[gentoo-user] how to upgrade perl

Hi,

how do you do an update despite perl blocking it?


emerge -a --update --newuse --deep --with-bdeps=y --keep-going @world

It seems that some pppl found perl 5.24 somewhere, which doesn't seem to
be available:

An update is overdue.  What should I do?

Try perl-cleaner, read the man page to see all the options.

[gentoo-user] how to upgrade perl

[Anton Shumskyi]

[-- Attachment #1: Type: text/plain, Size: 2190 bytes --]

In my case perl-cleaner was quite useless=( but it has an update since
then, so maybe it will work now.

But if it will be blocking updates you can always do it in some brutal
way=)))
run emerge perl with "--nodeps" and after do the same for every package
that uses perl....
you can find their files at /usr/lib64/perl5/vendor_perl/5.20.2/ and use
something like
portageq owners / /usr/lib64/perl5/vendor_perl/5.20.2/*
to find all packages that need reinstall, again if perl-cleaner won't work

simple emerge won't help, because it will try to compile some packages in
wrong order

and I have perl 5.24, using that repo
/etc/portage/repos.conf/gentoo.conf
[gentoo]
location = /usr/portage/gentoo
sync-type = git
sync-uri = https://github.com/gentoo-mirror/gentoo.git
auto-sync = true

Your tree is way behind, 5.24 has been out for ages (or maybe you just 
need eix-update to be run)

A perl update is a large operation and the devs need to put in a lot of 
work before everything is ready. This one was especially troublesome for 
me, it took a few days of --sync before it all smoothed out

* Try adding the option --backtrack=1000

* DON'T listen to people telling you to use perl-cleaner. 
  perl-cleaner is for *after* the upgrade, *not* *before*

* Your tree is outdated. 
  Perl 5.24.0 is in ~arch, Perl 5.22.2 is about to be stabilized

Your problem is likely not in perl itself, but in subslot deps
resolution. Looks like you have other unresolved dependencies, but
they can't be seen because of subslots. To solve this one needs to
temporary disable subslots, fix all issues, then enable subslots back.

First run emerge with subslots ignored:
  emerge -DNuav --with-bdeps=y --ignore-built-slot-operator-deps y --backtrack 10  @world 

After this command you will see other blockers than listed in your
mail. Fix them until the command above will build dep tree without
errors. Afterwards run your usual emerge command with subslots
enabled, e.g.:
  emerge -DNuav --with-bdeps=y --backtrack 10  @world 
and you should be fine.

See also bug 540562:
https://bugs.gentoo.org/show_bug.cgi?id=540562

This problem may be solved with huge backtrack value, but in my case
--backtrack=100 was not enough and 1000 was not possible to check,
because even 100 took about 3 hours(!!) to run.

Best regards,
Andrew Savchenko
