Hello, I’m a beginner programmer in Open Gl and I use the Compiler Turbo C++ 3.0. How i use the Open Gl in this compiler?

3.0? That was made in… 1992 I think. That’s too old to compile an OpenGL app. You need a 32-bit compiler (TC++ 3 is 16), like visual c++ or a newer borland compiler.

You can get the free Borland C++ Builder at www.borland.com/bcppbuilder/freecompiler/

You may also get win32-ports of the GCC (well known compiler under LINUX) (and an IDE for that compiler).
Someone else may know the links and post them.
