I killed Amarok [Solved]

[Lucidor]

Being music enthusiast, I updated to a new version of FLAC that was available in portage. Now, when I start Amarok (or actually amarokapp) I get the following error:

amarokapp: symbol lookup error: /usr/lib/libamarok.so.0: undefined symbol: _ZN9QGLWidget16setMouseTrackingEb

It used to run just fine! Silly me, why did I upgrade. A quick Google did not give anything substantial on the matter. And revdep-rebuild has no objection to my system.

Ideas? Should I downgrade FLAC? I'm not even sure to which version.

The one my system (flac unchanged, sab 3.4a) is 1.1.2, if that helps any. try emerge -c flac then emerge 1.1.2.

Do any of your other media apps work (e.g. Kaffeine)?

EDIT: Ok, I just updated FLAC to the latest (1.1.4), and at the end this message was displayed:

* Messages for package media-libs/flac-1.1.4:

* If you've upgraded from a previous version of flac, you may need to re-emerge
* packages that linked against flac by running revdep-rebuild

Have you tried running revdep-rebuild like it suggests?

lol.

My revdep-rebuild did compile a few packages after the FLAC upgrade and as mentioned earlier, was happy after.

I found a report in an Arch forum on identical problems with Amarok as I experience. There seem to be a strong dependance on QT version, so I updated that and now I'm in a seemingly infinite loop of new dependency-enforced updates. As my computer is not the fastest, it has been compiling for close to 24 hours now. Every now and then, emerge stops and tells me that some library needs to be recompiled with some additional use flag. So it goes on. Looks like I'll have a complete update world when (and if) I'm done!

BlueJayofEvil, did you tried Amarok after the FLAC update? Does it run?

[Lucidor]

It eventually finished compiling (after 24 hours!) and it was still possible to reboot and everything looked fine, except that Amarok still didn't start. In a final attempt I reinstalled Amarok, and much to my surprise, it ran just fine!

I'm amazed that this dependancy hell could actually be sorted by reading the information from emerge and following it's guidance. I was on the verge of wiping the whole system clean with a fresh install when suddenly all parts fell into place. I still need to play around a bit to ensure that nothing else got broken in the process, but it looks very promising.

Just a warning about the latest version of FLAC (I also posted this in my thread about my Sound Juicer problem):

The API underwent fundamental changes in the version 1.1.3 which break the compilation of all existing players using libFLAC. Nobody knows how fast developers can or will adapt to these changes.

Link to quote

So until audio programs are updated to support FLAC 1.1.3 and later, avoid upgrading if possible. Sabayon comes with 1.1.2, which is the version before the major change.
