There is no support or guarantees when using the provided scripts. If you break your operating system, the only remedy is to re-install your operating system and start fresh again. Use at your own risk and yes there are risks. These scripts are no maintained or supported for GCC 7, 8, 9 after CentOS SCL Yum repos are available which they are available now.
- GCC 7.x, 8.x and 9.x compiler & Binutils build scripts for install and creation of RPMs for CentminMod.com LEMP stacks
- GCC 7.x, 8.x and 9.x snapshots are built from sources at http://www.netgull.com/gcc/snapshots/LATEST-7/ and http://www.netgull.com/gcc/snapshots/LATEST-8/ respectively using CentOS SCL devtoolset-7 provided GCC 7.2.1 compiler.
- CentOS 7.x only
- Optional support for Profile Guided Optimization based GCC builds for ~7-10% better performance for resulting binaries built
- GCC 8 as at 20180114 snapshot has added support for new GCC Retpoline patches to support new options for
-mindirect-branch,-mindirect-returnand-mindirect-branch-registerto address Spectre variant 2 vulnerabilities. - GCC 7.3 which is currently RC build will also add GCC Repoline patches. Once out of RC, will update script to build against GCC 7.3 branch.

/opt/gcc-7-20180111is symlinked to/opt/gcc7for easier reference as the GCC snapshot date timestamped builds increment- Using
/opt/gcc7/enableallows you to set PATH appropriately. Example gcc binary is at/opt/gcc7/bin/gccbut with source file enabled, can reference just asgcc
source /opt/gcc7/enable
or directly without symlink alias
source /opt/gcc-7-20180111/enable
gcc -v
