I've been trying to compile this example for PNG texture mapping in OpenGL that I found here: http://www.wyatt100.freeserve.co.uk/ I'm not even sure what system it was compiled for, but I figured I'd try out the library. I'm having an unusual linker error though, as you will see...because it does not appear to be related to the library, instead it seems to relate to GLUT. Well, here is the information you need:

Try changing the link order to:
-lglut32 -lglu32 -lopengl32
or use grouping:
-( -lglut32 -lglu32 -lopengl32 -)
Link order is significant since by default the linker only makes one pass at each library in the order listed on the command line. A symbol cannot be introduced in a library that is not resolved in the same library or a later one. The linker only carries forward unresolved symbols, not symbols that may or may not be needed by subsequent libraries.
The grouping solution using -( <library list> -) causes the linker to iterate the group until no further symbols are resolved - it is necessary for libraries with circular dependencies and is otherwise a quick-and-dirty way of not having to figure out the order of dependency. It increases build time which may or may not be significant depending on the size of the project and the order you list the libraries.
Other than that, you obviously took a look at the "Read First" thread, but failed to observe teh advice about paths containing spaces: "C:\Documents and Settings\Megan Bednarz\My Documents" is not an advisable location for your project.

So, there are the mandatory 3 bits of info. I thought I followed all directions properly, but I am probably missing something very obvious...
Oh, so the strange part is: these seem to be errors related to GLUT, even though I've been actually using GLUT successfully for other programs I have run. I don't quite remember where I got the GLUT library... probably from opengl.org, so that could be one of the problems. I also might not be linking the png texture mapping header file right, or it could be made wrong and I might have to recompile the source code (oh I don't even want to think about that...at least it comes with source code, though).
