[Pyrex] problem building simple package with extensions in Windows, but not OS X

[Brian Blais]

Hello,

I am trying to build a package of mine, and for some reason the build  
process with distutils is failing in Windows, but not in OS X (and I  
imagine also in Linux, but I haven't tested it).  I am not sure if  
this is a Pyrex problem, a distutils problem, or me doing something  
stupid problem.  :)

I boiled it down to the simplest package that still fails.  My  
setup.py is:

from distutils.core import setup
from distutils.extension import Extension
from Pyrex.Distutils import build_ext

setup(
   name = 'myproject',
   version='0.0.1',
   description="Here is a description",
   author="Brian Blais",
   ext_modules=[
     Extension("myproject/train",["myproject/train.pyx"]),
     ],

   packages=['myproject'],

   cmdclass = {'build_ext': build_ext}
)



and my project has one directory, myproject, with two files.   
train.pyx is:

def func(blah):

     print blah


and an __init__.py, which has the single line:

import train


So, in OS X, I can do

python setup.py build

and the build goes through.  In windows, with the same basic setup  
(version numbers all below), I get:

[Desktop\test]|5> !python setup.py build

\myproject/train
.pyd
Cannot export initmyproject/train: symbol not defined
collect2: ld returned 1 exit status
error: command 'gcc' failed with exit status 1



On both the Mac and the PC I have:

Python 2.5.1
Pyrex version 0.9.5.1a
distutils 2.5.1



am I doing something wrong?


		thanks,
