Hi, I''m new to OpenGL programming and I have a question to lesson 6. I''m programming under Borland C++ Builder 6 and don''t know, why it write me an error: "auxDIBImageLoadA not found" or something like that. Do I need some library or what? Where can I find that library? Yes, some code is also for Borland C++ Builder 6 and there is some glaux.lib file, but where can I find it by "official" way? Is there some pack of OpenGL libraries like DirectX or what? Thank you for your answers.

Sure you need a library. That function is in glaux.lib. So you have to link it with that lib. This lib is in NeHe tuts used only for loading BMPs. Use the one, that came with the Builder.
The ''official OpenGL'' includes only OpenGL & GLU so glaux or glut
are separate libs.

Ok, but where can I find 1) ''official OpenGL''
and 2) glaux.lib file - I think there isn''t any in Builder ...
Thank you for your patience ...

''official OpenGL'' means that it is provided with the include files and libs of your C/C++. Because lot of C/C++ have own,
incompatible .lib format. DLLs are in Windows.
opengl32.lib & glu32.lib are in Builder. Also gl.h & glu.h
glaux.lib & glaux.h are in one of the first nehe tutorials i think, but googling glaux.lib+builder may help you.
