I've been trying to build lesson06 and when I do I get the following two errors: Linking... Lesson06.obj : error LNK2019: unresolved external symbol _auxDIBImageLoadA@4 referenced in function "struct _AUX_RGBImageRec * __cdecl LoadBMP(char *)" (?LoadBMP@@YAPAU_AUX_RGBImageRec@@PAD@Z) Debug/textureMapping.exe : fatal error LNK1120: 1 unresolved externals I've added opengl32.lib glU32.lib glut32.lib to the additional dependecies in the linker properties as well, and it still doesn't work. Is there something else I need to do. Thanks Caleb

try also adding glaux.lib to the list

thanks. that fixed it.
