Thank you for the hint. I have checked with "file" command the format of the
libraries on mac and got following result:
one of my application's libraries:
libkkbase.dylib: Mach-O dynamically linked shared library i386
my python module that has been built using standard python distutils:
j3k.so: Mach-O bundle i386
I am not actually sure what's the difference between "bundle" and "dynamically
linked shared library" on mac and if they can be linked together? Perhaps I
should configure distutils on mac somehow specially to make the module ready
for embedding?
Thanks,
KK

I have a problem with linking python module with my application on mac
in order to make the module available in "embedded python".

I link my application with the module and get following linking error
on mac although on open suse linux exactly the same procedure works
fine:
