[Swig-user] Help needed to compile generated C Python module

[Raffaele S. <raf...@gm...>]

I'm trying to build a Python extension around Linux Wireless Extension
You can download the WE sources here
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/wireless_tools.29.tar.gz

The file I need to wrap is iwlib.h, so I wrote this interface file
NOTE: you have to remove __attribute__ ((packed))

/* iwlib.swig */
%module wireless
%{
#include "iwlib.h"
%}
%include "iwlib.h"

then run swig. I got iwlib_wrap.c, then I tried to compile it this way
$ python setup.py build_ext --inplace
running build_ext
building '_wireless' extension
gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall
-Wstrict-prototypes -fPIC -I/usr/include/python2.6 -c iwlib_wrap.c -o

I also tried a different interface file (without the %include, BTW
what's the need for both #include and %include?)
/* iwlib.swig */
%module wireless
%{
#include "iwlib.h"
%}
this way the wrapper C file gets compiled without errors, but then I
can't use any function in the wireless python module. Here is my
setup.py

#!/usr/bin/env python
from distutils.core import setup, Extension

wirelessModule = Extension("_wireless",
		sources = ["iwlib_wrap.c"],
	)

setup(
		name = "wireless",
		author = "Raffaele Sgarro",
		version = "0.1",
		ext_modules = [wirelessModule],
	)

So can you show me the way for getting a Python module from iwlib.h?
