Hi,

I'm trying to build box2d.js (to use ALLOW_MEMORY_GROWTH) on Linux. However, the build process stops because of this error :

Does webidl stuff work in general on that machine? try ./tests/runner.py test_webidl in emscripten root. No idea how that could fail, but maybe reinstalling the latest sdk might help?
