The default gcc compiler collection that comes with Centos 7 is a version 4.8.5 from 2015. It is OK for the most of our educational work. But in order to be able to use the latest version of especially C++ language it could be handy to upgrade the GCC Compiler Collection.
Execute this:
[~] $ sudo yum install centos-release-scl
This opens for a repository that contains a newer version of the development tools.
Next execute:
[~] $ sudo yum install devtoolset-7
Now in order to use the new toolchain you must run a small utility program, that sets up the environment. Try execute
[~] $ scl enable devtoolset-7 bash
This will start a new bash shell with the new toolchain enabled.
In order to start Eclipse using the toolchain execute this:
[~] $ scl enable devtoolset-7 /opt/eclipses/eclipse-cdt/eclipse
provided that you have installed your version of Eclipse in the above shown path - if not customise to your needs.
Finally, if you want to permanently use the new toolchain you can edit the icon in the start menu.
