relocation error: /usr/lib/libkdecore.so.4: undefined symbol

Hello,

I've installed KDE 3.3.0 with Konstruct (meta/everything).

Since then, few programs don't want to start and say, eg.:

Quoted

[seb@localhost seb]$ kscd
kscd: relocation error: /usr/lib/libkdecore.so.4: undefined symbol: qt_x_user_time

Same if I want to compile my programs from KDevelop.

If I look at the filesystem, /usr/lib/libkdecore.so.4 is a symlink to /usr/lib/libkdecore.so.4.2.0 !

What can I do to have it working ?

Thank you.

The "undefined symbol: qt_x_user_time" error was happening when I tried to run a KDE 3.2 compiled program.

When I try to recompile a program from sources, I get this message during configure:

Quoted

checking for KDE... libraries /usr/lib, headers /usr/include
checking if UIC has KDE plugins available... no
configure: error: you need to install kdelibs first.

What is the problem?

I already installed KDE with Konstruct.

And why does KDE 3.3.0 break Binary Compatibility?

kde is not backward compatible, afaik. A package which was built for kde 3.2 is not guaranteed to work on 3.3. As far as your error, install kde-libs and the development packages first.

KDE should definitely be source and binary compatible to third party packages throughout the whole KDE 3 series!

I'm not sure if this applies to KDE itself internally though, so you may still be right in the case of kscd.

I find it strange that this error also appears when Sebien compiles programs using kdevelop though...

@Sebien:
AFAIK undefined symbols can come about if there's a version mixup where the wrong version of a file is picked up.

- Did you compile all of KDE using konstruct?
- Do you have any other/old versions of Qt or KDE around?

As far as I see, konstruct is very good to install KDE whitout knowledges.
But it's also very bad for tuning it: if a thing turn bad, you cannot do anything.

It's how I see it.

I have Mandrake Linux 9.2which comes with a KDE 3.1 version.
I've then installed Mandrake 10 packages for KDE 3.2.0. Some errors occured (such as an empty KControl, bad KMenu things caused by strange Mandrake modifications).
So I decided to install KDE 3.3.0 with konstruct.

I used meta/everything from konstruct KDE 3.3.
NO uninstallation first, and used the same "/usr" prefix.

If I remember, I tryed to reinstall some things after, like i18n-fr, and it finish by say :

Quoted

I'm afraid something like this could happened during installation.

Is there a way to use "--force" with konstruct.
I want it to override my previous i18n packages. Hey: it's what means by upgrading!
And same for whole KDE, but I got NO error when finishing meta/everything.

Forgotten to precise:

I get this problem when trying to run eventwatcher (3rd paty app).
But also when wanting to run KSirc, which is compiled by konstruct, I think.

I'm walking on thin ice here since I don't know either Mandrake or Konstruct (I've compiled my KDE manually), but you could try to remove the remainder of the original KDE installation using Mandrake's package tool. I'm not sure if there are any essential Mandrake programs that depend on these packages that might be wiped off your disk along with them... be careful.

Or you use Konstruct to install a fresh KDE to a *different* directory and use that.

This is finally fixed.

In fact, Mandrake installs QT in /usr/lib/qt3/...

And some times ago I added subdirectories in the path (or Mandrake done it itself).

Quoted

QTDIR=/usr/lib/qt3
PATH=$QTDIR/bin:$PATH
MANPATH=$QTDIR/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

export QTDIR PATH MANPATH LD_LIBRARY_PATH

Then the first files that was found was the old ones.
I deleted the dir (since Konstruct installed the new files in /usr) and it works.
