[gentoo-user] emerge conflict

[gentoo-user] emerge conflict

[Frank Schwidom]

Hi

i get the error:

{
!!! Multiple package instances within a single package slot have been
pulled
!!! into the dependency graph, resulting in a slot conflict:

media-libs/libpng:0

  ('ebuild', '/', 'media-libs/libpng-1.4.3', 'merge') pulled in by
    >=media-libs/libpng-1.2.43-r2:0 required by ('ebuild', '/',
    >'x11-libs/cairo-1.8.10', 'merge')
    >=media-libs/libpng-1.4 required by ('ebuild', '/',
    >'x11-libs/gtk+-2.20.1-r1', 'merge')
    (and 27 more)
}

And i wonder that it seems not to be possible to install both libs
(libpng-1.2.43-r2:0, libpng-1.4) in the same time. Linux is actually 
able to manage this by the lib-version and links.

Did i have overseen any gentoo switch that makes is possible? Or is
there any other option?

Regards

You have misread the portage output. It does not say it wants those versions. 
It says this:

  >=media-libs/libpng-1.2.43-r2:0
  >=media-libs/libpng-1.4

Note the greater than or equal to.

The limiting factor to multiple versions is not Linux, it is portage. Portage 
will not co-install two versions in the same SLOT.

This whole libpng mess was a right royal fuck up several months ago. I forget 
the specifics but IIRC a decent solution was

emerge -C libpng
emerge libpng
revdep-rebuild

The last step takes some time to complete, there is a lot of fall-out to deal 
with. 

As you are only hitting this now, I assume you have a stable system and are 
not using the masked versions of portage. @preserved-rebuild would save you 
lots of pain, but that feature is not available in stable versions of portage.

For more info, check the archives. There is more mail there about this than 
you could ever possibly want to read.

I actually hit this myself yesterday.
When emerging "libpng", it mentions a script that needs to be run. I would 
suggest running that script.

I think the following commands were the ones that led to a properly upgraded 
system. It is now working for me, but it did take quite a while.
**
emerge -vauD --newuse world
lafilefixer --justfixit
/usr/sbin/libpng-1.4.x-update.sh 
emerge -vauD --newuse world
revdep-rebuild -- -va
emerge -vauD --newuse world
**

Alternatively, you could always try to one that should always work:

emerge -vae world
(NOTE: This will rebuild _everything_)

Btw, if you are using KDE, you might, like me, also hit issues with akonadi 
not starting (I couldn't not use it anymore)
Post on the list if you hit it, I still have these fresh in my mind :)

This script is hopefully not the hack, that is said to be a problem in
the future?

Eeerh....
Not sure, guess I stopped reading too soon as I managed to get it to appear to 
be working...

Anyway, am currently doing a " emerge -vae world " as I want to get it all 
compiled using GCC 4.4. Guess that should 'fix' whatever damage that script 
does?

When flameyes says to do something X in regard to a build, and someone else 
says to do something different, then in almost all cases (regardless of how 
authoritative the other person sounds), you should do what flameeyes says.

ESPECIALLY the blog entry Daniel mentioned.

+1  His way of doing things has saved me issues several times.  Is the

This was a big problem maybe a couple of months ago? I'm surprised you
made it this far!

There are some instructions here that will likely help:

[gentoo-user] emerge conflict

[Philip Webb]

Starting my regular Sat system update, 'eix-sync' told me (equivalent) :

root:524 ~> eix ^perl$
[U] dev-lang/perl
 Available versions:  5.20.2(0/5.20) ~5.20.2-r1(0/5.20) ~5.22.0(0/5.22) ~5.22.1(0/5.22) 5.22.2(0/5.22) ~5.24.0(0/5.24) ~5.24.0-r1(0/5.24) {berkdb debug doc gdbm ithreads}
 Installed versions:  5.20.2([2015-10-04 11:34:10])(gdbm -berkdb -debug -doc -ithreads)

So I tried 'emerge -pv perl' & was told the current version of (G)Vim
required the earlier installed version of Perl.
After updating to the latest testing version of (G)Vim, I tried again :

root:522 ~> emerge -pv perl

These are the packages that would be merged, in order:

Portage is refusing to update to the latest stable Perl,
whether I have an earlier version of Vim (-13xx) or the latest version.

How do I update Perl without dropping Vim ?

It doesn't look like just vim - it looks like exiftool, graphite2,
cups-filters, gvim, and imagemagick all are blocking.

I'd guess that these packages need a version bump or you need to unmask
one of the newer builds (most likely they haven't been stabilized yet.)

Agree - my amd64 system upgraded perl to 5.22 on Friday, so re-sync, and
try again. Also to help resolve upgrade issues i firstly add --deep to
emerge's switches and if that doesnt help, bump up --backtrack=

I went through the list of conflicts and made a temporary @set of packages
for emerge to re-install. Worked like a charm. A number of the conflicts
are things that should be in a "preserved libraries" type of list, they are
actually quite able to rebuild with the new perl version.

I have, however, had to back off newest versions of sddm and chromium
(browser) due to some performance failures:  /etc/portage/package.keywords
is your friend!

Is this because you are trying to emerge perl in isolation? This result
is not unexpected as you have other packages built against the older
version and you have not told portage to deal with that.

What happens if you do emerge -uaD @world?
