Hi all,

ITK master was working for me about a week ago. Now I’ve updated and rebuilt and it seems that vxl\_config.h is no longer installed in include/ITK-5.0 but rather in include/vxl/core.

I assume that’s a bug, yes?

Thanks,

Sean

I was just working on it. This is what I am currently testing:
