Hi,
Im using Dev C++. And am having trouble getting OpenGL to display in a FLTK Window. Im totally new to both c++ in general. However can code in C & Java (so understand most commands & OO).
I have followed the tutorial located (
www.gidforums.com ) to get a Hello World Program to display in FLTK. That part works fine. I have also installed the OpenGLUT Package in Dev C++, and this displays A rotating triangle fine.
However, when i try to use the following code (
seriss.com ) to test a simple OpenGL + FLTK example. I get errors.
I think its because Im not using both the OpenGL & FLTK Packages at the same time. Could some one please tell me how to get rid of the following errors.
