Hi all, i have a problem, i made some sort of base code for myself and when i try to compile thats what happens. but i have no idea whats going on because my global structure is declared, the header file is included. Also i cant remember what i changed but some time it worked but then the window would go full screen and after like 2-3 secondes would close and i''ll be back to desktop and nothing happened what the hell is that? it happened to me twice. help please InitTerm.obj : error LNK2001: unresolved external symbol "struct __unnamed Global" (?Global@@3U__unnamed@@A) MainGame.obj : error LNK2001: unresolved external symbol "struct __unnamed Global" (?Global@@3U__unnamed@@A) WinLoop.obj : error LNK2001: unresolved external symbol "struct __unnamed Global" (?Global@@3U__unnamed@@A) Debug/basecodeLe0.exe : fatal error LNK1120: 1 unresolved externals
