使用Cython将metis链接到包装的C ++模块

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

Answer 1

我找到了解决此问题的方法，而不是使用distutils，而是使用makefile进行编译，这使链接更加容易。

Answer 2

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.
