OpenAGRO:
The problem is that, even when he has no problems running the firmware in the exactly same components, I just cannot compile it. The coding errors seem to be very simple, but I just cannot fix them.
No matter how simple the coding errors seem to be, you keep them secret, and nobody will ever be able to help you until they know what they are. Assuming that the code is indeed kosher, the problem probably has more to do with where the libraries are kept than what they are.
