really really weird, I changed my setup.py to this:
def frameworks(*args):
lst = []
for arg in args:
lst.extend(['-framework', arg])
return lst
module1 = Extension('pysearchkit',
extra_link_args = frameworks
('CoreServices','CoreFoundation'),
sources = ['module.c','index.c']
)
and it worked, I'm still confused as to how that really changes
anything... anyway sorry for the trouble
cheers,
Tom
