Building modules with Distutils (1)

Python has a tool, Distutils, for compiling and linking extension modules

First write a script setup.py:

import os
from distutils.core import setup, Extension

name = 'hw'           # name of the module
version = 1.0         # the module's version number

swig_cmd = 'swig -python -I.. %s.i' % name
print 'running SWIG:', swig_cmd
os.system(swig_cmd)

sources = ['../hw.c', 'hw_wrap.c']

setup(name = name, version = version,
      ext_modules = [Extension('_' + name,  # SWIG requires _
                               sources,
                               include_dirs=[os.pardir])
                     ])
