Re: [igraph] Problem un Update to python 2.5

[Tamas Nepusz]

Hi Sergio,

When you recompiled the Python interface (I assume you did that, do  
you?), did you remove the old build/ directory? I usually see this  
error message (or something like that) when I forgot to do so.

The reason why I am asking is that Py_InitModule4 does not exist in  
Python2.5 on a 64-bit system; more precisely, it is just a C  
preprocessor alias to Py_InitModule4_64; however, it did exist in  
Python2.4 for both 32 and 64-bit systems. It looks like you are still  
loading the "old" core.so (compiled for 2.4) that somehow got into the  
Python 2.5 search path.
