Gergő Törcsvári d6d743340d refactor(build): fold calculator into unified docker/build.sh dispatch Convert the calculator port (commit `0464470`) from the parallel/copy-paste pattern to the dispatch pattern used by pcbnew + eeschema. - docker/build.sh: <app> is now required (no pcbnew default); missing, unknown, and --help paths all print "pcbnew \| eeschema \| calculator \| all". Adds calculator to build_app() via kicad_subdir_for() (pcb_calculator inner subdir, calculator.* output basename). Also fixes the EMSDK=/emsdkkicad-wasm-builder typo that snuck in during the calc merge. - scripts/kicad/build-kicad-target.sh: accepts calculator; introduces KICAD_TARGET (pcb_calculator for calc, == APP_NAME otherwise) used for the make target, embind include path, and final-log line. - scripts/kicad/build-calculator.sh: 305-line copy of build-pcbnew.sh collapsed to a 7-line wrapper around build-kicad-target.sh. - tests/scripts/setup-kicad-wasm.sh: copy_app calculator added with the same pcb_calculator subdir mapping for the docker-volume fallback path. - tests/package.json: test:calculator* routed through the shared playwright-kicad.config.ts kicad/calculator.spec.ts (mirrors eeschema). - Delete: docker/build-calculator.sh, tests/scripts/setup-calculator-wasm.sh, tests/playwright-calculator.config.ts. Bumps wxwidgets d1d1627 -> 6fb2eac (origin/wasm-port). The new sha includes "unic/combobox: add GetCurrentSelection() inline default" which calc's kicad/pcb_calculator/widgets/unit_selector.cpp needs to compile. Without this bump the unified dispatch would expose calc as a buildable target but the build itself would fail. Verified: build.sh all completes clean across all three apps; pcbnew/eeschema e2e pass; calc compiles and launches (test stability separate from this refactor).

Docker Build Environment for KiCad WASM

This directory contains Docker configuration for building KiCad for WebAssembly in a reproducible, isolated environment.

Prerequisites

Docker Desktop (with Docker Compose v2)
Git submodules initialized: git submodule update --init --recursive

Quick Start

# Build KiCad WASM (full build)
./docker/build.sh

# Build with options
./docker/build.sh --no-clean    # Skip cleaning build directory
./docker/build.sh --debug       # Build with debug symbols

# Interactive shell for debugging
./docker/shell.sh

Branch-Specific Builds

Each git branch gets isolated Docker containers and volumes, enabling parallel development:

# On branch 'main' → containers/volumes prefixed with 'kicad-wasm-main'
# On branch 'feature-x' → containers/volumes prefixed with 'kicad-wasm-feature-x'

This allows you to:

Work on multiple branches simultaneously using git worktrees
Each worktree has its own build cache (no conflicts)
Switch branches without rebuilding from scratch

Using git worktrees for parallel development:

# Create a worktree for a new branch
git worktree add ../kicad-wasm-feature path/to/branch

# Build in the worktree (uses isolated Docker volumes)
cd ../kicad-wasm-feature
./docker/build.sh

# List all worktrees
git worktree list

What Gets Built

The build process includes:

Dependencies (cached in Docker volume):
- GLM (header-only)
- Zstd, Protobuf
- FreeType, HarfBuzz
- Pixman, Cairo
- Boost (Locale)
- OpenCASCADE (optional, for 3D/STEP)
- CURL headers, libgit2 headers (stubs)
wxWidgets (built from submodule)
KiCad PCBnew (main application)

Container Resources

Configured for M4 Max (adjust in docker-compose.yml):

CPUs: 10 cores
Memory: 16GB

Volume Strategy

Path	Type	Purpose
`/workspace`	Bind mount	Source code
`/workspace/build-wasm`	Named volume	Build cache (deps, sysroot)
`/workspace/output`	Bind mount	Final WASM output

Common Commands

# Start container
docker compose -f docker/docker-compose.yml up -d

# Run a command inside
docker compose -f docker/docker-compose.yml exec kicad-wasm-builder <command>

# View logs
docker compose -f docker/docker-compose.yml logs -f

# Stop container
docker compose -f docker/docker-compose.yml down

# Clear build cache (full rebuild)
docker volume rm docker_kicad-build-cache

Troubleshooting

Build freezes

The OpenCASCADE build is very resource-intensive. If it freezes:

Reduce parallel jobs: Edit script to use -j4 instead of -j$(nproc)
Monitor with docker stats
Consider building OpenCASCADE separately with ./scripts/deps/build-opencascade.sh

Permission issues

Files created in container are owned by root. To fix:

sudo chown -R $(whoami) output/

Cache issues

# Clear all cached builds
docker volume rm docker_kicad-build-cache

# Or clear specific stamps inside container
./docker/shell.sh
rm /workspace/build-wasm/stamps/*.stamp
