[gtk-win32] Pygtk (hippocanvas) compilation

[Pietro Battiston <toobaz email it>]

Hello list,

I'm (it's been weeks since I started) trying to compile hippocanvas
([1]) for win32.

Actually, I did found a lot of info (in particular, from live.gnome.org
site) about cross-compiling (or compiling under Windows with mingw) gtk
and I think I now learned how to set up a gtk cross-compilation
toolchain; however, I had no chance in finding any hint about
compilation of python gtk bindings for Windows (as is my case).

The only thing I can think about is: cross-compiling python AND THEN
pygtk AND THEN my app. But I'm starting to think this is far too hard
for me (i.e: python wants libc and... well, before july I didn't even
know how to debug a makefile).

Is there anyone able to give me some hints or at least links?

At the moment, the problem I'm fighting with is the following: after
being finally able to run "./configure" with mingw-configure ([2]) (with
gtk dependancies already crosscompiled, but faking Python, pygtk,
pycairo headers, which means just symlinking the ones of the Ubuntu I'm
working on), I get the following:

Actually, I think that the presence of an error in ubuntu's default
stdio.h is quite improbable; can someone help me understand what's going on?

(and/or can someone just clarify to me if that approach has any chance
to succeed?)

thanks
