[gentoo-user] Qt blocking @world update

[gentoo-user] Qt blocking @world update

[Alex Schuster]

Hi there!

My @world update did not go well. It was much worse some while ago, so I
just did an emerge -e @world, after manually removing stuff
from /var/lib/portage/world until I got no complaints any more. I had to
remove kde-misc/publictransport and kde-misc/plasma-emergelog for that.

After most was done, it stopped after one package failed to build, and
was unable to resume due to blockers. emerge --resume gives this:

weird portage # emerge -aj --resume

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

Calculating dependencies... done!

Wow, I don't even... anyway, I thought emerge -DuN @world might work now, but
it does not, again due to Qt problems. And those I do not understand:

    (and 1 more with the same problems)

So, 4.8.4 and 4.8.5 are somehow both needed. Let's start at the top: fsrunner
and kdid3 need >=dev-qt/qtgui-4.7.4, which 4.8.5 also would satisfy, but one
needs ~dev-qt/qtgui-4.8.4, and that is dev-qt/qt3support-4.8.4. What needs that?

The 2nd entry from the bottom states that ~dev-qt/qt3support-4.8.4 is required
by dev-qt/qtgui-4.8.4-r1.

The output also says 'and 1 more with the same problems' - might this be the
real reason? How would I find out what package this is? The --tree output only
shows fsrunner pulling in qtgui-4.8.4:

[nomerge       ] kde-misc/fsrunner-0.7.5:4::kde  USE="(-aqua) -debug" 
[nomerge       ]  dev-qt/qtgui-4.8.4-r1:4 [4.8.5-r1:4] USE="accessibility cups dbus%* exceptions gif%* glib gtkstyle mng nas pch qt3support tiff xinerama xv (-aqua) -c++0x% -debug -egl -nis -trace"

[ebuild     UD ]    dev-qt/qtgui-4.8.4-r1:4 [4.8.5-r1:4] USE="accessibility cups dbus%* exceptions gif%* glib gtkstyle mng nas pch qt3support tiff xinerama xv (-aqua) -c++0x% -debug -egl -nis -trace" 0 kB
[ebuild     UD ]     dev-qt/qtdbus-4.8.4:4 [4.8.5:4] USE="exceptions pch
(-aqua) -c++0x% -debug" 0 kB

The ebuilds for fsrunner and kdid3 only have the 'interit kde4-base' line, no
special dependencies.

Any enlightenment would be very much appreciated. I just don't know how to get
my system back working. ATM, KDE is mostly at version 4.11.2-r1, but some KDE
packages still need to be updated. So, it does not work right now, unknown
protocol file and such errors.

  Let's start at the top, as the python errors may cascade and cause
other errors.  From that output, it looks like you do not have any
version of "python_single_targetX_Y" enabled.  That could be your
problem right there.  What python settings do you have in make.conf?  I
have 3 lines.

PYTHON_SINGLE_TARGET="python2_7"
PYTHON_TARGETS="python2_7"
USE_PYTHON="2.7"

Also what do you get when you type "eselect python list"?  In my case I get

[i660][waltdnes][~] eselect python list
Available Python interpreters:
  [1]   python2.7 *
  [2]   python3.2

Re: [gentoo-user] Qt blocking @world update

[Alan McKinnon]

Excuse the top-posting; if I try inter-post between all those blockers
you'll never find what I reply :-)

First I recommend to sync your tree again, just in case you got yours
between two Qt commits and things are not consistent anymore.

You seem to have at least two things happening:

python-exec
qt

To deal with the first, try remove python-exec and re-merge it (but
quickpkg a backup first)

quickpkg python-exec && emerge -avC python-exec && emerge -av1 python-exec

This is untested so I don't know if it will bork. If it does, you have a
quickpkg that you can untar and get things back.

Onto Qt:

I've had similar things over the years and it always made little sense.
Eventually I removed all references to Qt from world, sets in use and
USE then let portage figure out what to do. Rationale: Qt is a basic
toolkit that stuff uses, so stuff should decide what it needs and not
me. I want the stuff and if that requires Qt then just let portage give
me what is required.

