 
    from http://starship.python.net/crew/kernr/mingw32/pexports-0.42h.zip 
    and extract it to C:\Program Files\pexports-0.42h

For compiling C++ extensions under mingw, I found I needed to patch
c:/Python23/Lib/distutils/cygwinccompiler.py to work with g++.  Find
the set_executables part and change it to

        self.set_executables(compiler='gcc -mcygwin -O -Wall',
                             compiler_cxx='g++ -mcygwin -O -Wall',
                             compiler_so='gcc -mcygwin -mdll -O -Wall',
                             linker_exe='gcc -mcygwin',
                             linker_so=('%s -mcygwin %s' %
                                        (self.linker_dll, shared_option)))


The compiler_cxx is where the change is.

For Python2.4 there is another oneline change you must make; see
http://mail.python.org/pipermail/python-list/2004-December/254826.html.
You must comment out

               #self.dll_libraries = ['msvcr71']


== THE BUILD ==

Execute the following profile batch file to setup path and
environment variables

  SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;c:\Python23;c:\mingw\bin;c:\mingw\mingw32\bin;c:\msys\1.0\bin
  set LDD=gcc
  set CC=gcc
  set CXX=g++
  set CFLAGS=-mms-bitfields


Execute the command below, changing the version numbers for other
pythons


  copy c:\windows\system32\python24.dll .
  c:\progra~1\pexports-0.42h\bin\pexports python24.dll > python24.def
  c:\MinGW\bin\dlltool --dllname python24.dll --def python24.def --output-lib libpython24.a

  copy libpython24.a c:\python24\libs
  del python24.dll
  del libpython24.a


Build the python binary installer for the package of your choice

  python setup.py build --compiler=mingw32 bdist_wininst --install-script postinstall.py
