I'm on gcc-7.3.0-r3 and have not noticed any problems on 3 boxen so far. > As https://wiki.gentoo.org/wiki/Upgrading_GCC > still do not have any specific instructions on > switching to gcc version 7.3, I am still afread > of switching to gcc version 7.3 and would like > to ask if anybody encountered some problem > after switching to gcc version 7.3 and which > packages should be rebuild after such switching. > > Thank you in advance for your help. I didn't have to rebuild anything, but if you have reasons to fear breakage you can rebuild your toolchain: 1. Use gcc-config to select x86_64-pc-linux-gnu-7.3.0 2. Re-source /etc/profile by running in your current console/terminal: . /etc/profile 3. Re-emerge libtool: emerge -1 sys-devel/libtool 4. Re-emerge the following packages in this order: emerge -1 sys-devel/gcc-7.3.0-r3 emerge -1 sys-devel/binutils emerge -1 sys-libs/glibc 5. You could if you want re-emerge your entire system, 'emerge -e @world' or if you would rather conserve electricity wait as different packages come up for an update over time. If my experience to date holds true and for a general purpose desktop none of the above rebuilds are necessary, other than switching your gcc to 7.3.0. -- Regards, Mick
