[Insight-users] itkGradientVectorFlowImageFilter problems at compilation

[Luis Ibanez]

Hi Julien,

What version of ITK are you using ?

The current test for this filter is working
fine on the Dashboard...

Could you please post a minimal (but complete)
example of code that is producing this compiler
error.


Thanks


    Luis
