(Ubuntu)安裝OpenGL/Glut庫

sudo apt-get install freeglut3 freeglut3-dev

如果Ubuntu的版本在11.10或者更高的話還需要安裝下面的包以解決連接配接問題 // For newer versions of Ubuntu(>=11.10) you have to install another package because the linker does not link anymore. 

sudo apt-get install binutils-gold

1. 編輯 color_cube.cpp

2. 通過連結OpenGL/Glut庫來編譯 color_cube.cpp       

g++ -lGL -lglut color_cube.cpp -o test

3. 運作結果如下
