gcc and intel's icpc on redhat do not recognize namespace std::literals;

I get an error that ‘literals’ is not a namespace-name when compiling the following

#include <complex>
using namespace std::literals;
...

its compiles fine on Windows with MSVC and even on OS X with clang, but fails on redhat 7 using either gcc and intel's icpc.

some more detail:

the system

 cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

gcc version

gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-4)

Intel compiler version

icpc --version
icpc (ICC) 16.0.3 20160415
Copyright (C) 1985-2016 Intel Corporation.  All rights reserved.

compiler call

gcc filename.cpp -std=c++1y
icpc filename.cpp -std=c++14

what am I missing?

ps: Even simple code like in this live demo doesn't work:(

Solution

libstdc++ that comes with GCC 4.8.x does not have those literals; they started shipping beginning with GCC 4.9.0.
