Generating a Mesh from TopoDS_Shape

void COpenCascadeDoc::VisualizeShape(TopoDS_Shape shape,int mode){

BRepMesh::Mesh(shape,0.1);
myAISContext->EraseAll(true);
TopoDS_Compound compound;
BRep_Builder aBuilder;
aBuilder.MakeCompound(compound);
aBuilder.Add(compound,shape);

myAISShape=new AIS_Shape(compound);
myAISContext->SetDisplayMode(myAISShape,mode,Standard_False);
myAISContext->Display(myAISShape,Standard_False);
//myAISContext->UpdateViewer(true);

CMDIFrameWnd *pFrame = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *pChild = (CMDIChildWnd *) pFrame->GetActiveFrame();
COpenCascadeView *pView=(COpenCascadeView*) pChild->GetActiveView();
myAISContext->UpdateCurrentViewer();

if (pView)
{
// pView->myView->MustBeResized();
pView->myView->FitAll();
pView->myView->ZFitAll();
pView->UpdateWindow();
}
//myViewer->UpdateViewer(true);

}

I get a link error saying that,
