I’m making a patch for this. I’ve noticed this today as well.
mkdir XX; cd XX; cmake -DCMAKE_CXX_STANDARD:STRING=11 ../ITK; make –j23 Before this patch, there was a build failure. After this patch it is now building. I made modifications to more closely match upstream VXL.

Thank you for contributing. Can you please submit the patch to ITK Gerrit for review? http://www.itk.org/Wiki/ITK/Git/Develop Thanks Brad On Jan 13, 2016, at 6:47 PM, Isaiah Norton <isaiah.nor...@gmail.com<mailto:isaiah.nor...@gmail.com>> wrote: (cc: insight-devel) We are also seeing this issue, and several SimpleITK dashboards are failing with the same error for the OS X 10.9 (since bumping to ITK 4.9) and 10.10 (since yesterday) dashboards: https://open.cdash.org/buildSummary.php?buildid=4188623 It looks like this is essentially caused by SimpleITK being compiled with `-std=c++11`, whereas ITK (and VXL) are not. So, there is a mismatch between the configured definition of `VCL_CONSTEXPR` and the `VCL_STATIC_CONST_INIT_*` macros. For reference, VCL_CONSTEXPR was introduced here: http://review.source.kitware.com/#/c/20386/ A proposed patch [1] is attached.
