Hi escalade!
Can you describe your building process?
I downloaded your last source code(2020-11-24) then I built xenial docker image from tools/docker/xenial/Dockerfile. I ran the command "PROJECT=Generic ARCH=x86_64 DISTRO=RetroELEC make" in this image and had a lot of building errors. The googling helped me solve some errors but I stuck with python3 _ctypes module now.
All in all, I want to repeat your building process and then add my small changes.
I very like your project, thank you very much for it
