NaviPane Application on CodeWarrior

Hi all,

I'm Using Codewarrior as my IDE.  I'm developing a naviPane Application.

Upon Compilation, i get the following errors:

Link Error: Undefined Symbol: 'class CCoeControl * CEikStatusPaneBase::ControlL(class TUid) const ?ControlL@CEikStatusPaneBase@@QBEPAVCCoeControl@@VTUid@@@Z)'

This is my code for the application:

void CmyowntickerAppUi::ConstructL()
    {
   
    BaseConstructL();

    iAppView = CmyowntickerAppView::NewL(ClientRect());   
    CEikStatusPane * sp=iEikonEnv->AppUiFactory()->StatusPane();
    CAknNavigationControlContainer * np=(CAknNavigationControlContainer*)sp->ControlL(TUid::Uid(EEikStatusPaneUidNavi));
   
    if(iNaviDecorator)
       iNaviDecorator=NULL;
    iNaviDecorator=np->CreateMessageLabelL(_L("Last Measurement!"));
    np->PushL(*iNaviDecorator);

    AddToStackL(iAppView);
    }
Someone please help me out on this!!! I'm pretty new to both Symbian and CodeWarrior!!!

Thanx...
Ashwin...
