link error using glaux.lib

i am playing around with opengl. but i am having trouble i try to compile lesson six from nehe. (http://nehe.gamedev.net/data/lessons....asp?lesson=06)
and i get this error:
error LNK2019: unresolved external symbol _auxDIBImageLoadA@4 referenced in function "struct _AUX_RGBImageRec * __cdecl LoadBMP(char *)" (?LoadBMP@@YAPAU_AUX_RGBImageRec@@PAD@Z) lesson6.obj lesson6

anyone able to help?

Looks like you've not used the correct linker switches in the compiler settings. I don't know what they ought to be in your case so you should look on their tutorial. I'll be some DLL or lib or somesuch that is not included in the build.
