I'd suggest you first do a clean gcc upgrade to gcc-6.4.0 or gcc-7.2.0 depending on whether you run a stable or a testing system. https://wiki.gentoo.org/wiki/Upgrading_GCC And then follow exactly the steps in the news item after the step of rebuilding gcc. Or in detail: Run these commands: # gcc-config -l # gcc-config set <number of the latest gcc profile> # emerge -1 sys-devel/gcc # gcc-config -l # gcc-config set <number of the latest gcc profile> # source /etc/profile # emerge -1 sys-devel/libtool # gcc --version # emerge --depclean =sys-devel/gcc-<versionnumber> [for all installed gcc versions except for the latest (6.4.0 or 7.2.0)] # emerge -1 sys-devel/binutils # emerge -1 sys-libs/glibc # emerge -e @world Heiko
