I knew from the beginning that the mining tools would be the hardest to 
port. For this reason, I don't hold out much hope that we will ever get 
XMRig and P2Pool working on OpenBSD. On the other hand, looking at the 
RandomX code, you can already see that this port will not work on any 
platforms other than those supported by the Monero project on Linux, 
which are amd64, i386, arm64, armv7, and riscv64.
