Although I have been able to compile Xmrig on my Rpi 4, none of your recent crypto builds worked. I finally was able to purchase an Rpi 5 from Adafruit and will try again.
I have several Orange Pi 5 boards mining Verus coin. I'll be able to check the Rpi 5 hashrate in comparison.
I think I missed this point. The Windows builds won't work on RPI or OPi, they're for X86_64 not Arm.
If you have problems compiling on RPi (or OPi) with Linux it's probably missing packages. It may depend on how you install Linux.
If you installed from an custom image file it may not have all necessary packages. I installed using using normal installation
procedure for Ubuntu using the Arm server ISO and had no issues compiling afterward.
