Can't compile a DLL. Need someone that knows how to do it for me.

I can't compile this into a DLL. I can't get any of the correct header files into it before I get utterly frustrated and quit (I don't know much C++).

It's supposed a module for Garry's Mod, a HL2/Source mod.

So can somebody please get all the proper header files it includes and compile this source into a .DLL for my personal use? I really need this.

Please name it gmcl_se2.dll

Here are the HL2SDK headers and some of the GMod headers (some of them are needed I think)

You have lots of reading to do on what this code will need..you'll probably want to read all the docs relating to the HL2/GMod before trying to compile this..

Project includes that aren't part of a widely used SDK, such as the standard library or say Win32-SDK, are basically usage specific and we wouldn't know by inspection which ones you'd need.
