2001 From: Brett Jia Date: Sat, 8 Feb 2025 15:45:45 -0500 Subject: [PATCH 10/26] Support building cosmocc on MacOS (#1365) This updates the cosmocc toolchain packaging script to work on MacOS. It has been tested on GitHub Actions macos-13 (x86_64) and macos-14 (arm64) runners, and is verified to still work on Ubuntu (GitHub Actions runners ubuntu-24.04 and ubuntu-24.04-arm). It'll help bring cosmocc to MacPorts by running the packaging script. We favor `gmake` rather than the `make` command because it distinguishes GNU Make from BSD Make, and Xcode Make. Additionally, APE loader from the bootstrapper toolchain is used instead of a system APE, which may not be available. --- tool/cosmocc/package.sh | 56 ++++++++++++++++++++++++++++++++--------- 1 file changed, 44 insertions(+), 12 deletions(-) diff --git a/tool/cosmocc/package.sh b/tool/cosmocc/package.sh index 9f9638277..51450e94e 100755 --- a/tool/cosmocc/package.sh +++ b/tool/cosmocc/package.sh @@ -15,17 +15,49 @@ mode() { esac } +_nproc() { + case $(uname -s) in + Darwin) sysctl -n hw.logicalcpu ;; + *) nproc ;; + esac +} + +TMPDIR=${TMPDIR:-/tmp} OUTDIR=${1:-cosmocc} APELINK=o/$(mode)/tool/build/apelink AMD64=${2:-x86_64} ARM64=${3:-aarch64} -NPROC=$(($(nproc)/2)) +NPROC=$(($(_nproc)/2)) GCCVER=14.1.0 -make -j$NPROC m= \ +if !

However, for any given microprocessor architecture, we'll need a separate loader for each operating system. The issue is ELF OSABI isn't very useful. As an example, SerenityOS and Linux both have SYSV in the OSABI field. So to tell their binaries apart we'd have to delve into various other conventions, like special sections and PT_NOTE structures. To make things simple this change introduces the `-k OS` flag to apelink which generate shell script content that ensures `OS` matches `uname -s` before attempting to execute a loader. For example, you could say: apelink -k Linux -M blink-linux-arm.elf -M blink-linux-mips.elf \ -k Darwin -M blink-darwin-ppc.elf \ ...
