Can you help me? > GCC 7 is no longer supported or maintained, so it's not going to get updated to work on the new Apple M1 systems. GCC 10 is the oldest release series that will work on M1 right now. You should try to reach out to the MESH folks for a solution (it might be that it would run under Rosetta 2 - so that intel install can be made on the M1) - of course that’s not going to be the best performance. Or maybe they can fix it to make it work with a recent GCC.
