# Makefile to use with GLFW+emscripten
|
|
# See https://emscripten.org/docs/getting_started/downloads.html
|
|
# for installation instructions.

#
|
|
# This Makefile assumes you have loaded emscripten's environment.
|
|
# (On Windows, you may need to execute emsdk_env.bat or encmdprompt.bat ahead)
|
|
#
|
|
# Running `make` will produce three files:
|
|
# - web/index.html
|
|
# - web/index.js
|
|
# - web/index.wasm
|
|
#
|
|
# All three are needed to run the demo.
