You were looking at the wrong manual. Read http://docs.python.org/distutils/setupscript.html#preprocessor-options Extension(..., define_macros=[('NDEBUG', '1'), ('HAVE_STRFTIME', None)], undef_macros=['HAVE_FOO', 'HAVE_BAR']) Note that define_macros requires a list of tuples each having two members.
