Build hello_world.c
using
emcc hello_world.c -Os -s WASM=1 -s SIDE_MODULE=1 -o hello_world.wasm
(make sure to use latest Emscripten incoming). That creates a
WebAssembly dynamic libraryhello_world.wasm
. You can then run
hello_world.html
in your browser, which loads and uses it.

@iiic The old fastcomp backend added
_
prefixes on the wasm exports. The new upstream backend (like in the version you use) doesn't, which can be noticeable if you access the exports directly.
