`docker/macos` builds for aarch64-apple-darwin from Linux with cargo-zigbuild. Zig carries libSystem and the C headers, so tract's SIMD kernels compile and the engine's test binaries and examples link as Mach-O arm64 — the check `cargo check --target` could not do, because tract's build script needs a macOS C compiler. Crates that link an Apple framework (dr-plat's keyring, and so the app) still need the Xcode SDK and fail at the link; macos.md says so.

# DarkRoom — macOS link check

|
# Compiles and links for macOS from Linux, with zig as the linker
|
|
# (cargo-zigbuild). Zig carries macOS's libSystem stubs and C headers, so the
|
|
# crates that need only libSystem — the inference engine, dr-plat — build,
|
|
# link and produce Mach-O test binaries here. Nothing runs: there is no macOS
|
|
# to run them on (docs/dev/macos.md §2). The desktop app needs Apple's
|
|
# framework headers (AppKit, Metal, Security), which only the Xcode SDK
|
|
# carries, so it does not link here.
|
|
#
|
|
# Build: docker build -t darkroom-macos:latest docker/macos
|
|
# Use: ./docker/macos/build.sh cargo zigbuild --target aarch64-apple-darwin -p dr-inference-engine --all-targets
