fix(ci): resolve macOS aarch64 build (gexiv2/gobject linking)#2
Merged
Conversation
The gexiv2_metadata_free shim must live in lib.rs, not main.rs, because Cargo builds all declared crate types (staticlib, cdylib, rlib) and macOS's linker rejects undefined symbols in cdylib targets. Placing the shim in main.rs only satisfied the final binary link, not the cdylib step. Drop macos-13 from the build matrix: Intel GitHub-hosted runners are deprecated and removed on 2026-06-16; the last run queued 24h without ever getting a runner. ARM64 binaries run on Intel Macs via Rosetta 2. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The gexiv2_metadata_free shim in lib.rs calls g_object_unref, which lives in libgobject-2.0. gexiv2 lists gobject only under Requires.private, so pkg-config omits it from the dynamic link line and the symbol is left undefined at link time on macOS. Probe gobject-2.0 via pkg-config in build.rs and emit an explicit link directive, gated on the target OS. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
