[IGSTK-Users] Unresolved external symbol error (Please help)

[Arefin Shamsil]

Hi, 

So far my program was working okay. I think I made some changes and although there isn't any syntax errors, I keep getting a lot of errors like this:

 Error    1    error LNK2001: unresolved external symbol "public: virtual void __thiscall TrackerDataLogger::StartTracking(void)" (?StartTracking at TrackerDataLogger@@UAEXXZ)    C:\Documents and Settings\SArefin\Desktop\IGSTK Build 2\Examples\TrackerDataLogger\igstkTrackerDataLogger.obj
Error    2    error LNK2001: unresolved external symbol "public: virtual void __thiscall TrackerDataLogger::StopTracking(void)" (?StopTracking at TrackerDataLogger@@UAEXXZ)    C:\Documents and Settings\SArefin\Desktop\IGSTK Build 2\Examples\TrackerDataLogger\igstkTrackerDataLogger.obj

Error    8    error LNK1120: 7 unresolved externals    C:\Documents and Settings\SArefin\Desktop\IGSTK Build 2\bin\Debug\igstkTrackerDataLoggerGUI.exe    1


Can anyone tell me what is going on. I really have no idea what wrong here.

Sincerely

Arefin
