[vtkusers] unresolved external symbol

[martin larrea]

Ok. Hello everybody.
Im trying to use implement an observer. I implemen a class (vtkCustomCallback), a very simple one...
 
class vtkCustomCallback : public vtkCommand
{
public:
  static vtkTPWCallback *New() 
    { return new vtkTPWCallback; }
  virtual void Execute(vtkObject *caller, unsigned long, void*)
    {
    }
};
 
As you can see, its very simple. The problem is that when i try to build my proyect i get this errors...
 
TestPlanoW.obj : error LNK2001: unresolved external symbol "protected: virtual void __thiscall vtkObjectBase::CollectRevisions(class std::basic_ostream<char,struct std::char_traits<char> > &)" (?CollectRevisions at vtkObjectBase@@MAEXAAV?$basic_ostream

Debug/TestPlanoW.exe : fatal error LNK1120: 4 unresolved externals
 
I search the web and i didn´t find information...
All my vtk proyecto work fines, i link all the vtk*.lib. The same problem happen in visual studio 6 en visual studio .net...
 
any ideas ?
 
Thanxs to all.
Bye.
