Hi, I'm trying to get the basics of creating a GL context working by using
GLFW to setup windows etc.
However, when I run the code generated by emcc (1.30.0), I get the
following exception errors:
"exception thrown: ReferenceError: GL is not

I've attached the file I'm trying to build with this post.
I'd be really grateful if anyone could take a look and let me know if I've
done anything wrong?
Cheers!
