Hello,
I am a EE masters student and I am trying to use MPEG 4 Systems reference software (version 2) for my masters project. When I try to compile the Im1-2D in microsoft visual C++ 6.0( on windows XP), I am getting 6 compilation errors (actually Linking errors). 
I had an earlier version of the systems software (version 1). Initially I got errors in it too, but I could resolve it and  could compile and use the IM1core. However I am having a hard time resolving the errors of Version 2 Im1-2D. The errors that are displayed are:
Linking...
Clock.obj : error LNK2001: unresolved external symbol "public: bool __thiscall MediaControlImp::IsUnitPlayable(double)" (?IsUnitPlayable MediaControlImp@@QAE_NN Z)
DataChan.obj : error LNK2001: unresolved external symbol "public: void __thiscall MediaControlImp::Play(int)" (?Play MediaControlImp@@QAEXH Z)
OpenStr.obj : error LNK2001: unresolved external symbol "public: void __thiscall MediaControlImp::Play(int)" (?Play MediaControlImp@@QAEXH Z)
Executiv.obj : error LNK2001: unresolved external symbol "public: __thiscall MediaControlImp::MediaControlImp(void)" (??0MediaControlImp@@QAE XZ)
OpenStr.obj : error LNK2001: unresolved external symbol "public: void __thiscall MediaControlImp::StreamStopped(void)" (?StreamStopped MediaControlImp@@QAEXXZ)
..\Debug\IM1-2D.exe : fatal error LNK1120: 4 unresolved externals
Error executing link.exe.
IM1-2D.exe - 6 error(s), 20 warning(s)
Can anyone please tell me how to go about it or what should I do differently? Any project settings to be changed etc.
I appreciate any guidance and help regarding the matter.
Thanks 
Swetha
