Dear Nektar users,

After a lot of trial and error, this is what I end up with trying to
compile the fresh development version of Nektar.
Here I reproducing the compile error since I encountered the same error on
an hpc cluster rhel6 and Gcc-8.2.0, same thing on my workstation Gcc-8.2.0
running Centos 6.10 64bits. nevertheless, release version 5.0 does compile
fine.
I've been trying to compile the development version with
nektar-error-on-warnings set OFF, with full build for all thirdparty
packages, I also had the same error using cxxflags=-std=c++11 trying to
limit the compiler features to c++11.

Would you please check out the compile error output attached hereafter.

Thanks to all of you.

Saâd
