The wxWidgets autoconf build inside Docker failed with `emmake: command not
found` on a clean build, while the KiCad CMake build survived (CMake caches the
absolute compiler path). Two compounding causes:
1. `docker compose exec` bypasses the ENTRYPOINT, so it never sourced
emsdk_env.sh and EMSDK was unset. env.sh then fell back to the local
tools/emsdk.
2. The entrypoint's rsync from the host bind mount excluded only build-wasm and
output, so the host's macOS-arm64 tools/emsdk got copied over the container's
Linux emsdk. The macOS Mach-O python can't exec on Linux, so
`emsdk construct_env` failed ("Exec format error") and emcc/emmake never
landed on PATH.
Fixes:
- Set `ENV EMSDK=/emsdk` in the image so every process (including
`docker compose exec`) resolves env.sh's EMSDK branch to the container's own
emsdk and never falls back to tools/emsdk.
- Exclude `tools/emsdk` from the entrypoint rsync so the host emsdk can no
longer leak into the container.
Validated with a clean wxWidgets build (`build-wxuniversal-wasm.sh --clean`):
reconfigures and compiles all 42 wx libs against /emsdk with no missing-tool
errors.
