Compiling GLUT using Emscripten
I am trying to compile the following code: http://pastebin.com/024Ew4fK
And I am using the following directives: -s LEGACY_GL_EMULATION=1 -lglut -lGLU -lGL
I got the following warnings:
warning: unresolved symbol: glPointSize
warning: unresolved symbol: glutSolidSphere
warning: unresolved symbol: glutWireSphere
And these are the errors:
WARNING: using emscripten GL immediate mode emulation. This is very limited in what it supports
missing function: glPointSize

Why does it say that glPointSize is missing?
Answer
These are the features of Glut supported by Emscripten: https://github.com/kripken/emscripten/blob/master/src/library_glut.js
In order to draw something, for example a sphere, Kripken suggested somewhere to look for a function written in C that does it by itself and then, to port that function to my program.
