Sorry:
I did it:
[root@localhost holger]# yum install gcc-4.8.5-16.el7_4.2.x86_64
Loaded plugins: fastestmirror, langpacks, nvidia, replace
Loading mirror speeds from cached hostfile
* base: centos.mirrors.as250.net
* elrepo: ftp.nluug.nl
* epel: ftp.fau.de
* extras: ftp.rrzn.uni-hannover.de
* ius: mirror.amsiohosting.net
* remi-safe: nl.mirror.babylon.network
* updates: mirror1.hs-esslingen.de
Package gcc-4.8.5-16.el7_4.2.x86_64 already installed and latest version
Nothing to do
[root@localhost holger]#
What must I do next?
Greetings,
H.Steffen
