Could you bug them to... update CentOS? :)

Ouch. You definitely need to install and activate an appropriate
devtoolset as follows:

$ yum install centos-release-scl
$ yum install devtoolset-8

(Bug those people to at least install that). Then, put something like
this in your .bashrc:

$ source scl_source enable devtoolset-8

And you are ready to go with a fairly decent version of gcc, i.e.:

$ gcc --version
gcc (GCC) 8.3.1 20190311 (Red Hat 8.3.1-3)
