Hi, I have recently tried to make a win32 program and needed to include a library. I use msft vc++ and now after trying to add the lib to my project i get these errors when i compile my program. The default window project even reports these. error LNK2019: unresolved external symbol @_RTC_CheckStackVars@8 referenced in function "long __stdcall WindowProc(struct HWND__ *,unsigned int,unsigned int,long)" (?WindowProc@@YGJPAUHWND__@@IIJ@Z) error LNK2019: unresolved external symbol __RTC_CheckEsp referenced in function "long __stdcall WindowProc(struct HWND__ *,unsigned int,unsigned int,long)" (?WindowProc@@YGJPAUHWND__@@IIJ@Z) error LNK2001: unresolved external symbol __RTC_Shutdown error LNK2001: unresolved external symbol __RTC_InitBase I cant compile anything without these errors coming up. I dont want to mess this up anyworse and i dont know what to do. Please Help! Lambo

Make sure you have the header file for the library #include''d and the library is being linked in, i.e.:

#pragma comment(lib, "your-library-name-here.lib")

or add the .lib to

Project->Settings...->Link tab->Object/library modules box

If you''re using the latter, make sure it''s done for both Release and Debug mode (for VC++ anyway).

I think I hit some settings when trying to add the library and now i cant even link the windows template without these errors coming up. Im not trying to add the library anymore, im just trying to get something to work. I think i messed up the library directories path. Not sure.

Hi,
I fixed it. The library directory settings were out of order. I switched the order that it searched and the problem was fixed. The errors have gone away. it was searching directories that had older versions of the librarys and was not using the newer ones.
