[Insight-users] typedef name cannot follow class/struct/union

[Neil.Burdett at csiro.au]

Hi Bill and Dan,
        thanks for the reply, but removing typename, or replacing it with ITK_TYPENAME gives exactly the same error in visual studio 2008;

"error C2242: typedef name cannot follow class/struct/union"

The full extract of code I'm using is;

  // Compute the seed image, by closing cavities and holes with an ultimate skeleton of the cuboid image
  typedef typename itk::UltimateSkeletonImageFilter<TOutputImage, TOutputImage, itk::Connectivity<Dimension, 0>, DistanceImageType > SeedSkeletonFilterType;
  itk::UltimateSkeletonImageFilter<TOutputImage, TOutputImage, itk::Connectivity<Dimension, 0>, DistanceImageType > SeedSkeletonFilterType;

  typename SeedSkeletonFilterType::Pointer seedSkeletonFilter = SeedSkeletonFilterType::New();
  seedSkeletonFilter->SetInput(cuboidImage->GetOutput());
  seedSkeletonFilter->SetPriorityImage(distanceInvertIntensityFilter->GetOutput());
  seedSkeletonFilter->SetInhibitImage(parallelSkeletonFilter->GetOutput());
  try{
    seedSkeletonFilter->Update();
  } catch(itk::ExceptionObject &ex) {
    throw itk::ExceptionObject("milxTopologicalHolesFilling", 0, std::string("Topological holes filling.. seed ultimate skeleton failed: ") + ex.GetDescription());
  }

Neil

I think the typename can be removed on both Windows and linux. My
general rule for typename is that it is required if there are no
template variables.

For example

typedef Foo<bar> FooBarType;

typedef typename Foo::Pointer FooPointer;
