The C++11 library implementation was not complete until GCC 5 (and so C++11 was still marked experimental). When C++11 is used there are incompatible changes between 4.8 and 4.9, and between 4.9 and 5. > I am asking about this 'ancient' release, as it is the standard > > compiler in RHEL 7.5 and we are wondering, if it is safe to > > turn on C++11 in an operational system. See your RHEL documentation for questions about the RHEL compiler and what's supported in RHEL. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/developer_guide/gcc-compiling-code#gcc-compiling-code_understanding-cpp-compatibility-redhat You can use the Red Hat Developer Toolset if you want to use C++11 and still get support through your RHEL subscription.
