Pynac depends heavily on Sage. Some code that really belongs to Pynac
is actually in the Sage library. It is impossible to use Pynac without
that part. Are you planning to package Sage as well?

I'll see what I can do about this.

I tried these. Here's my approximation:

https://bitbucket.org/burcin/pynac-wip/src/d33822b5a822

After removing INCLUDES, it wasn't enough to add libpynac_la_CPPFLAGS.
I got errors about missing Python.h when compiling .cpp files. So I
added a line CPPFLAGS = $(PYTHON_CPPFLAGS) instead of
libpynac_la_CPPFLAGS.

Note that I am a complete auto* newbie. If you're OK with this change,
I will commit it to the main repository.


Thanks for your help.

Hmm.. it worked for me too. I don't know what I messed up last time.

The work-in-progress repo contains the libpynac_la_CPPFLAGS line. I
will push this to the main repo if there are no compaints.


Thanks.
