qt library

[starangyl]

I have a major problem now. When i run vlc, nothing shows up so i went and ran vlc from the terminal. It ssaid that i had two incompatible QT libraries. THIs might be becaause i have qt3 AND qt4 installed (kde3 and kde4 respectively), but how do i fix it?

What distribution are you using etc.?

Arite.

I'm getting it too:

Code: Select all

[00000001] main libvlc debug: translation test: code is "C" [00000001] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. Cannot mix incompatible Qt libraries Aborted

This is running under Ubuntu 8.10. I've tried upgrading to 0.9.8 but I still get it. I haven't used it for a few weeks so I'm not sure if an update or something I installed broke it.
Here's a listing of what QT libs/apps I have installed.

i'm using ubuntu 8.10

it seems that qt4 and qt3 clash and render vlc inoperatable.

and yes, vlc upgrade killed it. my old vlc (before upgrade) didn't have any problems. according to the log, the new one pulled the qt4 libraries in and therefore killed itself.

I have VLC 0.9 and 1.0 (on Qt4.4) running inside KDE3.5 (on Qt3.3) with no problems.

This crash means you are trying to load different versions of Qt within the same process. Remove whatever is causing VLC to load Qt3 (VLC itself does not do this in any version).

Same problem here, Ubuntu 8.10, KDE 4.2. Was working fine this morning before I did an apt-get upgrade. Purging and reinstalling vlc didn't fix it.

What other processes should we look for?

Thanks

[agroz]

Fixed it.

Go into your ~/.config folder and mv the Trolltech.conf file to Trolltech.conf.broken or some such. Then VLC starts fine.

Not sure why it works but it does...

thanks buddy

fixed it and worked like a charm !

what is in Trolltech.conf anyways...

[agroz]

You're welcome. I actually found that fix by googling for a similar error; the fix was something that worked for Firefox last year for some users.

Not sure what's with the Qt config file. I did a diff on the two versions and the output is huge; but obviously something changed in the way the qt libs are loaded.

I'm not savvy enough to get past that point, unfortunately.

The only problem with your post is that it only works until you restart your system.

We need a more permanent solution.

And for those "admins?" who didn't respect the thread, the issue is 100% with videolan. Also, you haven't updated this program for Linux in some time. Please do so.

[Jean-Baptiste Kempf]

No, the issue is with your configuration of Qt.

No, the issue is entirely with your distribution where either Qt3 and Qt4 packages are not correctly configured and built, or with the distro packager of the vlc version you used who has been unable to link vlc properly to the Qt4 libraries.
As an example, I run VLC 0.9.8a on Slackware with both Qt3 and Qt4 libraries installed, one system has KDE 3.5.10 and the other has KDE 4.2 and on both computers I have zero problems.

Also, you haven't updated this program for Linux in some time. Please do so.

What are you talking about? The most recent official release (0.9.8a) is a little over two months old. You consider that a long time ago?
Perhaps your distro does not offer a recent version of VLC, but that is not the vlc delopers' fault.

Complain to your broken distribution.

And for those "admins?" who didn't respect the thread, the issue is 100% with videolan. Also, you haven't updated this program for Linux in some time. Please do so.

Again, complain to your distro for not updating the package. The VideoLAN project cannot do the job of distributions.
