Hi,
This patch reminded me to ask why the builtin libpng, zlib and
libfreetype on Mac OS 10.5 and later are not used to build Matplotlib,
removing the need to download these extra libraries. I was pleased to
discover that Snow Leopard shipped with libpng and libfreetype as part
of X11, only to find that even my old Leopard installation had them.
I've been successfully building Matplotlib against them on both
platforms. Besides skipping the download step, these libraries have
the advantage of being correct universal binaries, eliminating another
potential stumbling block. The only problem would be if these
libraries were outdated, but I haven't come across any problems yet.
For the record, I set the following environment variables in
~/.profile on Snow Leopard:
# These compiler flags ensure 32-bit + 64-bit code generation, as
Snow Leopard produces 64-bit code by default
export MACOSX_DEPLOYMENT_TARGET=10.6
export CFLAGS="-arch i386 -arch x86_64 -isysroot
/Developer/SDKs/MacOSX10.6.sdk"
export LDFLAGS="-arch i386 -arch x86_64
-syslibroot,/Developer/SDKs/MacOSX10.6.sdk"
export FFLAGS="-m32 -m64"
I then build a Matplotlib egg with:
CFLAGS=${CFLAGS}" -I/usr/X11/include -I/usr/X11/include/freetype2"
LDFLAGS=${LDFLAGS}" -L/usr/X11/lib" python setupegg.py bdist_egg
I've been meaning to publish my installation instructions for
numpy/scipy/matplotlib/ipython on Snow Leopard somewhere for quite a
while, but that will have to wait for another day... I've tried to
trim down my installation procedure to the minimum steps that will
guarantee a working system without introducing extra libraries /
Pythons / etc, so there might be some interest in it.
