He matado medio día tratando de compilar matplotlib para python en Snow Leopard. He usado los artículos de Google y encontré esta útil página (http://blog.hyperjeff.net/?p=160) pero aún no puedo hacer que compile. Veo comentarios de otros usuarios en esa página, así que sé que no estoy solo.Compilar Matplotlib para Python en Snow Leopard
Ya instalé zlib, libpng y freetype de forma independiente.
edité el archivo make.osx para contener esta en la parte superior:
PREFIX=/usr/local
PYVERSION=2.6
PYTHON=python${PYVERSION}
ZLIBVERSION=1.2.3
PNGVERSION=1.2.33
FREETYPEVERSION=2.3.5
MACOSX_DEPLOYMENT_TARGET=10.6
## You shouldn't need to configure past this point
PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"
CFLAGS="-Os -arch x86_64 -arch i386 -I${PREFIX}/include"
LDFLAGS="-arch x86_64 -arch i386 -L${PREFIX}/lib"
CFLAGS_DEPS="-arch i386 -arch x86_64 -I${PREFIX}/include -I${PREFIX}/include/freetype2 -isysroot /Developer/SDKs/MacOSX10.6.sdk"
LDFLAGS_DEPS="-arch i386 -arch x86_64 -L${PREFIX}/lib -syslibroot,/Developer/SDKs/MacOSX10.6.sdk"
Luego ejecutar:
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig" &&\
export MACOSX_DEPLOYMENT_TARGET=10.6 &&\
export CFLAGS="-Os -arch x86_64 -arch i386 -I/usr/local/include" &&\
export LDFLAGS="-arch x86_64 -arch i386 -L/usr/local/lib" &&\
python2.6 setup.py build

estoy:
sudo make -f make.osx mpl_build
que me da acaba de perder.
'make.osx' descargará automáticamente freetype/libpng/zlib. –
