[/lib64/libstdc++.so.6: version 'GLIBCXX_3.4.21' not found]

Yessir I did. I tried to apply the solution in that thread to my issue. My GCC version is 7-3. Thanks for the bump!

Has anyone else ran into a similar issue before that may be able to help?

Good afternoon,

New admin here on CentOS 7. I found a similar thread from 2017 that had a solution for gcc5ish and could not figure out a way to apply that solution to my issue above.