This will show all references to Qt to consider:

grep -ir /qt /etc/portage/ /var/lib/portage/world*


In your case, I see portage wants to downgrade several Qt packages due
to fsrunner, but there's nothing in that ebuild or the kde4-base eclass
it inherits, which leads me to believe you might have a config setting
somewhere that wants to exclude latest Qt somehow. Portage and the tree
by itself isn't doing it, here's my output:

$ emerge -pvt fsrunner

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

Calculating dependencies... done!
[ebuild  N     ] kde-misc/fsrunner-0.7.5:4  USE="(-aqua) -debug" 18 kB

Total: 1 package (1 new), Size of downloads: 18 kB

I only have PYTHON_TARGETS="python2_7", but commented. Don't remember
when or why I did this. Bit it is set per default, emerge --info gives:
  PYTHON_SINGLE_TARGET="python2_7"
  PYTHON_TARGETS="python2_7 python3_2"
  USE_PYTHON is unset

AFAIK PYTHON_TARGETS defines for which versions of python you build
packages. And in case a package only allows to be built for a single
version of portage, this is set with PYTHON_SINGLE_TARGET. But what does
USE_PYTHON do? Is it documented anywhere? I don't find it in the man
pages of make.conf, portage or emerge.

  [4]   python3.3

So, all looks fine to me. USE_PYTHON=2.7 emerge --resume gives the same
error.

But then I upgraded python-exec. This went without problems, and now the
python errors are gone, and I only get this:

 * One or more packages are either masked or have missing dependencies:
 * 
 *   >=dev-libs/icu-3.8.1-r1:0/51.1= pulled in by:
 *     (net-libs/webkit-gtk-1.10.2-r300::gentoo, installed)
 * 
 *   ~app-emulation/emul-linux-x86-medialibs-20130224 pulled in by:
 *     (app-emulation/emul-linux-x86-qtlibs-20130224::gentoo, installed)

Hmm. I have icu-51.2 installed, and emerge -u icu would happily upgrade to
51.2-r1. But with -deep I get app-emulation/emul-linux-x86 blockers
(xlibs, baselibs, opengl). Well, I'd say let's skip this. The failed
emerge -e was days ago, the portage tree has changed, my interest is not
so much continuing this failed emerge, but being able to update @world
again.

Thanks for responding Walt!

I would, but for everyone else it's a mess. E-mail with line breaks is
not suited for this kind of output.

Ah, I have this problem for weeks now, but did not care enough. And did
not have the time for this.

Thanks, a simple upgrade just worked, as I wrote in the reply to Walt.

I commented them all out, I still get the error about multiple Qt
versions.

Same here, except that it's emerged already.

OK, I have no clue how to further debug this. But what I did is:

for (( i=500; i > 0; i-=20 ))
do
   emerge -DautvNj $( head -n $i /var/lib/portage/world )
done

This failed until $i was 260, so I tried a little more, and removed 
media-sound/kid3 from @world. Along with fsrunner of course. Now, it's 
building.

This does not make any sense, does it?

Actually, it does make sense, in a weird kind of way

kid3 and fsrunner are not part of KDE proper (i.e. they are not shipped
in the huge KDE tarballs). So they may be inconsistent with the main
release due to no QA checks beyond what the dev does. And I doubt the
gentoo KDE team checks such packages before updating ebuilds.

I would use this approach:

Remove from world every KDE package that is not in kde-base (quickpkg
first to make restores easier), then update world and do a depclean.
Chances are very good it will complete cleanly.

Then emerge all those KDE packages back in using the -t option to emerge
and see what is causing issues.

I think the odds are very good you will find an out-of-sync package that
directly DEPENDS on some old version of Qt (or something equally silly).
That package might even already be in the emerge output, but buried in
the voluminous output portage gives these days

I, too, had been having qt blocking qt, and I had no idea what was
causing it. I guess I caused it myself because I updated qt with
--nodeps (long story, kde 4.11.2 needs akonadi-server 1.10.3 which
needed the then keyworded qt 4.8.5).

Both 4.8.4 and 4.8.5 were stable by the end, but still something caused
to pull in both, just as in your output. Yesterday I wanted to clean up
emerge output so I can ask about it here. So I updated everything except
qt (without --nodeps). And now world update is clean again.

But what exactly is it that pulls in the older Qt?

Well, I was at this point already, after excluding fsrunner and kid3.

emerge fsrunner would happily just install fsrunner, but emerge -Dpu
fsrunner again wants to downgrade Qt to 4.8.4. The same goes for kid3.

No big deal, I don't really need those.

But emerge -uD @world no longer complains.

Of course I have other problems now... but I will start a new thread for
that.
