[vtkusers] undefined reference

[Yenan Qu]

Hi, all,
 
 I have built the vtk5.0.4  without problem. But, when I compile my 
 code with  the new VTK, I got the error below"
 
 /home/yenanqu/VTK-BUILD/lib/libvtkCommonPythonD.so: undefined 
 reference to `vtkDirectory::FileIsDirectory(char const*)'
 /home/yenanqu/VTK-BUILD/lib/libvtkCommonPythonD.so: undefined 
 reference to `vtkObject::RemoveAllObservers()'
 
 I have check vtk source code for both .h and . cxx, the methods 
 vtkDirectory::FileIsDirectory and tkObject::RemoveAllObservers() 
 are well delcared and difined there without differences from 
 others. Does any one know  why  it wasn't just builded in to the lib?
 Thank you in advance.
