how to add library compilation to numpy.distutils.core?

how to add library compilation to numpy.distutils.core?

I'm trying make setup.py for my tiny module, which uses numpy. To compile
this module I need extra library which locates in same directory
ls -l audiotools
total 20
-rw-rw-r-- 1 rth rth 4405 Sep 9 10:58 audiotools.c
drwxr-xr-x 6 rth rth 4096 Sep 9 11:13 libresample-0.1.3
-rw-rw-r-- 1 rth rth 741 Sep 9 11:56 setup.py
So I need add something in setup.py which call configure and make in
libresample-0.1.3 and then add 'libresample.a' to the linker command.
I've tried used add_library, but it requires just source files but not
whole source directory. How I can do it?
This doesn't work.
def configuration(parent_package='', top_path=None):
import numpy
from numpy.distutils.misc_util import Configuration
config = Configuration('audiotools',parent_package,top_path)
config.add_extension('audiotools', ['audiotools.c'])
config.add_library('libresample',['libresample.a'])
return config
if __name__ == "__main__":
from numpy.distutils.core import setup
setup(
name = "audiotools",
version='0.01',
description='Python wrapper for GNU libresample-0.1.3 and
reader of Wave 24bit files',
author='Ruben Tikidji-Hamburyan, Timur Pinin',
author_email='rth@nisms.krinc.ru, timpin@rambler.ru',
configuration=configuration
)
Thanks!
