Which version of GCC to use with ICPC?

Hi,

I'm using XE Composer 2017 on a current CentOS machine (7.2.1511) from Colfax.

Unfortunately working with ICPC in this setting is a pain, since it piggybacks on top of the installed GCC and its libstdc++. The GCC version 4.8.5 that ships with CentOS is positively ancient -- its C++11 support is not feature complete, and it does not support C++14 at all.

Thus I'm trying to install a new version of GCC & libstdc++ and get ICPC to work on top of that. I initially tried the HEAD version of gcc, but that does not work at all -- presumably it uses some features that are not yet supported by icpc.

Thus my question: what is the most up-to-date version of GCC & libstdc++ that is compatible with the Intel compiler? What steps do I need to take to get icpc to use that?

Thank you and best regards,
Wenzel
