Should probably instruct users to upgrade all packages first because it can be, as I’ve experienced, nearly impossible to upgrade GCC if the world isn’t up to the latest stable. An ‘emerge -avuDN world’ should do the trick as a first step. > Then, > * Select the new profile with eselect > * Re-emerge, in this sequence, the selected gcc, binutils, and glibc > emerge -1 sys-devel/gcc:6.4.0 > emerge -1 sys-devel/binutils > emerge -1 sys-libs/glibc Some of these can take a while. Maybe we want to spell it out: for p in sys-devel/gcc:6.4.0 sys-devel/binutils sys-libs/glibc; do emerge -1 $p || break done
