skype suddenly complains about Qt

Hewson · 04-30-2008, 11:39 AM

I updated my Qt libraries and added the qt-devel packages so that I could expirement with FluxBox last week. Skype was still working fine. Yesterday I installed wine. Now Skype won't start:

Code:

[root@chives Downloads]# skype
Fatal: Cannot mix incompatible Qt libraries
Aborted
[root@chives Downloads]#

I've removed wine and re-installed the latest version of skype. still it complains.

Closed source applications like skype are linked to a specific version of a library if you are using a higher library in most cases it will not work

Thanks for the response.

skype web site just says "Qt 4.2.1+" as a requirenment.

rpm says I have version 3.3.8, and yum says there isn't a new version ?!?!

Perhaps wine required some older version of Qt and now I've gotten myslef into trouble?

any one have any ideas on what i should do to resolve this?

Did you install Skype with yum? I'm not familiar with your distro, isn't there a yum command to reinstall dependencies for a given package? You can have both QT generations installed, 3.x and 4.x.

thanks for the reply. I will look into that.
