Debian 12 Zig cross toolchain
The production native-build path is the pinned Debian 12 image plus Zig 0.14.1, covering all nine GNU Linux, musl Linux, Windows and macOS targets. musl uses checksum-locked target sysroots inside the same Debian image.
Read CROSS-COMPILE.md for current build commands, exact local validation scope and remaining Docker/runtime/NativeAOT verification. Read DAILY-RELEASE.md for daily 3/4 release configuration.
Dockerfile pins the base digest, apt snapshot and source-preparation tools.
Dockerfile.cross-probe adds Zig, macOS SDK, Windows headers, target Linux SDKs
and .NET SDKs. The historical filename is retained for existing references.
zig-toolchain-image.yml reuses recipe-tagged GHCR images and downstream jobs
pull their immutable digest. Source locks and archive/link manifests provide
traceability. No complete local Docker image build has been run.
Legacy platform helper scripts are retained for reference; production graphics Actions now delegate to the common Zig cross-build workflow. SkiaSharp 2 remains outside the new daily tracks.
