[Dev-C++] Undefined Reference?

[Scott <fre...@ve...>]

Hi, 

I'm getting 18 errors like the following with DevC++

I use DevC/C++ without problem usually, but i get
these errors, as part of a 3D SDK....

Is it a Opensource OGL library issue, can it be fixed?

  [Linker error] undefined reference to `glClearColor@16' 
  [Linker error] undefined reference to `glClear@4' 
  [Linker error] undefined reference to `glColor3f@12' 

Cheers,
Scott.
