When installing a new system (I used https://ftp.uni-erlangen.de/gentoo/releases/amd64/autobuilds/current-stage3-amd64/stage3-amd64-20160922.tar.bz2) and you try to upgrade world to ~ARCH =sys-devel/gcc-config-1.8-r1 fails to emerge:

...the error goes away after switching binutils from x86_64-pc-linux-gnu-2.25.1 to x86_64-pc-linux-gnu-2.26.1.

Comment 1 Fernando (likewhoa) 2016-12-26 22:36:08 UTC

confirmed here but it's also broken with =sys-devel/binutils-2.27 and switching to 2.26 doesn't work as stated above.

Comment 2 Fernando (likewhoa) 2016-12-27 15:01:09 UTC

dup of #603798

This is not a dupe. Bug 603798 was about the faulty pre gcc-5.5.0 patch set.

you haven't posted emerge info, so i can only guess at settings here

what version of gcc ?  binutils ?  did you upgrade binutils, upgrade gcc, then switch binutils to an older version ?

1) I extracted stage3-amd64-20160922.tar.bz2 which had =sys-devel/gcc-4.9.3 and =sys-devel/binutils:2.25.1 at this time.

2) I chroot into the new system

3) Adjusted some basic files like /etc/timezone, /etc/locale.gen, /etc/conf.d/hostname, /etc/hosts, /etc/dispatch-conf.conf, /etc/fstab.

4) I set CFLags following https://wiki.gentoo.org/wiki/Safe_CFLAGS#Find_CPU-specific_options, in my case I set

CFLAGS="-O2 -pipe -march=ivybridge  -mtune=ivybridge"

5) I changed

ACCEPT_KEYWORDS="amd64"

into

ACCEPT_KEYWORDS="~amd64"


6) I updated gcc:

# emerge --ask --oneshot --update sys-devel/gcc
# gcc-config -l
# gcc-config 2
# env-update && source /etc/profile
# emerge --oneshot sys-devel/libtool
# emerge --prune --ask sys-devel/gcc
# /usr/share/gcc-data/x86_64-pc-linux-gnu/5.4.0/fix_libtool_files.sh 4.9.3

(the last command found nothing)


7) Now I tried to update world, i.e.

# emerge --ask --verbose --update --deep --with-bdeps=y --newuse world

...and while updating world (well, you first have to update perl/python on your own...) sys-devel/gcc-config-1.8-r1 failed with the shown output.

This was reproducible.

The problem went away after updating binutils manually (emerge -a1 sys-devel/binutils && eselect binutils list && eselect binutils set 2 (which was sys-devel/binutils-2.26.1 at this time)).

Has anyone seen this problem in the wild lately? Should this block stabilization in bug 626646?

That bug is not specific to gcc-config. It's a case when glibc is built with too new binutils: https://bugs.gentoo.org/622690
