Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am trying to install GROMACS on my workstation (centOS 6.3)
[root@mqml build]# cmake .. -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON
CMake Error at cmake/gmxTestCXX11.cmake:113 (message):
This version of GROMACS requires a C++11 compiler. Please use a newer
compiler or use the GROMACS 5.1.x release. See the installation guide for
details.
Call Stack (most recent call first):
CMakeLists.txt:164 (gmx_test_cxx11)
-- Configuring incomplete, errors occurred!

[root@mqml build]# how do I install C++11 ?
I think you will need to update your CentOS to get the newer compiler.
You can try using/setting the compile option to "-std=c11", but you better check that your version supports the standard.
If I do a "gcc -std=c11" (with no source), I get an error about their being no source, but if I use some random string instead of "c11" I get a "unrecognized command line option..." instead.
That should let you find out if c11 is supported by your current compiler.

There are extra later compilers avilable for CentOS 6 : 'devtoolset-4'.
But they use the system gcc-4.4.7 libs :
{/lib64/libgcc*, /usr/lib64/libstdc++*}, i.e. no C++11 support.
You can use "gcc53-c++-5.3.0-1.el6.x86_64.rpm" : Has internal libs ...
/ / /gcc53/lib64/{libgcc_s.so.1, libstdc++.so.6 -> libstdc++.so.6.0.21}

Provides /usr/bin/{gcc53, g++53} → → $ CC=gcc53 CXX=g++53 cmake ..
By the way, I got no C++11 text when testing gromacs-5.1.4 with gcc-4.4.7 :
Code:
cd build/ && cmake .. -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON
.
.
-- gcc 4.4.7 detected, using -O3, will apply workaround for optimization bug (disable with GMX_DISABLE_GCC44_BUG_WORKAROUND)
.

It is only for versions above 2016.1. How to upgrade to devtoolset 4.0?
Can I have the command?

Re #5.
All "devtoolsets" are using old files = {/lib64/libgcc*, /usr/lib64/libstdc++*}.
No C++11 support.
The 'gcc53-c++-5.3.0-1.el6.x86_64.rpm' (48.7MB) was built here, 'July 2016'.
Works very well with gromacs-2016.3 :
Code:
-- The C compiler identification is GNU 5.3.0
-- The CXX compiler identification is GNU 5.3.0
-- Check for working C compiler: /usr/bin/gcc53
-- Check for working C compiler: /usr/bin/gcc53 -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/g++53
