env.sh exports a docker-safe JOBS=1 default, and every host build silently
inherited it (the docker kicad path dodges it by passing -j explicitly):
- build-wx-wasm.sh: the intended "${JOBS:-nproc}" fallback sat BELOW the
env.sh source, so it was dead code — full wx builds ran make -j1 on the
Mac and on CI. Compute the all-cores default before env.sh instead
(explicit JOBS/PARALLEL_JOBS still wins); also -j the PCRE pre-build.
- build-wasm-test.sh: same default fix, plus fan the post-link
hoist+asyncify loop out across JOBS with xargs -P. Per-app wasm-opt
can't feed many cores (small modules), so serial stays ~4min even with
BINARYEN_CORES=16; fanning across the 74 independent apps is what
scales. Safe: apply-asyncify is in-place per wasm, injector tmp is
per-js, HOIST_WASMOPT resolved once up front.
- build-gal-webgl-test.sh: make had no -j at all.
Measured on a 16-core M4 Max, clean test-app build: 15m36s (-j1) → 2m08s,
peak RAM 10.7 GB summed across all build processes (64 GB machine; CI
runners have 120 GB). Core counts are always derived from nproc at
runtime — nothing hardcoded, CI workers differ.

# Build script for the WebGL GAL test harness (WASM)
|
|
#
|
|
# This builds a WASM module that renders GAL test scenarios using WebGL,
|
|
# allowing comparison against native OpenGL rendering.
|
|
#
|
|
# Uses a Makefile with direct em++ calls (like build-wasm-test.sh)
|
|
# to avoid emcmake Python 3.10+ requirement.
|
|
#
|
|
# Usage:
|
|
# ./scripts/build-gal-webgl-test.sh # Clean build (default)
|
|
# ./scripts/build-gal-webgl-test.sh --no-clean # Incremental build
|
|
# ./scripts/build-gal-webgl-test.sh --debug # Debug build with source maps
|
|
#
|
|
|
|
# Redirect all output to a log file (re-execs script with redirection)
|
|
