Hi Folks, > GCC 8 is the system compiler in EL8, so there's no devtoolset-8 for CentOS 8 (or RHEL 8, for that matter). There should be a devtoolset-9 soon for EL8. My understanding is that Application Streams [1] is replacing Software collections for RHEL8 and therefore in C8. But it would be great if someone from Red Hat could clarify this point. One main difference is that SCLs can be installed in parallel while Application streams cannot.
