I did get an ARM version running. I can dust off the builder that I used to get it running. It actually wan’t too difficult, just took a few hours to compile if I remember.
Well, the compile time is related to the arm structure of the pi, which is emulated in Travis.
If I remember right , @uncle_muddy compiled on a hardware Pi and it took more than a day to compile…
Can’t you just configure the Travis containers to keep the compiled binaries and feed the code to Travis again? I’ve seen somewhere, that it is possible to keep the created files in Travis
