Arch Linux

Description:
Trying to use a python3 C++-binding, I had the following error:
ImportError: /usr/lib/libboost_python3.so.1.63.0: undefined symbol: PyInit
I then checked the library, and it turns out there are actually lots of undefined symbols in /usr/lib/libboost_python3.so.1.63.0.

This problem occurs because of lack of necessary build flags. For example, python-config --ldflags.


Additional info:
* package version(s): boost 1.63.0
* PKGBUILD with fix in attach
