[Pyrex] How to use function defined in C-file?

[Tomasz Primke]

Hello.

I'm trying to make a module that uses a function defined in external C-file:

test00.pyx:
---------------------------
cdef extern void hello( int size )
---------------------------

test00_c.c:
---------------------------
#include <stdio.h>

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

setup.py:
---------------------------
import glob
from distutils.core import setup
from distutils.extension import Extension
from Pyrex.Distutils import built_ext

TESTBASE = "build/temp.linux-i686-2.4"

setup(
	name = "Test",
	ext_modules = [
		Extension( "test00", ["test00.pyx", "test00_c.c"],
			   extra_objects = glob.glob( "%s/*" % TESTBASE )
			)
		],
	cmdclass = { 'build_ext': build_ext }
	)
---------------------------

The module is built as follows:

$ python setup.py build_ext --inplace

The only problem is that when I run Python and import this module, no 
functions are available (there's no hello function):

>>> import test00
>>> dir(test00)
['__builtins__', '__doc__', '__file__', '__name__']

I'm using Python 2.4.1 (but the version 2.4.2 will be also used) and Pyrex 
0.9.3.1. What am I doing wrong?
