MMDVMHost failed on Le Potato


I’m following MMDVMHost on a Le Potato – N2VDY: Amateur Radio and Compilation of an MMDVMHost from G4KLX, independent of Pi-Star. – G4NAB to set up the MMDVM service on Le Potato. Something bumped in last minute.
I would think it is more related to MMDVMHost but not Le Potato. Anyone got it done in the past? Any idea?

Seems it is almost there…

Solved. make clean MMDVMHost. Don’t choose Makefile.Pi.I2C at the timepoint, but go straight to make Makefile. The essential problem is with the wiringPi lib.
