Linux(Ubuntu 14.04) setting up OpenGL

1. Install c/c++ compilation package.

2. install openGL and freeGlut library

sudo apt-get install mesa-common-dev

sudo apt-get install freeglut3-dev

3. testing: run this code (comes from openGL red book) by save it as a cpp file. Then open the terminal and navigate to the directory containing this cpp file.

g++ text.cpp -lglut -lGL
Then you will get an a.out. run it by

./a.out4. Done

 1 #include "GL/freeglut.h"
 2 #include "GL/gl.h"

19     glEnd();
20     glFlush();

24 the freeglut library does the window creation work for us,
25 regardless of the platform. */
