Small problem

i know this might be a stupid little small problem but i can't find any way to fix it.

here is my source http://www.fullblowndesigns.com/source.rar

Code: Select all

------ Build started: Project: ICE_Demo, Configuration: Debug Win32 ------

Linking...
ICE_DemoEngine.obj : error LNK2005: "class NPC NPC2" (?NPC2@@3VNPC@@A) already defined in gs_DemoFakeGame.obj
main.obj : error LNK2005: "class NPC NPC2" (?NPC2@@3VNPC@@A) already defined in gs_DemoFakeGame.obj
gs_DemoFakeGame.obj : error LNK2019: unresolved external symbol "public: __thiscall NPC::NPC(void)" (??0NPC@@QAE@XZ) referenced in function _$E1
ICE_DemoEngine.obj : error LNK2001: unresolved external symbol "public: __thiscall NPC::NPC(void)" (??0NPC@@QAE@XZ)
main.obj : error LNK2001: unresolved external symbol "public: __thiscall NPC::NPC(void)" (??0NPC@@QAE@XZ)
../../bin/ICE_Demo.exe : fatal error LNK1120: 1 unresolved externals

any idea whats the problem here?
oh yeah, i stripped out the dependencies and data files to make the source download lighter, in all the download would have been 33.1MB not it's only 1.8MB

What compiler are you using?

He's using Visual Studio. As to what version, I'd say .NET.

Wild shot in the dark - do you have two include files with exactly the same #ifndef?

For example:

#ifndef __SOURCE_FILE_H
#define __SOURCE_FILE_H

#endif

And do you have these in every header file you have created?
