How to Build

How to Run

To run on a local machine:

  • make serve will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
  • Otherwise, generally you will need a local webserver:
    • Quoting https://emscripten.org/docs/getting_started:
      “Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// XHR requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a local webserver and then open http://localhost:8000/hello.html.”
    • Emscripten SDK has a handy emrun command: emrun web/example_emscripten_opengl3.html --browser firefox which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
    • You may use Python 3 builtin webserver: python -m http.server -d web (this is what make serve uses).
    • You may use Python 2 builtin webserver: cd web && python -m SimpleHTTPServer.

Obsolete features:

  • Emscripten 2.0 (August 2020) obsoleted the fastcomp backend, only llvm is supported.
  • Emscripten 1.39.0 (October 2019) obsoleted the BINARYEN_TRAP_MODE=clamp compilation flag which was required with version older than 1.39.0 to avoid rendering artefacts. See #2877 for details. If you use an older version, uncomment this line in the Makefile: #EMS += -s BINARYEN_TRAP_MODE=clamp
