Stupid link errors!!!
Author
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
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.
#define INITGUID
#define WIN32_LEAN_AND_MEAN

I have found that I get this error if I do certain defines before includes [remove examples]
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:
Yikes!!! This really expands the tabs. Sorry about the code being so wide.
