Compile on macOS?

[hellisabove]

I'm wondering, how can I compile on macOS?

[Supercip971]

For the moment we don't know how to do it because we don't have a way for testing compilation on macOS :^( .

We provide LLVM compilation, so compiling in macOS should be possible

Install dependencies via Homebrew: brew install qemu nasm xorriso llvm binutils

Fix toolchain paths (hack):

Build and run Brutal: make run CONFIG_TOOLCHAIN=llvm

If you have an x86 Mac, instead of just disabling kvm you can try using hvf for virtualization. But I didn't try.

Update: building brutal on MacOS is now fully supported ;)
