Irrlicht Engine

Sorry, my mistake. Check your makefiles, I think you are not linking libjpeg at all.

What about handling camera? There will be some way to change camera position without reimplementing the whole class?
Also getting a submesh from a model by name and play animation by name for 3ds files? I dont know if md2 files can be used for commercial projects.

I think that the jpeg problems are that you are linking against a lib other than the the used to compile the engine. So, some functions are missing.
