I'll look into this. Normally I compile on clang or gcc > 6.0. I'll see whether it is feasible to support gcc 5.x without significant changes.

[xelatihy]

This is a c++11 issue in gcc < 6, How important is support for c++11? I looked at all of yocto and c++14 helps a lot. I could switch many c++14 features off, but I am not sure what is the real gain. What do you think?

[xelatihy]

The development branch copmpiles as C++11 on clang. I will close this.
