It has been long after releasing the GNU GCC 8.x, but at last, there is a trusted repository, which has offered us packages for GNU GCC 8.x, which won’t break your system! Many of us prefer CentOS 7 because it offers free enterprise-class operating system and as mentioned in our article before – How to install new gcc and development tools under CentOS 7 there are a couple of approved external repositories for CentOS, which you can trust https://wiki.centos.org/AdditionalResources/Repositories. In one of them Software Collection – https://www.softwarecollections.org/en/scls/ several months ago the GNU GCC 8.x packages were added!
At present, the GNU GCC version is gcc (GCC) 8.3.1 20190311 (Red Hat 8.3.1-3).
Here are the steps how you can install GNU GCC 8 and how you can use it:
STEP 1) Update your system and install the repository in your system
The commands:
1 2 | yum update -yyum -y install centos-release-scl |

STEP 3) Use the installed tools.
Because using such a package with multiple complex packages you must configure multiple environments and links to the versions you installed replacing the ones from your base system, but the package comes with a handy tool, which executing it will configure everything and you are ready to go!
1 | scl enable devtoolset-8 bash |
Whenever you want to use the new GCC you must execute it or you will end up with the default one.

Using Software Collection you could install multiple GNU GCC version 6, 7 (we have article on the subject – How to install new gcc and development tools under CentOS 7) and now 8.
