How can I run a Makefile in setup.py?

Question

I need to compile ICU using it's own build mechanism. Therefore the question:

How can I run a Makefile from setup.py? Obviously, I only want it to run during the build process, not while installing.

Answer 1

The method I normally use is to override the command in question:

from distutils.command.install import install as DistutilsInstall  class MyInstall(DistutilsInstall):     def run(self):         do_pre_install_stuff()         DistutilsInstall.run(self)         do_post_install_stuff()  ...  setup(..., cmdclass={'install': MyInstall}, ...) 

This took me quite a while to figure out from the distutils documentation and source, so I hope it saves you the pain.

Note: you can also use this cmdclass parameter to add new commands.
