Software Collections technology provides a simple non-intrusive way to install modern/non-default software packages on CentOS/RHEL 6. GCC is notorious for taking a long time to build from source. This guide will help you quickly install a software collection named devtoolset-3-toolchain that includes GCC-4.9.2. These instructions are based on the instructions at https://www.softwarecollections.org/en/scls/rhscl/devtoolset-3/.
First, install the CentOS software collections repository, and then install the toolchain part of the Devtoolset-3 software collection.
yum update yum install centos-release-scl-rh yum install devtoolset-3-toolchain
To enable the devtoolset software collection in a bash shell do the following:
scl enable devtoolset-3 bash
Alternatively, you can run a single command in the software collection like this
scl enable devtoolset-3 ‘gcc -v'
