[gentoo-user] qt3support issue solved

[Doug Hunley]

Just another bullet point of information for the 'can't upgrade to
4.5.2 cause of qt3support' thread. I solved it here by removing 'qt3'
from USE in make.conf. For whatever reason, I had both 'qt3' and 'qt4'
in the USE flag. Removing 'qt3' allowed 'emerge world' to do its
thing.

Is there a difference between qt and qt4?

Yes. The difference is huge.

KDE-3 uses Qt
KDE-4 uses Qt4


They are so different that a name change from Qt to something else would be 
entirely acceptable.

So for those that *had* qt in make.conf, (like me), the right thing to 
do is to change it to qt4?

I think the "qt" USE flag is deprecated in favor of "qt3" and "qt4"
USE flags and ebuilds should have been updated to use the new flags.
Use whichever one you need or want. :)

or don't use any, because they are both set as a default (for the desktop 
profile).

No, you *add* qt4 to your make.conf if you need it.

You probably still have packages that use qt3, so unless you want to unmerge 
them...

Think of it this way. Nobody in their right mind will ever get qt and gtk+ 
confused. You can have both and intermingle them, and the flags do not depend 
on each other.

Qt and Qt4 are just like that, they are that different. You cannot upgrade a 
Qt app to use Qt4 (unless you are willing to use some compat layer), just as 
you cannot upgrade a Qt app to use GTK+
