Using igraph with py2app on Mac OS X
Bernie Hogan wrote on the igraph mailing list:
There is something strange in the py2app installer that doesn't properly include the core.so file from igraph, and change the path appropriately. So in my case I had to do the following
sudo mkdir /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/igraph/
cp /Library/Python/2.5/site-packages/igraph/core.so /System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/lib-dynload/igraph/
This puts the core.so file in this particular location. The program finds it in this location and everything works.
Thanks Bernie for sharing this!
