Add --without-subdirs flag to wxWidgets configure to prevent building utils/, samples/, and demos/ directories. These contain native applications like wxrc that shouldn't be cross-compiled to WASM. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Build wxWidgets with wxUniversal for WebAssembly
|
|
# This builds the GUI-enabled wxWidgets needed for KiCad
|
|
#
|
|
# Prerequisites:
|
|
# - Emscripten SDK installed and activated
|
|
# - autoconf (for regenerating configure from configure.in)
|
|
#
|
|
# To regenerate Makefile.in from bakefiles (after modifying files.bkl):
|
|
# cd wxwidgets/build/bakefiles
|
|
# docker run --rm -v "$(pwd)/../..":"$(pwd)/../.." -w "$(pwd)" \
|
|
# ghcr.io/vslavik/bakefile:0.2 bakefile_gen
|
|
#
|
|
# Usage:
|
|
# ./build-wxuniversal-wasm.sh # Clean build (default)
|
|
# ./build-wxuniversal-wasm.sh --no-clean # Incremental build
|
|
|
