Re: [igraph] Installing igraph on ubuntu 14.04 64 bit

[Tamas Nepusz]

Hello,

If you are fine with igraph 0.6.5, why don’t you simply install the 
python-igraph package? (See: http://packages.ubuntu.com/trusty/python-igraph). 
If you need a newer version of python-igraph then your log seems weird because 
the installer from 0.7 should try to download and compile the C core of igraph 
if it finds that it isn’t installed yet (like in your case) instead of 
complaining about the absence of the C core.
