Hi all,

While compiling a simple ITK example from the ITK website, I’m receving a set of error messages related to itk::NumericTraits.

Example:

member “itk::NumericTraits::One” may not be initialized

Although this not influence the program (I can run it), I would like to remove this error from my compilation. Do you have a suggestion?

Hi @pedromorais17,

Welcome to the ITK Community! 😄

Sharing the specific message will help confirm, but this sounds like a familiar compiler warning instead of an error; this particular warning can be safely ignored.

However, please try [ITK 5.0 RC2](https://discourse.itk.org/t/itk-5-0-release-candidate-2-spatial-objects/1832) – the warning should be addressed there.
