Can't compile unit test on Apple M1 #701

Closed catap closed 2 years ago

catap commented 2 years ago

When I try to compile box2d on apple m1, I have tonns of errors like this:

/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_box2d/box2d/work/Box2D-2.4.1/unit-test/math_test.cpp:43:3: error: unrecognized instruction mnemonic, did you mean: bit, cnt, hint, ins, not?

This is clear that embedded unit-test aren't compatible with M1.

I updated doctest. Please let me know if you still have problems. Unfortunately github actions don't support M1 CI yet.
