Problem with linking embedding C application

[Olivier Deme]

Hi,

We have written an application written in C, which invokes sometimes the Python 
interpreter for executing Python methods.

So, I am trying to statically link our application with libpython*.*.a., but this result in various 
undefined symbols (see below).

Now, it looks like I am missing symbols defined in the math and posix thread library! I don't
understand this since we are not using any symbols defined in these libraries.
Could anybody tell me what is going on and how I can fix this problem?

Thanks!
