Compile Matplotlib for Python on Snow Leopard

Question
I've killed half a day trying to compile matplotlib for python on Snow Leopard. I've used the googles and found this helpful page (http://blog.hyperjeff.net/?p=160) but I still can't get it to compile. I see comments from other users on that page, so I know I'm not alone.
I already installed zlib, libpng and freetype independently.
I edited the make.osx file to contain this at the top:
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"
I then run:
sudo make -f make.osx mpl_build
which gives me:
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" &&\

I'm just lost.
Solution
According to your error message you have missing freetype headers. Can you locate them using system search functionalities. I will not lecture on using a pre-built package since I love scratching my head and compiling from the start as well.
OTHER TIPS
This solution worked for me on OSX 10.8.3:
ln -s /usr/local/include/freetype2/freetype/ /usr/include/freetype
(Credit really goes to: http://simpleyuan.blogspot.com/2012/08/matplotlib-error-mac-os-x.html)
You can also build by using
$ python setup.py build
with the following patch applied to setupext.py

def getoutput(s):
For Python.org 2.7.1:
I used a mix of the instructions. It basically worked by using the libpng in OSX's /usr/X11
Downloaded, built and installed (make install) freetype2 v2.4.4 & zlib v1.2.5. Did not use make deps.
Modified setupext.py to have
module.include_dirs.extend(incdirs) module.include_dirs.append('.') module.include_dirs.append('/usr/local/include') module.include_dirs.append('/usr/local/include/freetype2') module.include_dirs.append('/usr/X11/include') module.library_dirs.extend(libdirs) module.library_dirs.append('/usr/local/lib') module.library_dirs.append('/usr/X11/lib')
Modified make.osx to include the same /usr/X11 info, png version 1.2.5 is OSX 10.6.6 current native
PYVERSION=2.7 PYTHON=python${PYVERSION} ZLIBVERSION=1.2.5 PNGVERSION=1.2.44 FREETYPEVERSION=2.4.4 MACOSX_DEPLOYMENT_TARGET=10.6 OSX_SDK_VER=10.6 ARCH_FLAGS="-arch i386-arch x86_64" PREFIX=/usr/local MACPREFIX=/usr/X11 PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig" CFLAGS="-arch i386 -arch x86_64 -I${PREFIX}/include -I${PREFIX}/include/freetype2 -I${MAXPREFIX}/include -isysroot /Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk" LDFLAGS="-arch i386 -arch x86_64 -L${PREFIX}/lib -L/usr/X11/lib -syslibroot,/Developer/SDKs/MacOSX${OSX_SDK_VER}.sdk" FFLAGS="-arch i386 -arch x86_64"
Then the standard
sudo make -f make.osx mpl_build sudo make -f make.osx mpl_install sudo python setup.py install
Crikey... seems to work. Now have Image & MDP & pylab & matplotlib with 2.7.1 on 10.6.6
Image module (Imaging-1.7.7) works okay as long as you install libjpeg. I used jpegsrc.v8c
and it seemed happy enough.
I just got it to compile. I added freetype2 in the include path for the CFLAGS in the make.osx file. Now the top of make.osx is:
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${PREFIX}/include -I${PREFIX}/include/freetype2"
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"
Then I ran these commands, and it compiled and installed perfectly.
sudo make -f make.osx mpl_build
sudo make -f make.osx mpl_install
as suggested elsewhere, macports works fine on multiple architecture and versions of MacOsX + allows updates and more:
$ port search matplot
py-matplotlib @0.99.0 (python, graphics, math)
matlab-like syntax for creating plots in python
py-matplotlib-basemap @0.99.4 (python, graphics, math)
matplotlib toolkit for plotting data on map projections
py25-matplotlib @0.99.0 (python, graphics, math)
matlab-like syntax for creating plots in python
py25-matplotlib-basemap @0.99.4 (python, graphics, math)
matplotlib toolkit for plotting data on map projections
py26-matplotlib @0.99.0 (python, graphics, math)
matlab-like syntax for creating plots in python
py26-matplotlib-basemap @0.99.4 (python, graphics, math)
matplotlib toolkit for plotting data on map projections
Found 6 ports.
$
in your case, simply issue :
$ sudo port install py26-matplotlib
it features the macosx backend (native cocoa) as default
You should really ask this on the matplotlib-users mailing list. It's monitored by actual matplotlib developers, which StackOverflow (AFAIK) isn't.
