[Pyrex] [newbie] first error : "init function"

[Jean-Baptiste Richet - AREAS]

Hi,

I'm trying pyrex to use my C functions into new jobs I want to implement 
in python ('cause it's nicer). I'm working on a linux box for the while.

I wrote my .pyx file, mostly imitating the pyxcups.pyx given by Michael 
JasonSmith, and using distutils. It compiles, but when trying to import 
the module in python, it clames for an init function !?
Here are the messages :

================================

Here is my very simple .pyx file :
============= pro_auget.pyx ============
cdef extern from "pro_auget_pyx.h":
    ctypedef struct Tps:
        int tps_10e
        int tps_sec
        int tps_min
        int tps_h
        int tps_j
        int tps_m
        int tps_year

    int decomp_date(double t, Tps* pdate)

def py_decomp_date(t):
    cdef Tps date
    retour = decomp_date(t,&date)
    print "%2d/%2d/%4d %2d:%2d:%2d,%1d\n" % 
(date.tps_j,date.tps_m+1,date.tps_year+1900,date.tps_h, date.tps_min, 
date.tps_sec, date.tps_10e)
====================================

Maybe the confusion comes from my setup.py file (imitating the demo's as 
well, without realy understanding)... here is it:
=============== setup .py ==============
from distutils.core import setup
from distutils.extension import Extension
from Pyrex.Distutils import build_ext
setup(
  name = "py_pro_auget",
  ext_modules=[
    Extension("py_date", ["pro_auget.pyx", "date.c"])
    ],
  cmdclass = {'build_ext': build_ext}
)
=====================================

It is probably a very stupid error, but I understand too few things to 
find it out.
Thanks a lot for your help.
