Build

Fetch Emscripten from DockerHub:

docker pull robertaboukhalil/emsdk:1.38.26

Create a container from that image:

# Create container from that image
docker run -dt --name wasm robertaboukhalil/emsdk:1.38.26

# Enter the container
docker exec -it wasm bash

Within the container, fetch the code:

git clone "https://github.com/robertaboukhalil/wasm-asteroids.git"
cd wasm-asteroids

And compile it to WebAssembly:

emcc \
    -o app.html asteroids/*.c \
    -Wall -g -lm \
    -s USE_SDL=2
