Run this to get the make files emconfigure cmake -D CMAKE_C_COMPILER=emcc -D CMAKE_CXX_COMPILER=emcc -D ZLIB_INCLUDE_DIR=$HOME/dev/zlib -D ZLIB_LIBRARY=$HOME/dev/zlib/libz.a .

Then run: emmake make

Then add arguments: ['/hello_world.beam'], to Atom.html after var Module = {

This is such a cool project ;)

This is totally unexpected and cool :)

So please send a PR with a new platform for webassembly! The webassembly platform should contain all the required code and builsystem files needed to run on a browser. It might be interesting to support loading .avm/.beam using a file selector or from a remote http, I think it might be also a good solution for testing purposes :)

If you have any question there is also a slack channel (#atomvm) on elixir lang slack.

emscripten platform has been added.
