I'd suggest you first do a clean gcc upgrade to gcc-6.4.0 or gcc-7.2.0 |
| 34 |
depending on whether you run a stable or a testing system. |
| 35 |
|

https://wiki.gentoo.org/wiki/Upgrading_GCC |
| 37 |
|
| 38 |
And then follow exactly the steps in the news item after the step of |
| 39 |
rebuilding gcc. |
| 40 |
|
| 41 |
Or in detail: |
| 42 |
|
| 43 |
Run these commands: |
| 44 |
# gcc-config -l |
| 45 |
# gcc-config set <number of the latest gcc profile> |
| 46 |
# emerge -1 sys-devel/gcc |
| 47 |
# gcc-config -l |
| 48 |
# gcc-config set <number of the latest gcc profile> |
| 49 |
# source /etc/profile |
| 50 |
# emerge -1 sys-devel/libtool |
| 51 |
# gcc --version |
| 52 |
# emerge --depclean =sys-devel/gcc-<versionnumber> [for all installed |
| 53 |
gcc versions except for the latest (6.4.0 or 7.2.0)] |
| 54 |
# emerge -1 sys-devel/binutils |
| 55 |
# emerge -1 sys-libs/glibc |
| 56 |
# emerge -e @world |
| 57 |
