emerge -e @world would not have fixed it unless you emptied it first.

Hi Stroller,
Thanks, (and apologies for the delay).
World file was empty at the time of the previous post - I was still working
on fixing @system.
As mentioned, I was careless with copying over /var from a previous
install. The problem wasn't with the world file, but with the db/pkg lists.
emerge -e did not immediately fix it. However, with patience and a few
continuous fixes, I now have @system back - and am currently waiting for my
previous world packages to finish. Hopefully by tomorrow morning, I should
be able to complete a depclean without issue...

I wish! Sorry - until I have a 'proper' system working again, I am stuck
with webmail... :(

Thanks again for everyone's help.

Could you `grep -i gcc /var/lib/portage/world*` please?

A copy of the whole world file(s) would be great, in fact, ideally as plain 
text attachments.

Also, any chance you could set your mailer to send only plain text emails to 
the list?

Here ya go.

--emptytree (-e)
Reinstalls  target  atoms  and  their  entire  deep dependency tree, as
though no packages are currently installed. You should run this with
--pretend first to make sure the result is what you expect.

I'm too lazy to look it up myself and long ago stopping trying to
remember minutia, but search the man page for "empty". That's where it
is :-)

Just the one line:

I *think*, that with little time and patience, I can now sort this out.
Thanks for the emerge -e hint. It doesn't seem to be in the emerge man
page, though. What is the long-option name?

Kind regards,

If you copied over /var/db/pkg you have a rather confused and messed up
system. The safest way to recreate it is probably to move the pkg
directory elsewhere and then run "emerge -e @world".

gcc is slotted, so emerging 4.9.4 will not touch your 5.4.0 installation,
you use gcc-config to choose which one to use. What does gcc-config -l
show?

Re: [gentoo-user] Emerge @system causing gcc downgrade

[White, Phil]

Hi Neil,

Well, this is a new install.
Used Stage3-i686-20170214.tar.bz2
There is nothing in package.accept_keywords that is currently installed (as
far as I know - although it is possible that I might have added ~x86 to
gcc, although in this instance I don't believe that i did)
I have installed some packages, but removed them also (been having problems
with perl)
So currently, updating @world is the same as @system

OK - talking this through is helping. I *have* done something strange here.
The currently installed version is 4.9.4 (from gcc --version), except that
portage believes that 5.4.0 is installed.
My guess is that, since I am trying to rebuild an old system (due to a
hard-drive fail), I have accidentally copied over files that do not belong.
My guess is a completely useless /var/db/pkg/* is confusing the hell out of
portage/emerge.

So - any suggestions how to fix this mess?
Bite the bullet, emerge gcc, and then do a depclean - or can I convince
portage that gcc 4.9.4 is really here?

Thanks,
Phil

4.9.4 is the latest stable. Are you running a stable system with some
packages in package.accept_keywords? If so, and you gave a specific
version of gcc, it is possible that version is no longer in the tree -
5.4.0-r2 was recently removed.

Use the ~ operator when specifying versions to allow for minor updates

~sys-devel/gcc-5.4.0

or, in the case of gcc, you can specify a slot

sys-devel/gcc:5.4.0

Sorry Alan, that results in no extra information from emerge.
Still only gcc listed for installation - and nothing else.
