[Insight-developers] VS2010 and itkStdAlgorithm

[M.Staring at lumc.nl]

Hi,

I can confirm that ITK now builds with my VS2010:

Thanks for fixing this so quickly!

Regards, Marius

Perhaps a more sophisticated configuration checking technique would be to capture __cplusplus at configure time, and include it in itkConfigure.

Then at compile time (for both ITK and apps that use ITK) compare that captured value against __cplusplus to make sure they match.

Which would solve David Doria's problem, and the test in itkStdAlgorithm.h could be relaxed or eliminated.
