[vtkusers] need help in using vtkPolyDataReader

[Dan Lee]

Dear vtk users,
 
   I'm new in using vtk. When I tried to use vtkPolyDataReader to input .vtk format data in an exercise, I run into trouble and  got following compiling problem: 
 
--------------------Configuration: StrSph2 - Win32 Debug--------------------
Linking...
StrSph2.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: class vtkPolyData * __thiscall vtkPolyDataReader::GetOutput(void)" (__imp_?GetOutput at vtkPolyDataReader@@QAEPAVvtkPolyData@@XZ)
StrSph2.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: static class vtkPolyDataReader * __cdecl vtkPolyDataReader::New(void)" (__imp_?New at vtkPolyDataReader@@SAPAV1 at XZ)
Debug/StrSph2.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.
ALL_BUILD - 3 error(s), 0 warning(s)

 
My code is following. Any help is highly appreciated.
 
Thanks.
