Hi guys, Has anyone been successful compiling xtherion on a Mac with the M1 chip and Big Sur ? I can compile and run therion but I have the following error message and fail to compile xtherion : extern/catch2/catch.hpp:8205:13: error: unrecognized instruction mnemonic, did you mean: bit, cnt, hint, ins, not?
