[igraph] Installing python-igraph on MAC OS X (tiger)

[Alessandro Antonucci]

Hello everyone,

I am trying to install python-igraph on my  dual-core mac book.
I'm still running Tiger and the Leopard installer doesn't work. 
So, I'm trying to compile the sources.

The compilation of igraph seems ok, and 
the 107 tests of the corresponding testsuite 
were successful.

The problem arises when I want to install 
python-igraph. If I type:

>python2.5 setup.py install

the output is the following:

Include path: /usr/local/include/igraph
Library path: /usr/local/lib
running install

lipo: can't open input file: /var/tmp//ccDWw90E.out (No such file or directory)
error: command 'gcc' failed with exit status 1

Someone can tell me how should I modify the setup file
in order to fix this problem?

The only igraph directory in my system is

/Library/Python/2.5/site-package/igraph/

and I've added this path to the LIBIGRAPH_FALLBACK_INCLUDE_DIRS 
of the setup.py file, but nothing changes.

Best regards,

Alessandro
