Finally get cairo to work with igraph

I have an anaconda distribution of python, so I tried

conda install cairo

conda install pycairo

But the latter throws error cannot find pixman even after I conda install pixman succesfully. So I gave up on this route and

brew install cairo

brew install py2cairo

This way cairo is installed in the brew directory. To use it with anaconda python, add it to the sys path

import sys

sys.path.append(“/usr/local/lib/python2.7/site-packages”)

Then it works!

p.s. to manually compile pycairo, remember to add cairo to the path because I had hard time to have configure find cairo. This is not necessary if you use brew.

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig

pkg-config –cflags-only-I cairo
