Re: [igraph] Problem installing python-igraph on Mac OS X Lion related to ARPACK

[Jonathan Donges]

Hi,

I removed all older versions of the igraph C libraries and made sure that the 
libs are installed in /usr/local/lib. The headers are installed in 
/usr/local/include. I made sure that these directories are referenced both in 
the setup.cfg and setup.py files as recommended:

sudo python setup.py install
Using default include and library paths for compilation
If the compilation fails, please edit the LIBIGRAPH_FALLBACK_*
variables in setup.py or include_dirs and library_dirs in 
setup.cfg to point to the correct directories and libraries
where the C core of igraph is installed
()
Include path: /usr/include /usr/local/include
Library path: /usr/lib /usr/local/lib

I still get the same errors as before when trying to install python-igraph on 
Lion:

…

Do you have an idea what I could do next?

Thanks,
Jonathan
