[charfeddine amir]

Hi all
 i get the following error while trying to change my actor color to RED :
 
 /home/work/AppBase.cxx:4186:error: invalid use of undefined type 'struct vtkProperty'
 /usr/local/include/vtk/vtkActor.h:39: error: forward declaration of 'struct vtkProperty'
 
 and this is my code :
 
   vtkActor* actor = vtkActor::New();
   renR->AddActor(actor);
 
   vtkDataSetMapper* mapper = vtkDataSetMapper::New();
   mapper->SetInput(MeshToUnstructuredGrid( meshSource->GetOutput() ) );
 
   actor->SetMapper(mapper);
   actor->GetProperty()->SetColor( 1, 0, 0 );
