Any other ideas on how to solve this in a better way? Have you tried with distutils2? If it can't help you, it should really be looked into before the packaging API is locked for 3.3.

distutil2 is almost identical to distutils as far as compilation goes, so I am not sure why it would help the OP.

@Lukas: if you want to check for compiler flag support, the best way to do it in distutils is to use the config support: look in particular in the try_compile/try_link methods. The schema is basically:

code may refer to e.g. a trivial extension source code

try_compile(code) # check that the current option set is sane for each additional flag you are interested: save compiler option add the additional flag if try_compile(code) == 0: restore compiler option

cheers,

David
