Linking metis to wrapped C++ module using Cython

Question

I am trying to link the metis library during the compiling of the Cython source file but I am having difficulties as I am getting undefined symbols in the compiled shared object file.

I was wondering if anyone had any experience with linking external libraries such as metis using distutils? Would a better option be using makefile?

What I have done:

Adding the directory to libmetis.a in extra_link_args

If you put your setup.py file in your post it might help to answer. Plus a little sketch of the (cython) code you are compiling. — Cristián Antuña, Mar 26 '15 at 13:28

I found a solution to this issue which is instead of using distutils, I used makefile to compile which makes the linking much easier.

So the original OP saying he's solved his problem is not an answer to the question? How do you reckon that? – David van Driessche May 03 '15 at 14:34

Probably you need

python setup.py build_clib

before

python setup.py build_ext --inplace

If this doesn't help, is the undefined symbol _Py_ZeroStruct ? That would be because you did python setup.py build_ext and used from python 3. For that, you'll need python3 command.

Hope this helps.
