Hi @danrmiller, the armv8 build needs miniupnpc.

Edit: also, the armv7 build was never triggered

Have you seen how we detect arm and crypto options in monero'a CMakeLists.txt?

I know asking the compiler isn't ideal, but even the guys behind MBED find it hard to properly define the target architecture because AFAIK for some reason ARM keeps the internal options register protected

@NanoAkron yes but I'm not sure how that's relevant now (crypto impl is currently handled by external libraries). What exactly do you mean? Lib-side compiler fine tuning can come later - after we get the builds running (or if someone else wants to get involved now).

ARMv8 build is currently failing because of No space left on device. pigeons and host provider are currently working on a fix.
