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. Assisted-by: Claude:claude-opus-4-8 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Co-authored-by: Ettore Di Giacinto <mudler@localai.io>
