[Insight-developers] std::_Copy_impl warning when building against ITK with MSVC 2010

[David Doria]

When I build even something very very simple like this with the MSVC
2010 compiler:

#include "itkImage.h"
#include "itkImageFileReader.h"

int main(int argc, char *argv[])
{
  typedef itk::Image< double, 2 >         ImageType;
  typedef itk::ImageFileReader<ImageType> ReaderType;

  ReaderType::Pointer reader = ReaderType::New();
  reader->SetFileName(argv[1]);
  reader->Update();

  return EXIT_SUCCESS;
}


I get:

----------------------
C:\Program Files\Microsoft Visual Studio
10.0\VC\INCLUDE\xutility:2227: warning: C4996: 'std::_Copy_impl':

the caller to check that the passed values are correct. To disable
this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how

Has anyone seen this? Is this D_SCL_SECURE_NO_WARNINGS something that
should be added to ITKSetStandardCompilerFlags.cmake? Or is there a
better explanation?

Thanks,
