How to install C++11 C++0x header files on Redhat Enterprise

Question

I moved my application to another Linux box, after compilation, it returns an error saying

#include <atomic>

can not be resolved.

I guess the new GNU C++11 header files / libraries are not installed on new machine.

My question is how can I install them?

I am running on Redhat Enterprise, so yum install ?

Thanks.

Have you added `--std=c++0x` or `--std=c++11` if GCC version is >= 4.7? — Rafał Rawicki, Mar 21 '12 at 19:36
Search the repo, rpmfusion..etc. If not present, build it yourself without rooting (otherwise it 'can' be a disaster). — manasij7479, Mar 21 '12 at 19:50

The Red Hat Developer Toolset provides C++11 support.

(Indeed, I suspect this is the primary reason for its existence.)

+1 Very nice. There is a CentOS test version here: http://people.centos.org/tru/devtools/ – trojanfoe Nov 28 '12 at 09:37
Yes, but you should still be careful about mixing binaries built in C++11 mode with binaries built with an older compiler in C++98 mode.

The include under the version of gcc that comes with RHEL 6 is:

#include <cstdatomic>

See Runtime Library (libstdc++) section of gcc 4.4 releaste notes.

EDIT: This answer is not fully correct, because cstdatomic is the C11 file and not the C++11 one. For full C++ support in RHEL 6, the devtoolset should be used.

Interesting, but that is not the same thing as C++11 ``. See http://stackoverflow.com/questions/17185734/. – Nemo Feb 27 '14 at 17:52
@Nemo, in fact it's very similar, the answers to the question you link to are wrong. – Jonathan Wakely Dec 06 '14 at 17:01

Looks like you'll need to install an up to date version of GCC yourself; RHEL (at least as of 6.x) does not have a version of GCC supporting C++0x in it's repositories. You can build recent versions of GCC by following GCC's installation instructions, which are distribution-neutral.

You may also be able to use a package from a more recent Fedora release, which generally contains more "bleeding edge" software than that available in RHEL.
