The tutorial on using the engine dll, acknex.dll, doesn't give the same kind of step by step instructions as the tutorial on creating your own DLLs that are used by the engine. And I'm stuck trying to make this work. I create a Win32 project (and link acknex.lib and do the other library stuff specified in the tutorial, I also copy the engine files to my project directory), I replace the default script it provides with the one in the tutorial and try to compile. First it complains that I haven't included "stdafx.h", so I do that. Then when I compile it acts like it doesn't know what a UINT is! And then a bunch of errors related the ENGINE_ type. I must be doing something really basic wrong.
