Re: [igraph] python 2.5 installer for igraph 5.2?

Hi Jose,

> Is there a python 2.5 installer for igraph 5.2 (latest)?
No, there isn't, at least not at the moment. The reason is that  
Windows XP that's running in my VirtualBox has Visual Studio 2008  
Express -- which is unsupported as a Python extension compiler before  
Python 2.6.

Well, it's not a trivial task but not impossible. We have a lot of  
experience in that now ;) The first thing is that you should try to  
stick to Microsoft Visual Studio because Python is also built with  
MSVC, hence it links to a different version of the Microsoft C Runtime  
than Cygwin or MinGW. If you try to compile igraph with MinGW or  
Cygwin, you will end up with mixing different versions of the C  
runtime and funny things will happen when a FILE* pointer is passed  
between the C core of igraph and Python (since the internal structure  
of a file object changed somewhere between the two runtimes). If you  
have an earlier Visual Studio (2003 or 2005) and you are willing to  
give it a go, I'm happy to send you the scripts that I use. Otherwise,  
I might try to set up another VM with an older MSVC and compile igraph  
with Python 2.5 there, but I can't promise anything.

Best,
