This patch set allows for building the Linux kernel for arm64 in macOS with
LLVM.
Patches are based on previous Nick's work and suggestions [1][2][3] to
enable build system in macOS hosts.
Since macOS does not provide some of the headers available in the GNU
C Library (glibc), the patches include a copy of these headers from
glibc-2.40, with minor modifications detailed in the commit message.
To set up the environment:
* Provide build dependencies (installed via Homebrew):
coreutils, findutils, gnu-sed, gnu-tar, grep, llvm, make and pkg-config.
* A case sensitive volume for building:
diskutil apfs addVolume /dev/disk<N> "Case-sensitive APFS" linux
* And include in your PATH all GNU tools required by the Linux kernel as
well as LLVM:
PATH="/opt/homebrew/opt/coreutils/libexec/gnubin:$PATH"
PATH="/opt/homebrew/opt/findutils/libexec/gnubin:$PATH"
PATH="/opt/homebrew/opt/gnu-sed/libexec/gnubin:$PATH"
PATH="/opt/homebrew/opt/gnu-tar/libexec/gnubin:$PATH"
PATH="/opt/homebrew/opt/grep/libexec/gnubin:$PATH"
PATH="/opt/homebrew/opt/make/libexec/gnubin:$PATH"
PATH="/opt/homebrew/opt/llvm/bin:$PATH"
* Start the build using LLVM:
make LLVM=1 allyesconfig
make LLVM=1 -j$(nproc)
I believe other architectures could also be supported if we can move
forward this initiative. Additionally, we could incorporate Rust
support. I understand that Finn Behrens has some patches [4][5] based on
Nick's previous work.
