Check that installation is correct and emcc is in your path

which emcc should show the path where its installed /usr/lib/emscripten/emcc in my case

get heavy compiler using pip

pip3 install hvcc

In the folder of your patch patch.pd for example run:

hvcc patch.pd -n sine_test -o sine_test -g js

where :
-n its the name
-o its the output name for the folder
-g its the export target

refer to the docs for knowing more

use your favourite http server to serve the files go to the js folder

cd sine_test
cd js
python3 -m http.server

navigate to localhost:8000 on your browser and there you go

follow the instructions given by emscripten to add emsdk PATH permanently to your system
