[Insight-users] Problem with itkConvolutionImageFilter from git

[Cory Quammen]

Jothy,

I understand that you are copying files from git to the 3.20 source.
Is that correct? If so, that sounds dangerous to me, and my best
advice to you is to stick with one version.

For what it's worth, the ConvolutionImageFilter tests are compiling
fine within the current source in git on the compilers ITK supports,
and the method giving you the error is being exercised by the tests.
My guess is that there is a problem with mixing source between
versions. There are many changes in git, and I wouldn't be surprised
if doing what you are doing causes problems.

Would it be possible for you to switch completely to the source in git?

Thanks,
Cory
