I keep getting these stupid errors every time I compile: player.obj : error LNK2005: "struct sTile (* map)[5]" (?map@@3PAY04UsTile@@A) already defined in class_func.obj functions.obj : error LNK2005: "struct sTile (* map)[5]" (?map@@3PAY04UsTile@@A) already defined in class_func.obj game.obj : error LNK2005: "struct sTile (* map)[5]" (?map@@3PAY04UsTile@@A) already defined in class_func.obj Game___Win32_Debug/Game.exe : fatal error LNK1169: one or more multiply defined symbols found Error executing link.exe. I do multiple includes in class_func.cpp, player.cpp, and etc., and I made sure to use

#ifndef PLAYER
#define PLAYER

//code goes here

#endif
 

but I still get these dumb errors!

You are defining ''map'' in the header. Every source-file/module that includes this header will therefore get it''s own definition of map, and these multiple definitions will clash at link-time. The solution is to declare ''map'' extern in the header, and define it in exactly one source-file.

I have found that I get this error if I do certain defines before includes like:

#define INITGUID
#define WIN32_LEAN_AND_MEAN
#include
#include

INSTEAD OF

#include
#include
#define INITGUID
#define WIN32_LEAN_AND_MEAN

once again, I''m not an expert so I am just saying ONE thing that has caused these kind of errors for me.

ahhh okay thanks

Those defines alter the behavior of the includes, so if you''re getting errors by placing them before the headers, you''re doing something wrong.

#define INITGUID, for example, should come before virtually all includes; #define WIN32_LEAN_AND_MEAN causes the inclusion of windows.h to exclude rarely used stuff - declaring it after the include is redundant.


I wanna work for Microsoft!

I hate to post this whole code segment, but any idea what I am doing wrong here? When I put the defines before the includes I get the same type of errors that Kaezin is getting. However, if I put the defines after the includes, it compiles just fine:

      #ifndef __ENGINE_H__#define __ENGINE_H__// standard includes#include	<d3d8.h>#include	<d3dx8.h>#include	<stdio.h>// standard defines#define		INITGUID#define		WIN32_LEAN_AND_MEANclass CEngine {	public:				// ******* VARIABLES ******* //				// window handles		HINSTANCE					m_hInstance;		HWND						m_hWnd;		// ******* FUNCTIONS ******* //				int		iInit3D( void );		void	vRenderScene( void );		// Constructor and Destructor		CEngine( );		~CEngine( );	private:		// ******* VARIABLES ******* //				// direct3d globals		LPDIRECT3D8					m_pD3D;		LPDIRECT3DDEVICE8			m_pD3DDevice;		D3DXMATRIX					m_matProj;					// projection data		D3DXMATRIX					m_matCameraView;				// camera data		D3DXVECTOR3					m_vecCameraSource;		D3DXVECTOR3					m_vecCameraTarget;		LPDIRECT3DVERTEXBUFFER8		m_lpVertexBuffer;		// definition for our vertex shader		#define		D3DFVF_MYVERTEX (D3DFVF_XYZ | D3DFVF_TEX1)		// vertex structure		typedef struct MYVERTEX {			float	x;			float	y;			float	z;			float	u;			float	v;		} MYVERTEX, *LPMYVERTEX;		// global vertices		MYVERTEX m_Vertices[4];		// ******* FUNCTIONS ******* //				void	vSetupView( void );};#endif       

Yikes!!! This really expands the tabs. Sorry about the code being so wide.
