I need to build u-boot on my CentOS 7 machine but encounter this:
*** Your GCC is older than 6.0 and is not supported
I've updated the installation on my machine but the current version is:
gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-36)
How do I go about updating gcc to version 6 or greater on my CentOS 7 machine? And do so safely?
