hi folks,
I'm in new installation and I'm follow that guide about upgrade gcc : https://wiki.gentoo.org/wiki/Upgrading_GCC
the commands :
Install new version of compiler
emerge -u sys-devel/gcc
show the versions
gcc-config -l
choose the new version
gcc-config 2
reinstall libtool
emerge --ask --oneshot sys-devel/libtool
remove the old version
emerge --ask --depclean =sys-devel/gcc-4.9.3
until here all fine and perfect, but my doubt is about recompile the toolchain, I need just recompile the depedencies with
revdep-rebuild --library 'libstdc++.so.6' -- --exc
