hi there, i've been try to build this project so i instaed the llvm, lld, python, gcc, cmake, from brew.sh but the llvm-objcopy is for arm64 and my machine is X86 - X64 so is there anyway to work around this ?

@relalis commented on GitHub (Nov 9, 2024):

I'm in the process of rewriting this kext, and have been focusing on FreeBSD because it's faster to test in a kpanic. The reason you're failing to build it is because there's nothing to build for a macOS target; if you're expecting a functional BTRFS driver, this is unlikely to be your project (unless you get really lucky and I stop being lazy)

I have some commits I'd like to push for basic VFS reading but my build server lost its PSU and I'm unfortunately traveling; give me a couple of weeks.

Ok, but they didn't mention this project doesn't support X86_x64 machines recently at least. Thanks for responding

I don't believe I have any architecture-specific code. The FreeBSD module is targeted at x86_64 and the macOS module will as well.
