Make sure your header and cxx files look something like follows:
vtkDataCalulator.h -----
#include "vtkDataSetAlgorithm.h"
class VTK_EXPORT vtkDataCalculator : public vtkDataSetAlgorithm
{
public:
static vtkDataCalculator* New();
vtkTypeRevisionMacro(vtkDataCalculator, vtkDataSetAlgorithm);
...
};
------------------------------------
vtkDataCalculator.cxx-----------------
#include "vtkDataCalculator.h"
#include "vtkObjectFactory.h"
vtkStandardNewMacro(vtkDataCalculator);
vtkCxxRevisionMacro(vtkDataCalculator, "$Revision$");
....
------------------------------------

Hi!
I´m writing a new filter called vtkDataCalculator, which should
add/subtract/multiply/ divide the point data arrays of two datasets.
Having written now a very simple version which just adds the point data,
I try to build it as a Plugin and I get the error
Linking Cxx Shared Library ...\bin\libDataCalculator.dll
Creating library file: ..\bin\libDataCalculator.dll.a
CMakeFiles\DataCalculator.dir\vtkDataCalculator.obj: In function
'ZN17vtkDataCalculator3NewEv':
C:/ParaviewSource/ParaView3/Plugins/vtkDataCalculator.h:14 undefined
reference to 'vtable for vtkDataCalculator'
collect2: ld returned 1 exit status
I believe that I miss to specify a Macro, I just put
vtkTypeMacro(vtkDataCalculator,vtkDataSetAlgorithm);
in my Headerfile.
If there is a Macro missing, does anyone know, which one?
And if it´s something else .. what´s wrong?
thx for help,
Natalie
