Thank you @cryptonemo yes, the build can go through. I also need to set the CGO_LDFLAGS="-g -O2 -L/opt/homebrew/lib". Thank you :)

I'm not on MacOS, but from the error message it seems that you don't have the x86_64-apple-darwin target installed (I also don't know if you can cross-compile on an M1). Though, could you please try to install that target via rustup target add x86_64-apple-darwin and see if that makes it work?

Thanks @vmx for the help. I had already run rustup target add x86_64-apple-darwin, but that added this target in the default toolchain which was not the specific nightly version used by filecoin-ffi (it was the stable toolchain). So I re-added the above target after having set the specific toolchain as default and at least proceeded.
But I got stuck on the following error then:
Compiling merkletree v0.21.0
error: could not find native static library `ff-derive-crypto`, perhaps an -L flag is missing?
error: aborting due to previous error
error: could not compile `fff`
To learn more, run the command again with --verbose.

The commit you're using is still a WIP, so it could well be there are problems. Could you try the latest commit from #192?

Ah, ok I now used the commit: 84aedba415038e6046aebabecfd7406933c7f547, I still ended up getting those errors.
Removing the target x86_64-apple-darwin from this line at least allows me to proceed with the compilation without the above error.
When using the cgo generated files, the hwloc library cannot be found:
ld: library not found for -lhwloc
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have already installed the hwloc formula using brew install hwloc:
$ brew info hwloc
hwloc: stable 2.5.0 (bottled), HEAD

Try to build on the current filecoin-ffi master branch.
The build.sh script may not work if you don't have the OS X build targets, so you can install them manually if needed:
rustup target add x86_64-apple-darwin --toolchain $(cat rust-toolchain)
rustup target add aarch64-apple-darwin --toolchain $(cat rust-toolchain)
Then build ffi like:
LIBRARY_PATH=/opt/homebrew/lib LDFLAGS="-framework OpenCL" make clean
LIBRARY_PATH=/opt/homebrew/lib LDFLAGS="-framework OpenCL" make
