Three coupled fixes that close the macOS bring-up loop:
## 1. ifcwrap: fix INSTALL_RPATH on Apple
The ifcopenshell_wrapper Python module had `INSTALL_RPATH "$ORIGIN"` set
for "NOT WIN32 AND NOT WASM_BUILD" — but `$ORIGIN` is a Linux ld.so
placeholder, not a macOS dyld one. macOS dyld doesn't expand it; it
bakes the literal string `$ORIGIN` into LC_RPATH, which resolves to
nothing at runtime. The wrapper's hard-link `@rpath/ifcopenshell
.document.rdb.dylib` then fails to load even though INSTALL(TARGETS …
LIBRARY DESTINATION "${python_package_dir}/ifcopenshell") above had
already dropped the plug-in dylib right next to the wrapper.
Split the rpath assignment: `@loader_path` on Apple (the dyld
equivalent of `$ORIGIN`), `$ORIGIN` elsewhere.
This is what b0ef47819 (the build_osx IFCOS_BUILD_PYTHON_WRAPPER=off
gate) was working around. The gate is removed below.
## 2. ifcviewer-minimal: stage IfcOpenShell + wgpu_native into the .app
IfcViewerMinimal.app was building on macOS via the cmake
`BUILD_BONSAIVIEWER → BUILD_BONSAIVIEWER_WGPU` promotion, but had no
bundle staging — Contents/Frameworks/ only contained the Qt
frameworks macdeployqt deposited, so the .app would refuse to start
("Library not loaded: @rpath/libwgpu_native.dylib").
Mirror what src/bonsaiviewer/CMakeLists.txt does for BonsaiViewer.app:
* Set INSTALL_RPATH to `@executable_path/../Frameworks` so the exe
knows where to look for @rpath/* deps.
* install(FILES) libwgpu_native.dylib into the bundle's Frameworks/
(globbed from WGPU_NATIVE_LIB_DIR rather than hard-coded so it
covers any future versioned name).
* install(CODE) staging block that copies every `*.dylib` from
<prefix>/lib/ into the bundle's Frameworks/, excluding the
geometry-writer plug-ins (same EXCLUDE regex as BonsaiViewer.app —
viewer doesn't need OBJ/glTF/DAE/STP/IGS/SVG/TTL export converters).
Same long-form rationale + caveats apply (macdeployqt doesn't follow
non-Qt @rpath deps, lib-prefixed core libs vs ifcopenshell.* plug-in
naming split, Linux's equivalent lives in build_rocky.yml workflow
bash via patchelf + stage_runtime_payload). See src/bonsaiviewer/
CMakeLists.txt for the full version.
## 3. build_osx.yml: drop IFCOS_BUILD_PYTHON_WRAPPER=off
With (1) fixed, the Python wrapper smoke test should pass again. The
gate goes away; the comment block in build_osx.yml is replaced with a
short note pointing at the ifcwrap rpath fix as the underlying change
that re-enables this.
Together, (1)+(2)+(3) close the standalone IfcViewerMinimal-on-macOS
gap (task #43) and re-enable IfcOpenShell-Python on the macOS arm64 CI.
