Description Matěj Cepl 2017-03-06 14:57:39 UTC

Description of problem:
LyX 2.2 includes some significant improvements (http://wiki.lyx.org/LyX/NewInLyX22).

Rawhide package builds in epel-7 buildroot https://koji.fedoraproject.org/koji/taskinfo?taskID=18221553

Comment 1 Rex Dieter 2017-03-06 15:00:10 UTC

Discussed on irc a bit, and think the best short-term plan would be to do a epel-7 lyx-2.2 update, but using qt4 instead (means less churn compared to existing lyx-2.1 available in epel7).

José, how does that sound to you?

Comment 2 Fedora Update System 2017-03-06 16:31:04 UTC

lyx-2.2.2-5.el7 has been submitted as an update to Fedora EPEL 7. https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2017-0395758b2b

That seems a good plan. :-)

While testing 2.2 for Fedora I have tested both qt4 and qt5.
And since that it is still supported upstream (it is both developed and tested) it is a safe choice.

In terms of the spec it should be probably enough to play with with the

%global use_qt5 1

and make it conditional. I tried my best to leave that option open.


FWIW I have been building packages based on qt5 for EPEL:

My previous comment was sent before seeing this. :-)

Well done.

Comment 5 Rex Dieter 2017-03-06 16:49:28 UTC

Thanks, are you aware of any qt4 or qt5 specific issues or any advantages/disadvantages to either?

If nothing significant, we probably can consider using Qt5 unconditionally at some point in the future.

IMHO after reading the development mailing list the advantage seems to be with qt5 since it is being continuously developed and improved.

After all we are at qt 5.7 while qt4 was at 4.8, so more or less the same number of iterations. I am aware that this is an anecdotal evidence due to the evolution of the development style for qt but the main idea stands. :-)

On a more objective note there issues that happen with qt4 that do not happen with qt5, IIRC the cache of figures is one of them, due to internal improvements in qt.

I agree, if I had to choose a qt versions that tips the balance I would say that with qt 5.6 qt5 definitively surpasses qt4 (at least for lyx).
