[Paraview] problems linking my plugin

[Natalie Happenhofer]

Hi!
Again, I get a linker error building my plugin for paraview, at the point
"Linking CXX shared library ..\bin\libDataCalculator.dll"

it says: 
"In function 'ZNK17vtkDataCalclulator19NewInstanceInternalEv':
.... undefined reference to vtkDataCalculator::FillInputInformation(int,vtkInformation*)"

My code looks like this:
vtkDataCalculator.h:

#ifndef __vtkDataCalculator_h
#define __vtkDataCalculator_h


#include "vtkUnstructuredGridAlgorithm.h"

class VTK_EXPORT vtkDataCalculator: public vtkUnstructuredGridAlgorithm
{ public:
  static vtkDataCalculator *New();

  vtkTypeRevisionMacro(vtkDataCalculator,vtkUnstructuredGridAlgorithm);
  void PrintSelf(ostream& os, vtkIndent indent);

protected:
    vtkDataCalculator();
    ~vtkDataCalculator(){};
    
    virtual int FillInputPortInformation(int port, vtkInformation* info);
    virtual int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *);
};
#endif


vtkDataCalculator.cxx:

#include "vtkDataCalculator.h"
#include "vtkDataSet.h"
#include "vtkDataArray.h"
#include "vtkUnstructuredGrid.h"
#include "vtkObjectFactory.h"
#include "vtkPointData.h"
#include "vtkDoubleArray.h"
#include "vtkAlgorithm.h"
#include <fstream>
#include "vtkSmartPointer.h"
#include "vtkInformation.h"
#include "vtkInformationVector.h"

vtkStandardNewMacro(vtkDataCalculator);
//----------------------------------------------------------------------------
vtkCxxRevisionMacro(vtkDataCalculator,"$Revision$");
//----------------------------------------------------------------------------
vtkDataCalculator::vtkDataCalculator(){} 
                                                                       }
//----------------------------------------------------------------------------
void vtkDataCalculator::PrintSelf(ostream& os, vtkIndent indent)
{
    this->Superclass::PrintSelf(os,indent);
}
//----------------------------------------------------------------------------
int FillInputPortInformation(int ,vtkInformation* info)
{ 
    info -> Set(vtkAlgorithm::INPUT_REQUIRED_DATA_TYPE(),"vtkDataSet");
    info -> Set(vtkAlgorithm::INPUT_IS_REPEATABLE(), 1);
    return 1;
}
//----------------------------------------------------------------------------
int vtkDataCalculator::RequestData(vtkInformation *vtkNotUsed(request),
                                      vtkInformationVector **inputVector,
                                      vtkInformationVector *outputVector)
{...
}


Is there a macro missing or... ?

thx for help,
Natalie
