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" &&\
    python2.6 setup.py build

... snip ...

I'm just lost.

make.osx will automatically download freetype/libpng/zlib. — Sridhar Ratnakumar

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.

This solution worked for me on OSX 10.8.3:

ln -s /usr/local/include/freetype2/freetype/ /usr/include/freetype

For Homebrew: ln -s /usr/local/include/freetype2/ /usr/include/freetype

You can also build by using

$ python setup.py build

with the following patch applied to setupext.py

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.
