I am getting these strange linker errors: FreakoutVSdotNET2003_1 error LNK2001: unresolved external symbol @_RTC_CheckStackVars@8 FreakoutVSdotNET2003_1 error LNK2001: unresolved external symbol __RTC_CheckEsp FreakoutVSdotNET2003_1 error LNK2001: unresolved external symbol __RTC_InitBase FreakoutVSdotNET2003_1 error LNK2001: unresolved external symbol __RTC_InitBase FreakoutVSdotNET2003_1 error LNK2001: unresolved external symbol __RTC_Shutdown FreakoutVSdotNET2003_1 error LNK2001: unresolved external symbol __RTC_Shutdown FreakoutVSdotNET2003_1 error LNK2019: unresolved external symbol @_RTC_CheckStackVars@8 referenced in function "int __cdecl DD_Init(int,int,int)" (?DD_Init@@YAHHHH@Z) FreakoutVSdotNET2003_1 error LNK2019: unresolved external symbol __RTC_CheckEsp referenced in function "int __cdecl DD_Init(int,int,int)" (?DD_Init@@YAHHHH@Z) FreakoutVSdotNET2003_1 fatal error LNK1120: 4 unresolved externals Can anyone help me? Have I forgot to include a lib or something like that? I am trying to compile the Freakout example from "Tricks of the Windows game programming gurus" with VS.NET 2003. The code is in C/C++.

You forgot to link with either a lib or some other translation unit(s). Unfortunatly, I don't know TWGPG enough to be able to exactly tell you what is missing. Where do these RTC_* function come from?

The missing symbols are part of the RunTime Check system which are called depending on certain compiler settings.

Go to Projects->Properties->C/C++->Code Generation and check the settings in there - particularly the 'Basic Runtime Checks' and the 'Runtime Library' settings. You may have a nonsensical combination in there which is causing these problems. It may also be that your library path is pointing at an out of date C Runtime Library - check the library paths under tools->options->Projects->VC++ Directories->Library files, and make sure you've got the most recent files at the top of the list.

Thanks, sandman, that worked. Got it compiled and runnin'. It was just really strange beacause it compiled ok with vc++ 6.0 straight out.

With that code, we can run on Studio.net ?

I had a source called by decklinkframesource. This code communicate with DeckLink card (Graphic card).

I can't compile it on Studio.net . I got some errors the same as

CustomAllocator.obj : error LNK2019: unresolved external symbol __RTC_CheckEsp referenced in function "public: static class CUnknown * __stdcall CCustomAllocator::CreateInstance(struct IUnknown *,long *)" (?CreateInstance@CCustomAllocator@@SGPAVCUnknown@@PAUIUnknown@@PAJ@Z)
