Linker Error: Undefined reference

Question

I'm using the source code in this article.

I've simply copy and pasted the source to my own project, and Dev-C++ is finding all of the includes; however, when I compile I receive a slew of "linker errors" such as the following:

[Linker error] undefined reference to _imp__ilGenImages@8

Have I set up my environment improperly somehow? How do I fix it?

Yep, I think genpfault is right. Use Code::Blocks if you want a free, quite light, portable solution. — Raveline, Nov 21 '10 at 12:20

Have you linked your application against the lib-files included with Devil?

You probably forgot to link against the static libraries. Read the manual of your compiler to find out how to do that in your case.

I've added DevIL, ILU, and ILUT.lib to my Linker and I still seem to be getting the same errors. Odd... – Jamie Nov 17 '10 at 18:45

Dev-Cpp uses GNU compiler. It could not understand .lib files. If you still wanna use DevIL, you should build it from sources (avaliable from their site ; needs some dependices too), use Visual Studio (which is more painless way) or use another library (SDL_image, SFML would be good enough).
