src/binaryen/build-js.sh

   1 #
   2 # This file builds the js components using emscripten. You normally don't need
   3 # to run this, as the builds are bundled in the repo in bin/. Running this is
   4 # useful if you are a developer and want to update those builds.
   5 #
   6 # Usage: build-js.sh
   7 # Usage: EMSCRIPTEN=path/to/emscripten build-js.sh  # explicit emscripten dir
   8 #
   9 # Emscripten's em++ and tools/webidl_binder.py will be accessed through the
  10 # env var EMSCRIPTEN, e.g. ${EMSCRIPTEN}/em++
  11 #
  12 # You can get emscripten from
  13 # http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
