Description Sandro Mani 2016-04-14 21:56:47 UTC 
Description of problem:
Any version after qt-4.8.7-6.fc24 fails to load plugins. Most noticeable because the application fails to load the style plugins. Other applications, such as qpdfview, are unusable because they can't load the necessary plugins.

Suspect an issue related to GCC6, i.e. qt = 4.8.7-6.fc24 is the version before the GCC6 mass rebuild.

Version-Release number of selected component (if applicable):
qt > 4.8.7-6.fc24

How reproducible:
Always
Comment 1 Rex Dieter 2016-04-15 02:35:42 UTC 
OK, I found this:

Comment 2 Rex Dieter 2016-04-15 02:44:00 UTC 
rebuilding qpdfview fixes it, though I'll need to verify what we really want for build key here.
Comment 3 Kevin Kofler 2016-04-15 10:26:32 UTC 
There is already a patch to support GCC 5 for the build key, we just need to fix it to support >5, too. I think that when I did that patch, I did not realize that GCC was not going to stay on 5.x.x for long, I was expecting 5.x.x to last at least as long as 4.x.x did. But GCC has joined the Chromium/Firefox version race now. :-(
Comment 4 Kevin Kofler 2016-04-15 10:26:59 UTC 
(The build key should be g++-4 for any GCC >= 4.)
Comment 5 Rex Dieter 2016-04-15 12:08:20 UTC 
Yeah, I think I can confirm the buildkey is borked, which means :

1.  fixing qt
2.  rebuilding everything that had been built against the bad/tainted qt

:(

Comment 7 Kevin Kofler 2016-04-15 12:32:59 UTC 
Yes, sadly, that's what it amounts to. :-(

Looks like we do not carry a patch to fix the build key in Qt 4 anymore, we're now using what upstream ships and that's broken. Grrr… Thanks for the fix!
Comment 8 Rex Dieter 2016-04-15 12:45:51 UTC 
Kevin, instead of rebuilding everything, do you think we could perhaps limit it to only packages that provide plugins (ie, include anything that matches */*.so)?

Comment 10 Fedora Blocker Bugs Application 2016-04-15 17:57:24 UTC 
Proposed as a Blocker and Freeze Exception for 24-beta by Fedora user rdieter using the blocker tracking app because:

 Building Qt (4) with gcc6 inadvertantly changed it's internal BUILD_KEY used to enforce loading/compatibility with loading plugins.  As a result, all Qt4 applications built after the initial f24 mass rebuild that use or include plugins can fail to run properly.

I've filed https://fedorahosted.org/rel-eng/ticket/6392 for rel-eng assistance to 1. identify affected packages and 2. perform mini-mass rebuild(s) as needed

Comment 24 Kamil Páral 2016-04-18 16:46:24 UTC 
Discussed at today's blocker review meeting [1]. Voted as RejectedBlocker (Beta) AcceptedBlocker (Final) AcceptedFreezeException (Beta) - does not violate any of the Beta criteria, but does violate "All applications that can be launched using the standard graphical mechanism of a release-blocking desktop after a default installation of that desktop must start successfully..." in the case of qt4 apps installed with the KDE spin. It as accepted as a Beta FE for this reason.

Hi,

Sorry, not solved for amarok. Still same error.


Martin Kho
Comment 45 Sandro Mani 2016-04-20 09:42:20 UTC 
I suppose Amarok (and other like qpdfview, qgis, ...) also need to be rebuilt?
Comment 46 Rex Dieter 2016-04-20 14:46:07 UTC 
arg, seems at least some of these latest rebuilds set the wrong buildkey too.

some examples for comparison:

$ rpm -q phonon
phonon-4.8.3-11.fc24.x86_64

$ strings /usr/lib64/qt4/plugins/designer/libphononwidgets.so | grep buildkey
buildkey=g++-4 x86_64 linux g++-4 full-config


$ rpm -q tomahawk
tomahawk-0.8.4-9.fc24.x86_64
