I need to have my python have access to UPnP, and have been working with miniupnpc to make that happen. Installing via pip has a vague error message; so I expanded the storage of my Onion Omega2, installed make and gcc, and attempted to build the package myself. When running python setup.py build_ext, I get the following output (slightly formatted for easy reading):

[NOTE: I've tried this before, so some of the build process is already done. I don't know how to force a full rebuild.]

running build_ext
make: 'libminiupnpc.a' is up to date.

I'm trying to find out how to solve this problem in ld, but nothing is coming up in my searches. Has this been a problem for anyone else compiling Python packages locally on the Onion? What is the right format for the system? Is there a way to force the build to use the format OnionOS wants?
