magiskboot

Standalone build of magiskboot from topjohnwu/Magisk - no app, only the native boot image tool.

What it does

• Clones upstream Magisk (shallow) nightly + on manual dispatch
• Builds only magiskboot via build.py native magiskboot (Rust + NDK)
• Publishes static binaries for all Android ABIs

Binaries are fully static (-static, musl tiny printf when B_CRT0=1) - run on device via adb or in recovery.

Build locally

git clone https://github.com/topjohnwu/Magisk.git upstream
python upstream/build.py ndk          # one-time: downloads ONDK r30.1 to $ANDROID_HOME/ndk/magisk
python upstream/build.py -vr native magiskboot
ls upstream/native/out/*/magiskboot

Or via helper:

./scripts/sync.sh            # clone/update upstream + build
./scripts/build.sh           # build only (expects ./upstream present)

CI

• Workflow: .github/workflows/build.yml
• Triggers: nightly 03:00 UTC cron, workflow_dispatch (manual), push to main
• Artifacts: magiskboot-<abi> + magiskboot-all.tar.gz

Roadmap

• Host builds: x86_64 Linux exe, macOS arm64/x86_64, Windows exe (cross via cargo + mingw)
• Current workflow has placeholders (matrix disabled) - enable when NDK host cross is verified
