Re: [igraph] Installing igraph with EPD (enthought python distribution) on mac os x

[Tamás Nepusz]

Hi, 

I'm glad that it has been sorted out in the end. Anyway, since the installed 
igraph module worked fine in your base Python install, I was wondering whether 
you have accidentally executed "python setup.py install" using the base Python 
executable and not the one from EPD. Theoretically, setup.py queries the folder 
where the modules should be put from the Python executable, so the only way it 
could have ended up in your "base" Python install is that you executed it with 
/usr/bin/python and not EPD's python.

Note: easy_install python-igraph works only if igraph's header files are in 
/usr/include/igraph or /usr/local/include/igraph, or if pkg-config is installed 
and it "knows" where igraph's headers are. I have been considering to make 
igraph easy_installable in a way that it would download and configure the 
headers automatically if it cannot find the headers, but I have never had the 
time to do it properly.
