I mentioned problems with KDE-4.14.0. At start up, Plasma-Desktop
immediately crashes and will not restart. KATE/KWrite do the same for
apparently the same reason.
Some research indicates that Qt-4.8.6 will not run on AMD-64 bit
processors. Going back to 4.8.4, which I still had on the system,
fixed the problem. I have not tried 4.8.5 yet. Has anyone used it to
know if it works or not?
Does anyone know if this had been fixed and if there is a repository
that I could download an updated version from?
While I'm running kde4-live, here's what plasma-desktop --version reports:
KDE Development Platform: 4.14.0
Plasma Desktop Shell: 4.11.11
... and uname -m:
So kde-4.14.x and qt-4.8.6 is running fine on amd64, here. =:^)
Do you have any more information on that qt-4.8.6 not running on amd64
claim? Was it qt-4.8.6 in general or only with kde? What part of qt4
(qtcore, qtwebkit, qtgui, etc) was it?
With a bit of additional information perhaps I can track down any patches
that gentoo has applied that might have fixed it for me here. But
without knowing more about what in particular I'm looking for, a quick
look at qtcore and qtgui's patches at least, says most of them were from
qt-4.8.5, tho still applied in 4.8.6. So if you jumped from 4.8.4 to
4.8.6 and found the latter didn't work, based on my patch-quick-look,
4.8.5 is likely not to work either. I didn't check in detail enough to
see if any of them were amd64 specific, however.
Which GCC did you use? IF you recall, there was a problem with 4.8.4:
https://bugs.gentoo.org/show_bug.cgi?id=450818 which was fixed. But,
something appears to have gone wrong with the new version of the
(FWIW, my qt-4.8.6 is from the gentoo/qt overlay as it hasn't made it
into the main gentoo tree yet. Neither has qt-5. They're reworking
4.8.6 and qt-5 both to cooperate better while trying to build qt-based
packages on the same system, and to use qt-chooser to select one or the
other at runtime. But that work isn't ready for the main tree yet, so
4.8.6 and 5.x both remain in the qt overlay, which I have activated and
installed them from. However, other than the occasional build
complication from generally qt4-based packages getting confused by qt5,
I've not seen any problems from it, and definitely haven't seen any
problems with 4.8.6 on amd64 -- this is the first I've read of that at
Anyway, qt-4.8.6 is definitely runnable on amd64 as I'm doing it, but
that's not saying whether there's patches applied that are allowing it,
or that it would or wouldn't break without them.
Before with 4.8.4 it was an issue of optimization so it was a compiler
issue. So, it is going to make a difference which compiler you are
using and which compiler options you use.
