Hello Luc, Thanks for looking into this.
This bug is related to the older GCC 4.1 compiler that is found standard with Redhat 5 and Fedora 5 and used for distributions such as Anaconda’s Python. I apologize for the incorrect version before. Here is some ITK code to reproduce the error: http://review.source.kitware.com/#/c/20674/ Thank you for exploring a minimal test case. Your code does compile and run OK with GCC 4.1. As a work around for SimpleITK I have disabled the SimpleITK Explicit library for now [1], this is not an optimal solution, and we should try to get explicit instantiation working again with GCC 4.1 Brad https://github.com/SimpleITK/SimpleITK/compare/next#diff-af3b638bc2a3e6c650974192a53c7291 > On Jan 20, 2016, at 4:39 AM, Luc Hermitte <luc.hermi...@c-s.fr> wrote: > > Le 20/01/2016 09:57, Luc Hermitte a écrit : >> Hello, >> >> Le 19/01/2016 21:19, Bradley Lowekamp a écrit : >>> Hello, >>> >>> My release builds for SimpleITK are having significant problems with the >>> change done here [1] to the itkStaticConstMacro. >>> >>> My builds on Redhat 5, with gcc 5.1, are filling my disk with errors >>> along the following: >>> [...] >> [...] > >>> I’ll look into alternatives... >> >> Can you isolate the error on a simple test case that reproduce the issue? > > I've tried the file attached on https://ideone.com/SGlJ1i but it seems > valid with GCC 5.1. > > However, in C++11, constexpr is required.
