[Insight-users] ITK windows compilation error

Hi Brad,

Thank you for your answer.

I included "itkNumericTraits.h", and it did not change the error.

Something I forgot to precise is that the tool compiles without errors on linux (Ubuntu 12.10) and Mac, so I think it is specific to the compiler from Visual Studio 2008.

The weird part is that it seems to look for NumericTraits in "itk::itk", which I assume is wrong:
"
error C2039: 'NumericTraits' : is not a member of 'itk::itk'
"
I have no idea of where it can come from.

By the way, the code of my tool is here<https://www.nitrc.org/plugins/scmsvn/viewcvs.php/branches/Slicer4Extension/?root=dtiprocess>. The file "tensorscalars.cxx" is in PrivateLibrary/tensorscalars.cxx

Thanks,
Adrien

Hello,

My first guess would be that it's a missing include.

Did you including "itkNumericTraits.h" before itkVectorIndexSelectionCastImageFilter.h. If that is the problem then it looks like there is a missing include in the ITK header.

Hello everybody,

I try to compile a tool (dtiprocess) using ITK (ITKv4.3.0 from git://itk.org/ITK.git<UrlBlockedError.aspx>, commit from 12-16-2012 13:05:15) on Windows (Windows 7 with Visual Studio 208).
ITK compiled without any problem, but the tool fails to compile and gives me an error in one of the ITK classes:

The part of the tool's code where the error appears is:
(tensorscalars.cxx:93)
"
#include "itkVectorIndexSelectionCastImageFilter.h"

 (...)

template<>
itk::Image<double, 3>::Pointer createLambda<double>(TensorImageType::Pointer timg, // Tensor image
                                                    EigenValueIndex lambdaind) // Lambda index
{
  // Not really a deformation image output jsut a 3-vector of doubles.
  typedef itk::FastSymmetricEigenAnalysisImageFilter<TensorImageType,DeformationImageType> LambdaFilterType;
  LambdaFilterType::Pointer lambdafilter = LambdaFilterType::New();
  lambdafilter->SetInput(timg);
  lambdafilter->OrderEigenValuesBy(LambdaFilterType::FunctorType::OrderByValue);
  lambdafilter->Update();

(l.93)  typedef itk::VectorIndexSelectionCastImageFilter<LambdaFilterType::OutputImageType, RealImageType> ElementSelectAdaptorType;
  ElementSelectAdaptorType::Pointer elementSelect = ElementSelectAdaptorType::New();
  elementSelect->SetInput(lambdafilter->GetOutput());
  // Reverse semanatics of lambda_1 from ITK.
  // In our convention lambda_1 is the largest eigenvalue whereas in
  // ITK its the smallest
  elementSelect->SetIndex(2 - lambdaind);
  elementSelect->Update();

  return elementSelect->GetOutput();
}
"

I did not write the tool myself, but I think the problem comes from the tool and not from ITK, I just can not figure out what I need to change to make it compile.
Does anyone have any ideas ?

Thanks,
