ARM support request #200

Closed alexellis closed 7 years ago

alexellis commented 7 years ago

Could you support ARMv6 or ARMv7 even if it meant removing the optimizations in assembly.

I have a farm of Raspberry Pi 2 and 3 and can run almost any algorithm through CPUMiner, just not Equihash.

robertfoss commented 7 years ago

Adding a generic non-ASM equihash implementation should be pretty straight forward. After all it already exists in the mainline zcash implementation.

alexellis commented 7 years ago

I couldn't find the g++-multilib package for Raspbian, but yes an implementation would be great for ARM.

Actually.. building overnight through my Dockerfile I got an error with g++ during build time. How did you manage to build zcash/zcash on ARM @robertfoss ?

@alexellis there is a fork from kost that has support for ARM (Raspberry PI). This fork is focused on CPU mining so this should do for now.

alexellis commented 7 years ago

Thanks.. I did try that and it was (as expected) not effective as finding shares. Do you have anything that supports ARM64?
