# Makefile to use with emscripten
|
|
# See https://emscripten.org/docs/getting_started/downloads.html
|
|
# for installation instructions. This Makefile assumes you have
|
|
# loaded emscripten's environment.
|
|
#
|
|
# Running `make` will produce three files:
|
|
# - example_emscripten.html
|
|
# - example_emscripten.js
|
|
# - example_emscripten.wasm
|
|
#
|
|
# All three are needed to run the demo.
