Cannot build on macOS BigSur version11.6 about cup HOT 2 CLOSED

Actually, it was a simple enough fix. I've updated the code to use clang for linking on macOS, and I've also added a test runner for macOS 11 to make sure we don't regress. If you just checkout the newest master, it should work fine now on your machine. Thanks again for taking the time to point out the bug!

The issue here is that the first round of compilation is happening successfully with the flags you passed in, but internally, the bootstrap compiler also calls ld to link the new executable, but the flags are not being passed in there unfortunately. For now, you can just link build/cupcc.o manually, and edit compiler/main.cup to include the new flags to the ld call, and then run compile a newer version of the compiler.

Perhaps the better fix here might be to just use clang for linking as opposed to ld, and it will pass all the correct arguments to the linker call. Changing the linking step to clang XXX.o -o XXX (in both the meta/bootstrap.sh file and compiler/main.cup) seems to do the trick for me, but I'm not sure if that might be different on your version.

Thanks for pointing this out, I didn't know there would be weird stuff with different macOS versions, I'll look into this further, and see if I can push a change to the repo within the next few days that just lets it work out of the box. I think Github Actions has macOS 11, so I might be able to test there.

It's a bit of an annoyance getting the initial workflow up, but after that it's usually fine. You can reach out on Discord if you're still interested in getting it working and want some help: mustafaq#8791
