[vtkusers] Help on writing a graphics filter

[Renato N. Elias]

Hi folks,

I'm trying to write a simple graphics filter which takes a DataSet, 
compute something and add a CellData array to the output's DataSet. The 
structure of the filter is quite the same the vtkElevationFilter, so, I 
just copied the .cxx and .h and changed some stuffs.

Here is the my header created from vtkElevationFilter.h: (all files are 
here 
http://www.nacad.ufrj.br/~rnelias/transfer/ColorBoundaryRegionsFilter.zip )

//--------------------------------------------------------------
#ifndef __vtkColorBoundaryRegionsFilter_h
#define __vtkColorBoundaryRegionsFilter_h

#include "vtkDataSetAlgorithm.h"

class VTK_GRAPHICS_EXPORT vtkColorBoundaryRegionsFilter : public 
vtkDataSetAlgorithm
{
public:
  static vtkColorBoundaryRegionsFilter* New();
  vtkTypeRevisionMacro(vtkColorBoundaryRegionsFilter, vtkDataSetAlgorithm);
  void PrintSelf(ostream& os, vtkIndent indent);

protected:
  vtkColorBoundaryRegionsFilter();
  ~vtkColorBoundaryRegionsFilter();

  int RequestData(vtkInformation*,
                  vtkInformationVector**,
                  vtkInformationVector*);

private:
  vtkColorBoundaryRegionsFilter(const vtkColorBoundaryRegionsFilter&);  
// Not implemented.
  void operator=(const vtkColorBoundaryRegionsFilter&);  // Not implemented.
};

#endif
//--------------------------------------------------------------

The filter's algorithm is implemented in the RequestData method. My 
CMakeLists file is as follows:

#---------------------------------------------------------------
PROJECT(ColorBoundaryRegionsFilter)
FIND_PACKAGE(VTK REQUIRED)
INCLUDE(${VTK_USE_FILE})
ADD_LIBRARY(ColorBoundaryRegionsFilter vtkColorBoundaryRegionsFilter.cxx)
ADD_EXECUTABLE(test test.cxx vtkColorBoundaryRegionsFilter.cxx)
#---------------------------------------------------------------

I can have the filter compiled as library, the problem happens when I 
try to link with the following test program (. The linker gives me a 
bunch of error messages

int main() {
vtkColorBoundaryRegionsFilter* br = vtkColorBoundaryRegionsFilter::New();
br-Delete();
}

Any idea?
