I'm running a Slackware 9.1 system here (well, it started out that way), and I decided to upgrade KDE a little. So I grabbed...

kdelibs-3.5.1-i486-1
kdebase-3.5.1-i486-1
qt-3.3.5-i486-1

...from slackware-current and ran upgradepkg. So far, so good. But when I try to run something like konqueror, I get messages complaining about...

Could not find start_launcher: /opt/kde/lib/kde3/klauncher.so: undefined symbol: start_launcher
kdeinit: Communication error with launcher. Exiting!
---------------------------------
It looks like dcopserver is already running. If you are sure
that it is not already running, remove /home/greg/.DCOPserver_greg__0
and start dcopserver again.
---------------------------------


...and konqueror doesn't start. If I try k3b, I get messages like...


k3b: Symbol `_ZTI18KUniqueApplication' has different size in shared object, consider re-linking
k3b: Symbol `_ZTI9KComboBox' has different size in shared object, consider re-linking
k3b: Symbol `_ZTIN6KParts14DockMainWindowE' has different size in shared object, consider re-linking
k3b: Symbol `_ZTI11KMainWindow' has different size in shared object, consider re-linking

Could not find start_launcher: /opt/kde/lib/kde3/klauncher.so: undefined symbol: start_launcher
kdeinit: Communication error with launcher. Exiting!


...but at least it starts after brining up lots of little dialog boxes complaining about malformed URLs. But it doesn't work. So I must have something missing or out of sync, but I'm not sure which part that is. FWIW, here's the output of 'ldd /opt/kde/lib/kde3/klauncher.so'

(P.S. I don't use KDE as my desktop, I just want to run programs like k3b.)

slack 9.1 runs kde 3.14......that's a huge jump to 3.5x
you'll need to read the changelogs that pat has posted to see what packages/libraries will need to be upgraded so 3.5x will work properly!!

Looks like I just needed to remove the old KDE package. Now konqueror works fine. But k3b still reports...

k3b: Symbol `_ZTI18KUniqueApplication' has different size in shared object, consider re-linking
k3b: Symbol `_ZTI9KComboBox' has different size in shared object, consider re-linking
k3b: Symbol `_ZTIN6KParts14DockMainWindowE' has different size in shared object, consider re-linking
k3b: Symbol `_ZTI11KMainWindow' has different size in shared object, consider re-linking
k3b: Symbol `_ZTIN6KParts8PartBaseE' has different size in shared object, consider re-linking

...I wonder where this comes from.

And even those messages from k3b must just be warning, since I just successfully burned a DVD.

Why not just upgrade to Slack v10.2? You'll automatically get a KDE upgrade, plus numerous other upgrades as well.

Because it is easier to just upgrade KDE libs than the rest of my system.

I had to upgrade the following packages from Slackware-current to get KDE 3.5 working good on my Slackware 10.2.

x/*
kde/*
l/glibc
d/gcc
d/gcc-g++
l/libpng
a/acl (new package)

make sure you use 'upgradepkg' and not 'installpkg'. This prevents conflicting versions of multiple installs.

True, it's easier to upgrade just one aspect of your system, just as it's easier to paint one wall rather than the entire room. It's your system and whatever choice you make is entirely up to you, but I'd point out that v9.1 was released in Sept 2003, and many improvements in both the kernel and the distro itself have happened in the past 3 years. Perhaps a full upgrade would not be beneficial for your particular situation, but the only point I was trying to make was that spending a little extra time to bring everything up to date rather than just the DE wouldn't be a bad thing. Your call though, good luck with whichever route you choose to take.

I just do all of my upgrading incrementally, instead of all at once. So going to something like 10.2 would be a step backwards for me in terms of kernel, glibc, (and now) KDE, etc.
