Open GL issues

Hi all I'm getting ready to spend some time doing open GL in Between semesters. Anyways, I was just trying to compile this stuff and I get an unresolved external error message. and quote

error LNK2001: unresolved external symbol _gluPerspective@32

whats the deal with this I can't figure out what the issue is here. I've tried adding the gl library and nada. So I tried cutting the source out of the original header files and just adding the code to a set of generic header files still nothin sooooooo whaddya say any input here

That looks like it's trying to link with the glu library (which is a utility library on top of opengl) since you haven't said what you are using I can't help much more but I know that under linux glu and opengl are 2 different libraries and you must link against both.
