On an Amazon Linux 2 Docker image, "yum install gcc" installs gcc 7.3.1.
I want to install gcc 8. It seems it normally can be installed as part of "devtoolset-8" (https://www.softwarecollections.org/en/scls/rhscl/devtoolset-8/), but the instructions for either CentOS or RHEL seems not working on Amazon Linux.
So the only way to install gcc 8 on Amazon Linux is to install from source?
I also need the devtoolset-8-toolchain, how can that be installed?
