I found the cheribuild ( https://github.com/CTSRD-CHERI/cheribuild ) script to build a cross compiler, vm image, and CHERI riscv emulator to be very easy to use and effective.

My code mostly compiled on CHERI without issue-- I was hoping to find some interesting bug as that's a pretty realistic prospect when porting to CHERI but didn't do so on the code I've tried so far.
