I found that setting C_INCLUDE_PATH as you did disables finding libffi headers since pkg-config prints nothing with pkg-config --cflags libffi then and it seems the headers are found with pkg-config. As for the libraries, detect_modules() in setup.py wants to find extra library directories from the generated makefile so you need to make sure they actually go in there, like this for example: LDFLAGS=`pkg-config --libs-only-L libffi` ./configure Then you'll have CONFIGURE_LDFLAGS and PY_LDFLAGS set in the generated makefile and setup.py will pick up the directory from there. Anyways, hope it helps. This worked for me on Ubuntu 16.04.5 LTS. -- https://mail.python.org/mailman/listinfo/python-list
