Some helper functions for building the C extensions
You may need to use the "basedirlist" option in setup.cfg to point
to the location of your required libs, eg, png, z, freetype,
overriding the settings hard-coded in the "basedir" directory
below.
DARWIN
I have installed all of the backends on OSX.
Tk: If you want to install TkAgg, I recommend the "batteries included"
binary build of Tcl/Tk at
http://www.apple.com/downloads/macosx/unix_open_source/tcltkaqua.html
GTK: I installed GTK from src as described at
http://www.macgimp.org/index.php?topic=gtk. There are several
packages, but all configure/make/make install w/o problem. In
addition to the packages listed there, You will also need libpng,
libjpeg, and libtiff if you want output to these formats from GTK.
WIN32 - MINGW
If you are sufficiently masochistic that you want to build this
yourself, download the win32_static dir from
http://matplotlib.sourceforge.net/win32_static.tar.gz and
see the README file in that dir
> python setup.py build --compiler=mingw32 bdist_wininst > build23.out
NOTE, if you are building on python24 on win32, see
http://mail.python.org/pipermail/python-list/2004-December/254826.html
WIN32 - VISUAL STUDIO 7.1 (2003)
This build is similar to the mingw. Download the visual studio static
dependencies from
http://matplotlib.sourceforge.net/win32_static_vs.tar.gz and
see the README in that dir
> python setup.py build --compiler=msvc bdist_wininst
