Re: WARNING: Opera likely broken by today's qt update!

There's no need to downgrade qt and break other installed applications. Even though opera is binary only. You can just supply opera with what it needs using LD_PRELOAD. We'll just copy the 4.5.2 versions of libQtCore and libQtGui from the old package to /usr/lib/opera/10.00 and tell opera to use those instead of the installed 4.5.3 libs:

$ mkdir scratch
$ cd scratch
$ cp /var/cache/pacman/pkg/qt-4.5.2-7-i686.pkg.tar.gz .
$ tar vxzf qt-4.5.2-7-i686.pkg.tar.gz
$ su 
# cp usr/lib/libQtCore.so.4.5.2 /usr/lib/opera/10.00/
# cp usr/lib/libQtGui.so.4.5.2 /usr/lib/opera/10.00/

Edit opera's launcher script (/usr/bin/opera) and change the last "exec" line with these two lines:

LD_PRELOAD=/usr/lib/opera/10.00/libQtCore.so.4.5.2:/usr/lib/opera/10.00/libQtGui.so.4.5.2 ${OPERA_BINARYDIR}opera "$@" &
disown

Then run opera as usual, and confirm:

# lsof | grep libQtGui
kdeinit4   4749 chenno  mem       REG        8,2  9955448     871586 /usr/lib/libQtGui.so.4.5.3
klauncher  4750 chenno  mem       REG        8,2  9955448     871586 /usr/lib/libQtGui.so.4.5.3
kded4      4753 chenno  mem       REG        8,2  9955448     871586 /usr/lib/libQtGui.so.4.5.3
opera      5221 chenno  mem       REG        8,2  9958648     100559 /usr/lib/opera/10.0/libQtGui.so.4.5.2

KDE still uses qt 4.5.3, only opera now uses 4.5.2. I've opened >10 tabs, including flash vids and the acid test, no problems.

Build a package with ABS that does this if you want to keep your system clean (pacman doesn't know about the 4.5.2 libs in /usr/lib/opera if you do the above)

Anyways, it's much better than downgrading all of qt and risk other things to break. It's ugly, of course,  but then binary only programs are ugly to begin with

Re: WARNING: Opera likely broken by today's qt update!

well its more a workaround than a real patch heheh

but hey, if u create the package tell it here pls.

btw: chromium is fitting nicely on kde (which is a bit strange for a gtk app)

Re: WARNING: Opera likely broken by today's qt update!

I confirm that this works fine, for the time being anyway.
Though it gave me a little scare as i did a pacman -Syu on the side & after the above changes opera started working & mplayer-svn broke! but it was due to some other upgrade (don't remember now which package it was 4 A.M.) & gave
"mplayer: error while loading shared libraries: libaudio.so.2: cannot open shared object file: No such file or directory"
A simple recompile fixed this.
Now i am Happy Happy Happy!
He he.

Thanks hbekel

Re: WARNING: Opera likely broken by today's qt update!

Does someone know when the fixed version of Qt (especially qtmod) will be available in pacman repositories?

BTW Workaround presented a few posts above does not work for me. I think it's because I use qtmod (from KDEmod project) and when I tried to run Opera with those two libraries replaced (taken from 'normal' Qt, not qtmod) it crashed with the message like "Mixing incompatible versions of Qt is not allowed!". Does anybody have a package qtmod in version 4.5.2?

Is it a Qt issue or an Opera issue...

Re: WARNING: Opera likely broken by today's qt update!

Finally, the new QT-updates fixed the problem for me today.
I am surfing about one hour with opera and i had no problems so far.

Yes! I am relieved. ( I hate Firefox ^^ )

Edit: DOH! Bug still exists but does not appear frequently ...

Re: WARNING: Opera likely broken by today's qt update!

If you read the latest comments, you should find help there: http://aur.archlinux.org/packages.php?ID=15228

You have to build the latest opera-snapshot (version in aur is not up to date). You can use the opera-devel-qt4 PKGBUILD and change the version-number, there is also a PKGBUILD posted in the comments.

I also did this:

for workaround opera stuck problem (opera 10.01 , Qt 4.5.3 , slackware 13):
disable "Synchronous decode" in opera:config
works for me

So I don't know what really helped. Probably it helps to just change this option and you don't have to upgrade to the snapshot then.

Sweet, thanks -- this worked for me as well. I did both of the above steps.

Re: WARNING: Opera likely broken by today's qt update!

using opera-beta and modify the version to 4694, this works good for me. Since developer post on their blog that this should work with the newest qt.

Re: WARNING: Opera likely broken by today's qt update!

Yes, after a little testing I found out that it is not necessary to change the "Synchronous decode" option if you use the newest build. But perhaps it helps with the stable version? (Didn't check this)

The development version is quite stable anyway. Btw: You don't need to change the version to 4694 anymore, the package was updated.

Re: WARNING: Opera likely broken by today's qt update!

from my experiments on a fairly vanilla arch64 install, the freezing pages issue happens with static builds, and not shared builds. I assume that's because of some Qt multithreaded weirdness?

rc-4720 is released, and the G4 builds look fine.

Re: WARNING: Opera likely broken by today's qt update!

I can confirm that disabling 'Synchronous decode' works. At least it did for me.
