Symlink of qt4 (although blacklisted) have been deleted on slackware64-current

Hi,

I use luckybackup, so I have qt4 installed
I've noticed (I don't really know exactly which upgrade) that all the symlinks have been removed from /usr/lib64 & /usr/lib64/qt/lib/ although I have blacklisted qt-4.* in /etc/slackpkg/blacklist

is the presence of qt4 a problem ?
And so, Should I avoid using it ?
Knowing I can do without it

My question is: is this normal for technical reasons, in which case we close the debate :-)

Is the package qt- there in /var/log/packages ?
If not your blacklist command was not applied correctly. Maybe because of a wrong syntax.

In this case do a installpkg qt-.... from your old qt4 package.

Else I don't see why some symlinks disappeared.

If you wan't a sbo like version of qt4 which can be compiled with the latest Slackware current, mine is here :
https://github.com/BrunoLafleur/pbsl.../kde4/other/qt
https://github.com/BrunoLafleur/pbsl...other/qtwebkit

The original qt package has been split in the two packages above for better respect of sbo rules.

Yes. but I reinstalled it

Here is my blacklist :

Code:

root:~/ # grep qt- /etc/slackpkg/blacklist
qt-4.*

Works well and was not removed, if a do a slackpkg clean-system

Yes, I did that.

But it's ok for me.
Once I notice symlink have disapeared, I just have to reinstall the pkg
It doesn't take that long :-)

Were the symlinks ones that exist on the qt5 package? If so, any upgrade of qt5 will overwrite the symlinks from qt4 unless you make them immutable (chattr +i /location/to/symlink).

qt4 has all libs in /usr/lib64/qt/lib
qt5 has them in /usr/lib64 and /usr/lib64/qt5

So there should not have conflicts between them.

I confirm this :

Code:

EDIT : I re-opened this thread, I didn't think anyone was finally going to look into the subject :-)
