 Posted: Mon Nov 06, 2017 8:39 pm Post subject: KDE Applications 17.12 allow full qt4/kde4 removal?SOLVED |
 |
|
With the upcoming (Dec 14,2017) KDE Applications 17.12 and associated Plasma/Frameworks updates, are we at long last going to be able to remove qt4 and kdelibs-4, etc., and the associated USE flags?
Any info and/or links to such info are greatly appreciated. Guess there may be a few apps still not ported to qt5, but it must at this point be getting down to a very few that still require qt4.

With KDE Applications 17.12 there are only associated Applications updates. There are no kdelibs-4/qt4 dependencies for Plasma or Frameworks anyway, except for Qt4 integration convenience.
17.12 will not have any kdelibs-4 depending packages. See also https://community.kde.org/Applications/17.12_repo_drop_list_kdelibs4
However, you can have that today:
| Code: | $ find kde-apps/ -name "*meta*17.08*ebuild" -exec grep -H IUSE.*qt4 {} \;
kde-apps/kde-apps-meta/kde-apps-meta-17.08.2.ebuild:IUSE="accessibility pim +qt4 sdk"
kde-apps/kdenetwork-meta/kdenetwork-meta-17.08.2.ebuild:IUSE="nls ppp +qt4"
kde-apps/kdeutils-meta/kdeutils-meta-17.08.2.ebuild:IUSE="cups floppy lirc nls +qt4"
kde-apps/kdemultimedia-meta/kdemultimedia-meta-17.08.2.ebuild:IUSE="+cdrom +ffmpeg nls +qt4"
kde-apps/kdeaccessibility-meta/kdeaccessibility-meta-17.08.2.ebuild:IUSE="nls +qt4"
kde-apps/kdegames-meta/kdegames-meta-17.08.2.ebuild:IUSE="nls opengl python +qt4" |
That doesn't cover non kde-*/* packages though. |

| kdelibs4 will probably go away, qt4 will take forever to get rid of. Too many non-kde things still use it and have no replacement (e.g. mumble). |

asturm & Ant P.,
Thanks much for the info and link,
Not sure I'm understanding correctly. I guess I was asking at what point can we remove qt3support qt4 from our USE flags, and be done with qt4 and kde4? Why would we still need or want Qt4 integration convenience, much less any qt3support, unless we really wanted to run old applications that needed it?
If I run equery d qtcore-4.8.7 it returns ALL my up-to-date ~arch qt-5.9.2 and current kf5 packages as dependent. 
Assuming I didn't have or want any packages requiring such support, what would happen if one just removed both qt3support qt4 global USE flags and ran an emerge -uDN @world on a current ~amd64 qtkde system? Disaster, or basically nothing except no more qt4 kde4 cruft?

That's a sure sign that the output is wrong, no?

Works fine for ~arch kde-*/* packages, but purely depends on the other applications you have installed - but didn't I tell that already? |

OK, I just looked at this, and it doesn't look intimidating at all:
| Code: | gentoo-main # USE="-qt3support -qt4" emerge -uDNvp1 @world
These are the packages that would be merged, in order:

If there were any potential serious consequences, wouldn't emerge issue warnings and refuse to go on if anything I have installed still required qt3support and qt4?

It means you haven't installed stuff that was determined to hard-depend on qt3support/qt4. Rather, you haven't installed that much at all, which makes this easy.
However, please read your news items. |

Thanks asturm.
I do have all of kf5 stuff and pulled in qt5, except no kde games or kmail stuff, so it's basically a full-fledged kde system.
Guess I'll go ahead and try removing qt3support and qt4, do the emerge -DN1 @world, then do my regular depclean -pv and see what shows up.
UPDATE: All 12 packages on the -DN1 @world emerged fine (as expected), then I depcleaned all the qt4 and kde4 stuff which was now consigned to the "cruft" category.
At first, emerge @preserved-rebuild wanted to reinstall a few core kde4 and qt4 and related packages, but after a careful depclean it gave up, and revdep-rebuild says system is all consistent. A reboot and several hours running a pure kf5 system seems to confirm it.  ( at least for an ~amd64 kde system with everything but the games and kmail related friends)
No problems. Guess as asturm says, it depends on what you have installed. In my case it was a breeze.

FWIW, on another gentoo ~amd64 full kde box (1279 installed packages) I ran into some complex problems with something insisting on pulling in many qt4 and kde4 packages. Couldn't run depclean and had to spend time sorting out various reasons that could be so stubborn. Finally realized it was libreoffice pulling in qt4/kde4 and had to remove it. Then I could finally run a full emerge -DN @world and complete a depclean which removed 63 packages (included some old long forgotten stuff (mostly deps) that had accumulated on this 2-3 year old install). Revdep-rebuild then reported system consistent.
When I tried to re-emerge libreoffice, it wanted to pull in a massive qt4/kde4 and lots of other packages (64 in all). Even libreoffice-bin wanted qt4 flags on several packages. Apparently, libreoffice isn't qt5 friendly yet, so I'm looking at Calligra for a temporary replacement. I'm concluding that most likely unless you run a pretty lean system, removing all qt4 and kde4 items will present a few problems.

That happens only if you emerge Libreoffice with USE flag 'kde'. Try the command below:
| Code: | | USE="gtk -gtk3 -gnome -kde" emerge -pv libreoffice |

FYI i removed qt4 and kde4 apps from my desktop a few weeks ago :
- https://forums.gentoo.org/viewtopic-p-8132302.html#8132302
- https://forums.gentoo.org/viewtopic-p-8133812.html#8133812
To sum up :
- i added -qt4 in /etc/portage/make.conf
- i upgraded a few apps to ~arch to use qt5 instead of qt4 : hplip
- i disabled kde useflag for libreoffice-bin
- i manually uninstalled some ebuilds like kde-apps/kdebase-data or kde-apps/kdebase-kioslaves
=> i guess these packages were added to my world file after re-emerging them without the --oneshot option in the past
- I masked qt4 ebuilds
- i installed a qt-5 version of clementine (see bugs.gentoo.org) and removed one ebuild (unetbootin). |

For the moment I need qt4 for qgis, with version 3 I can switch to full qt5

If I try USE="-qt3support -qt4" emerge world -uDNpv I get some blockers.

Does that mean that I still need qt3support and qt4 and cannot yes switch to system without those two useflags ?

Existing applications prevent you from doing that.

You can't (easily) do that on a stable system. |

| I just removed qt4, kdelibs, and qt3support here on my ~amd64 kde-apps/kde-apps-meta install. It wasn't that bad at all. Just watch for libreoffice as stated as well as vlc (-kde). Also check the handbook use flag as it seems to pull in qt4. |
