[Paraview-developers] Linking error - ParaView plugin not buildable

[moder22 at hush.com]

Unfortunately not...  

	int vtkTestSource::RequestInformation(vtkInformation *reqInfo,
vtkInformationVector **inVector, vtkInformationVector *outVector)
{
 if(this->vtkPolyDataAlgorithm::RequestInformation(reqInfo,inVector,outVector))
  return 0;

	    vtkInformation *info = outVector->GetInformationObject(0);

	    double tRange[2] = {stepValues[0], stepValues[steps-1]};
    info->Set(vtkStreamingDemandDrivenPipeline::TIME_RANGE(), tRange,
2);
    info->Set(vtkStreamingDemandDrivenPipeline::TIME_STEPS(),
stepValues, steps);
   
info->Set(vtkStreamingDemandDrivenPipeline::MAXIMUM_NUMBER_OF_PIECES(),
-1);

	    return 1;
}
	int vtkTestSource::RequestData(vtkInformation *reqInfo,
vtkInformationVector **inVector, vtkInformationVector *outVector)
{
    vtkInformation *outInfo = outVector->GetInformationObject(0);
    vtkPolyData *output =
vtkPolyData::SafeDownCast(outInfo->Get(vtkDataObject::DATA_OBJECT()));

	    if (!output)
        return 0;

	    double time = 0.0;
    if
(outInfo->Has(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEP()))
        time =
outInfo->Get(vtkStreamingDemandDrivenPipeline::UPDATE_TIME_STEP());

	    output->Initialize();
    output->GetInformation()->Set(vtkDataObject::DATA_TIME_STEP(),
time);
    this->setPolyData(time, output);

	    return 1;
}
Any other ideas?Chris

adding implementations for RequestInformation and RequestData in
the testplugin.cpp file. Does that help?
