mkdir hello
cd hello
echo '#include <stdio.h>' > hello.c
echo 'int main(int argc, char ** argv) {' >> hello.c
echo 'printf("Hello, world!\n");' >> hello.c
echo '}' >> hello.c
emcc hello.c -s WASM=1 -o hello.html

printf '#include<iostream> \nint main() { std::cout<<"hello world"<<std::endl; return 0;}' > helloworld.cpp

docker run --rm -v $(pwd):/src trzeci/emscripten emcc helloworld.cpp -o helloworld.html

docker run --rm -v $(pwd):/src trzeci/emscripten emcc math.c -Os -s WASM=1 -s SIDE_MODULE=1 -o math.wasm
