Where to start?

Hi! I have been learning C++ for about half a year and now I would like to learn OpenGL. Can you give me some good tutorials/books on OpenGl?

Thank you!
But I have another problem. I downloaded freeglut 2.8.1 but when I open a new GLUT project in Code::Blocks and browse the OpenGL folder it says:“The wizard can’t locate the include directory”, though there is a include directory.

There’s no need for some fancy wizard magic tool. In your IDE, just set add the freeglut include directory to the include path (you probably also want glew) and add the necessary libraries for linking (freeglut and glew).
