Hi! simply copying a new Makefile target doesn't grants portability per se. Have you tried it on RISC-V? Let us know!

Yes, I've tried on Bananpi-F3, which runs perfectly.

Hello, World!

[jaromil]

awesome! do you mind also running make check and sharing here the output? I will add a CI build to release riscv binaries too.

[mengzhuo]

Sure
