[gentoo-user] Removing qt4 meta

[gentoo-user] Removing qt4 meta

[Marco]

Hi all,

some time ago I installed qt4 for testing. Now, after I run 'emerge
--sync' and 'emerge --update world --pretend --verbose' I get a
message that the qt4 meta ebuild is hard masked and that the meta
ebuild should not be used anymore in the future. How can I remove all
the packages in the meta package? 'emerge --unmerge qt' only removes
x11-libs/qt but not the dependencies/meta ebuild....

Thanks for your help!

Best regards,
 Marco

No need to do that. It's about the meta package only.

That's correct, x11-libs/qt _is_ the meta ebuild.

You may need to re-install a couple of packages which depend on it their 
installed version, but have their deps corrected in the portage tree. For me, 
those where avahi and qimageblitz.

Just in case I would want to remove all the packages, how could I do
that? (I'm not doing any qt develoment anyway and I take care not to
install any software that depends on qt)

How to do that? Is 'emerge --update --newuse --deep world' enough?

If you have eix installed you could use
eix -I --only-names x11-libs/qt |xargs emerge -C

or if you have no package that depends on qt
emerge --depclean -a
after emerge -C x11-libs/qt
should do the job.

You should do
emerge -DuNva world and revdep-rebuild
afterwards to be sure the system is still in clean state.

Is there a way to find out if packages depend on qt? Although I think
I did not install any packages that depend on qt (saving space) I am
not 100% sure...

Well, paludis said it couldn't uninstall it because there were packages 
depending on it (don't know what emerge does in this case since I didn't use 
it for a very long time now). Those packages should be reinstalled first. 
revdep-rebuild doesn't work here.

equery depends <package_name>

Note that this lists packages that *could* depend on the named package, not 
just those that *do* depend on your specific machine.

also look at qdepends -d

Hi all,

thanks for all your tips! Also found some inconsistencies in my
installation, which I was able to fix.

emerge --depclean -pv qt-core
