Wrapping C functions in Pyrex and distutils problem

[TPJ]

I'm trying to get a wrapper for my C code in order to be able to use it
as a module in Python. I'm doing it as follows:

C code (file_c.c):
-------------------------------
#include <stdio.h>

void hello( int size )
{
printf("Hello! %d\n", size);
}
-------------------------------

Pyrex code (file.pyx):
-------------------------------
cdef extern void hello( int size )
-------------------------------

Python code (setup.py):
-------------------------------
from distutils.core import setup
from distutils.extension import Extension
from Pyrex.Distutils import build_ext

setup(
name = "File",
ext_modules=[
Extension( "file", ["file.pyx", "file_c.c"] )
],
cmdclass = { 'build_ext': build_ext }
)
-------------------------------

After

$ python setup.py build_ext --inplace

all is compiled ok, but the shared library (file.so) is built only from
one file (file_c.o) - and the second object file (file.o) is ignored.
Of course it's imposible to import such a module in Python.

What am I doing wrong?

Use additional_objects:
--------
LINKBASE = "link-4.1b"

setup(
name = "LinkWrapper",
ext_modules = [
Extension("link", ["link.pyx"],
include_dirs = ["%s/include" % LINKBASE],
extra_objects = glob.glob("%s/obj/*" % LINKBASE),
)
],
cmdclass = {'build_ext': build_ext}
)
---------
