## How to Build
|
||||
|
||||
- You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions

## How to Run
|
||||
|
||||
To run on a local machine:
|
||||
- Generally you may need a local webserver. Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
|
||||
- `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](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
|
||||
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-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](https://emscripten.org/docs/getting_started/FAQ.html#faq-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.
|
||||
- Otherwise you may use Python builtin webserver: `python -m http.server -d web` in Python 3 (or run shortcut `make serve`) or `cd web && python -m SimpleHTTPServer` in Python 2. After doing that, you can visit http://localhost:8000/.
