building matplotlib with homebrew python and XQuartz 2.7.5

Development matplotlib-devel
1

I’m trying to get matplotlib working with the following setup on OSX 10.9.3

rail:~ brew$ gcc --version

gcc (GCC) 4.8.2

rail:~ brew$ python --version

Python 2.7.6

pip install git+git://github.com/matplotlib/matplotlib.git (as of today at 11am PDT)

Problem 1: couldn’t find a freetype header – googling supplied the fix:

sudo ln -s /usr/X11/include/freetype2/freetype /usr/X11/include/.

per http://stackoverflow.com/questions/19697457/numpy-matplotlib-install-error-ftheader-h-no-such-file-or-directory

Problem 2: I’m getting a fatal syntax error in _macosx.m:

/usr/local/bin/gcc -fno-strict-aliasing -fno-common -dynamic -I/usr/local/include -I/usr/local/opt/sqlite/include -DNDEBUG -g -fwrapv -O3 -Wall -DPY_ARRAY_UNIQUE_SYMBOL=MPL_matplotlib_backends__macosx_ARRAY_API -DPYCXX_ISO_CPP_LIB=1 -I/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/numpy/core/include -I/usr/local/include -I/usr/include -I/usr/X11/include -I. -Iextern/agg24/include -Iextern -I/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c src/_macosx.m -o build/temp.macosx-10.8-x86_64-2.7/src/_macosx.o

thanks in advance for suggestions on how to proceed – Phil

Any reason you’re trying to compile with gcc? I think most of the homebrew build recipes are tested using clang.

Thanks, that worked. (I had CC=gcc to keep things compatible with linux).

For anyone coming to this thread with the same error, note that you also need to do

export CC=/usr/bin/clang

export FC-=/usr/local/bin/fortran

to get

pip install scipy

to work.
