[Libvir] Re: libvirt for Python on Windows
Aha, the big question.
So far I only have loose notes, but basically it comes down to the
instructions below.
I used SWIG (http://www.swig.org/) to build the DLL of the Python module.
My setup had Python 2.4 installed in C:\Prog\Python24. Of course the
required C dependancies where also already met on my system (including
libxen).
I have quite some experience in porting *nix stuff to Windows/win32
using MinGW/MSYS, but Python was new to me.
Nevertheless it took my days (well, nights mostly) to get this result,
but the instructions below aren't too long. So I believe it shouldn't
require that many changes to sources and autoconf/automake stuff to
incorporate the MinGW/MSYS port.
I'm afraid there is still some work ahead meeting all the Python
dependancies. If we're lucky they will exist for Windows. Otherwise they
will need porting too (hopefully easier than libvirt).
Here goes:
