The opus Go backend (WebRTC audio codec) never built on macOS, so the
published master-metal-darwin-arm64-opus image shipped source only — no
opus binary and no libopusshim — because every step assumed Linux.
- Makefile: hardcoded libopusshim.so with no OS handling. Mirror
sherpa-onnx: SHIM_EXT=so / dylib on Darwin and build
libopusshim.$(SHIM_EXT). On Darwin link the shim with
-undefined dynamic_lookup so it resolves opus_encoder_ctl from the
already globally-loaded libopus (codec.go dlopens it RTLD_GLOBAL
first) instead of baking an absolute Homebrew path into the dylib,
keeping the packaged shim relocatable.
- run.sh: hardcoded LD_LIBRARY_PATH + libopusshim.so even on macOS. Add
a Darwin branch exporting DYLD_LIBRARY_PATH and the .dylib shim, like
sherpa-onnx/run.sh.
- package.sh: bundle libopusshim.$(SHIM_EXT) and libopus*.dylib (not
just .so) into package/lib so the OCI image (which ships package/.)
is self-contained on a runtime with no Homebrew; add a Darwin arch
branch so it doesn't warn/skip.
- backend_build_darwin.yml: install + link opus and pkg-config via brew
so the Makefile's `pkg-config opus` resolves on the macOS runner, and
cache opus' Cellar dir.
Go code is unchanged; darwin build is validated in CI.
