[gentoo-user] --depclean and sys-devel/gcc

[allan gottlieb]

I run a stable system so am surprised to see that eix reports
I have gcc version ~7.3.0-r3 installed.  (gcc-config -l reports
that stable x86_64-pc-linux-gnu-6.4.0 is the active compiler)

More surprising is that
   emerge --depclean --pretend sys-devel/gcc
wants to remove everything *except* the testing/nonstable 7.3.0-r3

grep -r gcc /etc/portage
has no hits.

@system and several installed packages require gcc but all would be
satisfied by stable 6.4.0-r1 my active compiler

# emerge --depclean --verbose --pretend sys-devel/gcc

Calculating dependencies... done!
  sys-devel/gcc-7.3.0-r3 pulled in by:
    @system requires sys-devel/gcc
    dev-java/icedtea-bin-3.6.0 requires >=sys-devel/gcc-5.4.0
    net-libs/webkit-gtk-2.20.4 requires >=sys-devel/gcc-4.9
    sys-devel/llvm-4.0.1-r1 requires >=sys-devel/gcc-3.0
    sys-devel/llvm-5.0.2 requires >=sys-devel/gcc-3.0
    sys-devel/llvm-6.0.1 requires >=sys-devel/gcc-3.0
    sys-libs/glibc-2.26-r7 requires >=sys-devel/gcc-4.9

>>> These are the packages that would be unmerged:

 sys-devel/gcc
    selected: 4.9.3 4.9.4 5.4.0-r3 6.4.0-r1 
   protected: none 
     omitted: 7.3.0-r3 

Am I supposed to
   emerge --unmerge =sys-devel/gcc-7.3.0-r3
?

thanks in advance,
allan

PS I moved some months ago to the 17.0 profile and did the
make --emptytree @world

gcc-7.3.0-r3 is stable, you probably updated your ::gentoo repository
without updating eix. Run eix-update and check again.

Thank you!

If I now upgrade with

    gcc-config x86_64-pc-linux-gnu-7.3.0
    env-update && source /etc/profile
    emerge --ask --oneshot sys-devel/libtool

must I do a world update --emptytree as when converting to the 13.0
profile.

I believe not as the requirement when upgrading to 13.0 was due to the
new generation of PIE output.

Again, thank you.

It's recommended, but not something you have to do immediately. It's 
best to do it when you don't need the machine (like overnight), but if 
you happen to be using it while the world rebuild is going on, use these 
in your make.conf:

PORTAGE_NICENESS=19
PORTAGE_IONICE_COMMAND="sh -c \"schedtool -D \${PID}; ionice -c 3 -p 
\${PID}\""

(Make sure sys-process/schedtool is installed.)

This makes sure the emerge process does not slow down your normal use of 
the machine.

Thank you.  I started my backup machine on the world update.
Will do the main machine afterward.
