Hi all
I am trying to put together the code for the CrystalSpace3d Game engine.
But when i build my solution, when i have both of the files specified in the title. It still comes up with this error:

fatal error C1083: Cannot open include file: 'csutil/csosdefs': No such file or directory
I have never encounted this error before and have no idea what to do.

Can anyone help me?

BTW, I'm not sure what board this should be on, so complain if you have to.
