[Insight-users] ITKRegionGrowingPython and ITKDistanceMapPython Compile Errors on MSVS2008 to x64

[Constantine Zakkaroff]

Hello ALL,

When compiling ITK 4.2 with Python wrapping on MSVS2008 to x64 I get the 
following errors which come up during explicit instantiation with float:

Error	168	error C2665: 'itk::NumericTraits<T>::ZeroValue' : none of the 
2 overloads could convert all the argument types 
e:\temp\insighttoolkit-4.2.0\modules\core\imagefunction\include\itkVectorMeanImageFunction.hxx 
90	ITKRegionGrowingPython
Error	169	error C2665: 'itk::NumericTraits<T>::GetLength' : none of the 
2 overloads could convert all the argument types 
e:\temp\insighttoolkit-4.2.0\modules\core\imagefunction\include\itkVectorMeanImageFunction.hxx 
99	ITKRegionGrowingPython

And these errors come up during explicit instantiation with short, 
because fabs on MSVS doesn't cope with short:

Error	174	error C2668: 'fabs' : ambiguous call to overloaded function 
e:\temp\insighttoolkit-4.2.0\modules\filtering\distancemap\include\itkIsoContourDistanceImageFilter.hxx 
383	ITKDistanceMapPython
Error	175	error C2668: 'fabs' : ambiguous call to overloaded function 
e:\temp\insighttoolkit-4.2.0\modules\filtering\distancemap\include\itkIsoContourDistanceImageFilter.hxx 
387	ITKDistanceMapPython

Here's what MSVS2008 says about short passed to fabs:

618>        c:\Program Files (x86)\Microsoft Visual Studio 
9.0\VC\include\math.h(119): could be 'double fabs(double)'
618>        c:\Program Files (x86)\Microsoft Visual Studio 
9.0\VC\include\math.h(509): or       'float fabs(float)'
618>        c:\Program Files (x86)\Microsoft Visual Studio 
9.0\VC\include\math.h(557): or       'long double fabs(long double)'
618>        while trying to match the argument list '(short)'

I can see how to correct the errors on my machine, or instead I can try 
out patches if any are suggested.
