Description of problem: Qt 5.3 or programmed obsolescence? =================================== By default, Qt 5.3 is compiled by activating the use of the instructions SSE2 of the processor. References: http://lists.qt-project.org/pipermail/development/2013-November/014085.html https://lists.debian.org/debian-qt-kde/2014/07/msg00169.html The consequences: ------------------ A lot of programs do not comply any more on computers equipped with a little bit former processors, devoid of instructions SSE2. During my some tests, I have already listed sddm, AdminPanel, Baloo de KDE, Qt Creator. There is certainly the others else. Bug #13991 and #14229 Graver still: LXQt, an desktop foreseen for ligth computers, cannot work any more exactly on the computers for which it is foreseen. However, there is a possibility: Compile by clarifying not to activate SSE2. It seems that Mageia did not choose this solution. Reproducible: Steps to Reproduce:

What is the build option for remove SSE2?

I am hopeless more or less in English (Reverso translates for me). Maybe will be the answer here: https://bugreports.qt-project.org/browse/QTBUG-35430

Fedora has fixed their package to build a non-sse2 + a sse2 version. I think we should do the same

On Comment #3 (+1), just out of curiosity is that change made only for i586 arch?
(In reply to Angelo Naselli from comment #4) > On Comment #3 (+1), just out of curiosity is that change made only for i586 > arch? Yes, all x86_64 hw supports atleast SSE2
Why do we have another bugreport for this? Relevant comments are already in https://bugs.mageia.org/show_bug.cgi?id=13991 This is the third bugreport for the same issue, I've already closed Bug 14491 due to this. *** This bug has been marked as a duplicate of bug 13991 ***

I was able to redo the tests on my old machine. I want just to confirm that the recompilation of qtbase5 by doktor5000 solved several problems.
