This macOS arm64 example links a scriptc program object, a small C FFI implementation, and the exact installed source runtime pack. It uses no scriptc cache path.
$ clang -target arm64-apple-macosx14.0.0 -O2 -c native.c -o native.o
$ scriptc build main.ts --ffi ffi.json --print=native-link-info -o app.o > link-info.json
$ node link.mjs cc link-info.json app-cc
$ ./app-cc
42
$ node link.mjs ld link-info.json app-ld
$ ./app-ld
42cc uses the C compiler as a linker driver. ld compiles the same reported
runtime sources and invokes the Apple linker directly with the selected SDK.
The object defines main; it is a complete program object, not a library to
load into another process. Use scriptc build --lib --profile ... for a
host-callable static library.
The external object ABI is experimental. Always consume the runtime pack at
the exact runtime_pack.version reported by the same scriptc installation.
The object requires scr_runtime_abi_v1, so a mismatched runtime fails during
the link instead of starting with an incompatible ABI.
