Suggested-by: Masahiro Yamada Tested-by: Jeff Xie Signed-off-by: Daniel Gomez --- This patch allows for building the Linux kernel for arm64 in macOS with LLVM. macOS does not provide certain headers that are available in a GNU/Linux distribution with development headers installed, usually provided by the GNU C Library (glibc) and/or other projects. These missing headers are needed as build dependencies. To address this, users need to provide these headers manually. To assist with provisioning and setting up the environment, the Bee Headers Project [1][2][3] provides the necessary headers, along with a pkg-config file to locate the include directory and an initialization script to configure the environment. However, this is optional and users can choose to set up their own environments and manually provide the required headers. In that case, the project can be used as a reference. Here=E2=80=99s a quick overview of the setup process using Bee Headers: Set up a case sensitive volume to fetch Linux and build: diskutil apfs addVolume /dev/disk "Case-sensitive APFS" linux =09 Install dependencies: brew install coreutils findutils gnu-sed gnu-tar grep llvm make pkg-config brew tap bee-headers/bee-headers brew install bee-headers/bee-headers/bee-headers Initialize the environment with `bee-init` and run it in each new shell: source bee-init =09 Start build: make LLVM=3D1 defconfig make LLVM=3D1 -j$(nproc) For more details and manual steps, refer to the README [4] of the Bee Headers project.

User requires to set up this in the build environment with something like: export HOSTCFLAGS=3D"-D_UUID_T -D__GETHOSTUUID_H" - Drop documentation patch. Environment setup and headers should now be provided by the user. The project Bee Headers can be used to help with the steps and documentation. - HOSTCFLAGS should be used to provide the missing headers as well as the above defines. Example using Bee Headers: export HOSTCFLAGS=3D"$(pkg-config --cflags bee-headers) -D_UUID_T -D__GETHOSTUUID_H" - PATH needs to have all tools the kernel build system depends on. Something like this: PATH=3D"#{HOMEBREW_PREFIX}/opt/coreutils/libexec/gnubin:$PATH" PATH=3D"#{HOMEBREW_PREFIX}/opt/findutils/libexec/gnubin:$PATH" PATH=3D"#{HOMEBREW_PREFIX}/opt/gawk/libexec/gnubin:$PATH" PATH=3D"#{HOMEBREW_PREFIX}/opt/gnu-sed/libexec/gnubin:$PATH" PATH=3D"#{HOMEBREW_PREFIX}/opt/gnu-tar/libexec/gnubin:$PATH" PATH=3D"#{HOMEBREW_PREFIX}/opt/grep/libexec/gnubin:$PATH" PATH=3D"#{HOMEBREW_PREFIX}/opt/make/libexec/gnubin:$PATH" PATH=3D"#{HOMEBREW_PREFIX}/opt/llvm/bin:$PATH" - Drop patches below as they've been replaced by a new 2nd version [8]: selinux: move genheaders to security/selinux/ selinux: do not include headers from host programs [8] Subject: [PATCH v2 1/2] selinux: do not include headers fro= m host programs https://lore.kernel.org/all/20240906172934.1317830-1-masahiroy@kernel.org/#t Note: This has been specified as dependency with b4 and message-id in the cover letter. - Link to v2: https://lore.kernel.org/r/20240906-macos-build-support-v2-0-0= 6beff418848@samsung.com Changes in v2: - Add documentation and set this 'feature' as experimental. - Update cover letter. - Drop unnecessary changes.
