[gentoo-user] qt USE flags conflict

[gentoo-user] qt USE flags conflict

[-- Attachment #1: Type: Text/Plain, Size: 2356 bytes --]

On a no-multilib machine I have arrived on a circular argument:
==============================================================
# emerge -uaDv world

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

Calculating dependencies... done!

390_32(-)?,abi_s390_64(-)?]".
!!! One of the following packages is required to complete your request:
- dev-qt/qtcore-4.8.6-r2::gentoo (Change USE: +qt3support)
- dev-qt/qtgui-4.8.6-r4::gentoo (Change USE: -qt3support)
(dependency required by "dev-qt/qtgui-4.8.6-r4::gentoo" [ebuild])
(dependency required by "app-text/poppler-0.32.0::gentoo[qt4]" [installed])

plugins/evas_generic_loaders-1.12.0::gentoo[pdf]" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])
==============================================================

Fair enough, I add qt3support for dev-qt/qtcore-4.8.6-r2 and remove it for 
dev-qt/qtgui-4.8.6-r4, then rinse and repeat:
==============================================================
# emerge -uaDv world

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

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy "~dev-

I don't want to bore you, but you can guess that if I were to reverse these 
USE settings I will arrive at the previous message.  How to proceed from here?

I had this myself a while back. Add or remove the flag to BOTH packages.

Look carefully at the first message again, it says you need to do one of
those actions (effectively making one package match the other). A quick
glance can seem like it wants you to make the USE settings different,
that is not the case.

Yes!  I removed all USE flags for qt packages, then set +qt3support for both 
of the above complainers and some more that portage told me to and hey presto 
it is now updating all relevant qt packages to the latest version.

Thanks once more Alan!  :-)
