/FORCE

Delete/Move(to diff folder) all the .obj files. Occassionally, the compiler doesn''t rewrite theses, just appends info.

Thanks for the suggestion, but it didn''t work. I will definately try keep that in mind however.
Any other ideas?

Thanks

What the LNK2005 warning means is that a particular function body or variable definition was found in more than one .cpp file. This is usually because you have a function not declared inline, but with its body in a header file, or a variable definition in a header. So, move all your function bodies out of header files, and for any global variables, declare them in the header as, for example,

extern int someInteger;

and then place

int someInteger;

in ONE .cpp file.

tr0n,
Yeh i think i get what its trying to say, but it isn''t making any sense as its picking up EVERY function/variable as already being declared in ALL of the .obj files. And as all my code is in seperate classes (with the exception of the game init, game loop and game shutdown) i dont really think this could be possible.

I will try to explain the structure of the project files:
I have a main header file which includes all of the other class header files. All the .cpp files include this main header file.

I think i know why im getting this error (because of this structure) but my understanding was that if you included the #ifndef _HEADER_FILE_H - #endif compiler directives that it wouldn''t include the headers if they had already been included? Like I said I dont know a lot about how this works so any advice would be appreciated. I realise without posting some code this will be hard to explain and understand but that really isn''t an option. I can paste the error codes (about 600 lines!) if that would help.

ta.

You''re right- it is hard to see what''s wrong without some code to look at.

However, not having the include guards (#ifndef ...) in the headers would (I think) give compiler errors, rather than linker errors.

Post the errors if you can, the might be helpful.

Ok I have had a closer look at the errors and it IS only picking up the global variables (I have no idea why I thought otherwise). I tried putting extern infront of the globals and that got rid over over half the errors but introduced LNK2001 errors, so I think I need to read up on the extern keyword and see if I can figure out what I need to do. Thanks for the advice before tr0n, im guessing you were right

BTW the errors i was getting before were:
CKeyboard.obj : error LNK2005: "int g_Score" (?g_Score@@3HA) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "int g_Lives" (?g_Lives@@3HA) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "int g_CurrLevel" (?g_CurrLevel@@3HA) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "float lasttime" (?lasttime@@3MA) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "float currtime" (?currtime@@3MA) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "float g_timerdiff" (?g_timerdiff@@3MA) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "__int64 g_Frequency" (?g_Frequency@@3_JA) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "struct IDirectInput8A * g_pDI" (?g_pDI@@3PAUIDirectInput8A@@A) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "struct IDirect3DDevice8 * g_pD3DDevice" (?g_pD3DDevice@@3PAUIDirect3DDevice8@@A) already defined in CCamera.obj
CKeyboard.obj : error LNK2005: "struct IDirect3D8 * g_pD3D" (?g_pD3D@@3PAUIDirect3D8@@A) already defined in CCamera.obj

and it seemed to repeat for each of the header files i have. So the next lot would be:
CMesh.obj : error LNK2005: "int g_Score" (?g_Score@@3HA) already defined in CCamera.obj
etc...

If (when) I get stuck i will let you know.

thanks again,

add StdAfx.h, it should include all the headers. The headers should include everything they need, and NOT StdAfx.h. THe codefiles should include StdAfx.h ONLY.

StdAfx.h -> All
Header -> All (except StdAfx.h)
Cpp -> StdAfx.h

If you get into header <-include-> header problem,
do this:

// ClassA.h
class CClassB;
#include "CClassB.h"
...

.lick

Pipo,
Thats the reason actually why i started re-arranging all of my files in the first place because 2 headers needed each other so thanks for the tip. Ah well the code was getting really messy so its a good thing i did it anyway.

I FIXED IT!!!!

Just wanna says thanks to all the advice that everyone gave. I have been working on the for around 14 hours now and has easily been my biggest coding problem i''ve had. Bit of advice to everyone - plan out your code from the start!!!

Thanks people,
