KDE 3.1 RC3: Last Dance?

The KDE Project today released KDE 3.1 RC3 with fixes for several severe bugs in RC2. This RC is likely the last before 3.1 although there remain a few items on the TODO list for KDE 3.1. If you find a showstopper problem in this release candidate not yet listed on bugs.kde.org, please file a report as soon as possible. The download links are up as usual on the KDE 3.1 Info page.

Yes, i had this problem too. Make sure that fontconfig and fontconfig-devel are installed.

Qt didnt link them in automatically for me, so i had to do a:

find . -name Makefile | xargs perl -pi -e 's/-lXft/-lXft -lfontconfig'

and then remove libqt-mt.s* and rerun make.

YES! I am getting this right now using Mandrake Cooker! I dont know how to fix it, have you since your post?

by chuzwuzza (not verified)

I had to add -lfontconfig to the libs section of the makefile of whatever directory that was in. I had those exact same errors.

KDE 3.1 is shaping up to be the best desktop experience I've ever had on the x86 platform. Great job guys. I got the blinking icon issue that 'aligning to grid' didn't fix :(

by kidcat (not verified)

the alling to grid only fixed in rc2
if u want it fixed u can just disable devices on the desktop

Does anyone know what flags I have to set to get the newer video features working. Things like video thumbnails, an embedded video player that actually embeds the video, and using xinelib to play the video. Am I missing some flags when I compile kdemultimedia, or did this work get delayed to 3.2?

Konqueror times out...
Traceroute returns !H (host unreachable ICMP message), last hop:
11 tbr2-p013701.sl9mo.ip.att.net ( 46.737 ms !H 67.281 ms !H 46.452 ms !H

I'm running Mdk 9.1 Cooker, now on KDE3.1RC3, from the cooker RPMs. Kept upgraded via URPMI from an original Mdk 8.1 install.

I was going to attempt to check on, and possibly report, the crashes I've been getting in Konqueror... Often times, it will partially load a page... and freeze solid, no crash report or anything. KWin won't close it... I have to hotkey XKill, and click the window.

Also, I haven't been able to load KNewsTicker graphical config in some time. Clicking the config option does nothing.

These bugs have continued to persist thru the several RCs, at least. The Konqueror one is the most frustrating...

bugs.kde.org hasnt really matured after the transision to bugzilla..
i get wierd square-symbols when i have to pick the severity of the bug... i dont know it this is Konqi that is buggy or it is The Bug that is buggy.

Could some one with kde3.0.x try and make a bugreport and just bail out just before submitting it? If you dont c a *totally* goofed up selection of "bug type" let me know so i can file yet another bugreport :)

The "can't access configuration for this-and-that" stuff is about 99.99% certain to be MDK packaging bugs -- until the MDK menu stuff is completely updated for the KDE Control Center changes in 3.1, expect those. I'd strongly suggest you switch to using vanilla KDE menus for a while (use menudrake to do that). That's one reason why some people would like testers to just use sources..

As to Konqueror freezes.. Never saw one myself, so no idea on what's going on.. I suspect none of the Konqui devels have either, or otherwise there would be a bug with a really scary severity rating attached. Nor do I recall anyone reporting a bug like that - and I am subscribed to kde-bugs-dist.. But here is one thing that might be useful: if the problems happens *really often*, go to konsole, run konqueror in gdb (just do gdb konqueror, and then type run at the prompt). Then go do some browsing in the window. When it freezes, go back to the konsole, and press ctrl-c. Then type bt. It will tell you where in the code konqui was when you interrupted it.. Then press cont, wait a few seconds, and repeat the deal with ctrl-c. Then save the output, and report a bug. Of course, if you find a way to reproduce the bug consistently, it would help the most in diagnosing and fixing it. (You can also attach gdb to running processes - but I don't know a good way of figuring out which is the *right one*)..

Hi.. just my two cent humble opinion.

The icon for ControlCenter looked much better in rc2.. however i use the Large size panel.. so i dont know if its because it didnt scale well.

The reason i like the old one better is that it was blue... this one just doesnt fit in with rest..

And while im at it.. the HelpCenter icon is now *screaming* out.. i dont know if this is the idea with it.. but it too spoils the nice crystal-blue drool-o-rama that is everywhere else.. besides Kmail.. the K should be blue too.. not that old kde-2ish orange.

Just my two cent...


by kidcat (not verified)

Surgestion for a new HelpCenter icon:
A crystalic blue book with [a] yellow (like the "eye" of the [K] button) question mark[s] on it.

It would be really awesome if all the standard icons oh the panel really showed the "essence" of the Crystal-SVG icon set.. which is why i allso vote for at "bluishing" of the [K] button.. as it is now it has this really neat yellow crystal core.. but the gear around it and the K would (imho) benefit from a "crystalization".

Oh.. and while im giving it a whack at being an Art Krittique (everyone thinks themself qualified, huh?)... something needs to be done t othe shell ontop the screen of Konsoles icon.. it just doesnt look as "freindly" as it should.. and its hard to see that it is endeede a shell.. at first glance it looks like some kind of middle-east head-wear :)

HI all ..

whats the matter with the kdebindings at the moment? .. till rc1 i have to patch the makefiles like hell to get it running. In current rc3 dcopc looks really messed up. Somebody else with problems in this 'area' ?


by desau (not verified)

Not to add to ranting, but I've _never_ been able to make kdebindings compile completely. I have absolutely no problem with any other package of KDE.

The biggest pain from kdebindings that I get seems to be from the java and smoke bindings... even though I've got java installed and working fine.

by Need Help Compiling (not verified)

what's with this (starting w/arts? i certainly did compile Qt with thread support and i even tried passing --with-qt-dir=/usr/local/qt to ./configure

checking for Qt... configure: error: Qt (>= Qt 3.1 (20021021)) (library qt-mt) not found. Please check your installation!
For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!

What tells QTDIR?

by Need Help Compiling (not verified)

i have it in .bash_profile

# for compiling qt

by Kevin (not verified)

I am getting the same error, I've added this to my bash_profile and tried to ./configure and gmake QT 3.1 again (threaded) and i'm still getting this error, any ideas? I've spent a few days trying to firgure this out and there isn't really much help on this error. anymore ideas?

by Kevin (not verified)

I answered my own question, though i'd share...

while also adding the above information to my .bash_profile I used this config option...

./configure --with-qt-dir=/usr/local/qt/ --with-qt-includes=/usr/local/qt/include/ --with-qt-librries=/usr/local/lib/

by Dieter Kraft (not verified)

Did you get it running?
I have the same problem.

If u have already compiled the QT, run make distclean or make confclean, and ./configure -thread

Hi ,
I am also getting this error while configuring for Juke music application. I have compiled Qt earlier(without -thread) option. But now i get the following message:

For more details about this problem, look at the end of config.log.

any help on this will be preceous for me.

by William Y. (not verified)

I have compiled QT with thread support, and I still have the same problem. I tried passing --with-qt- flags as well, nothing works. So NO, recompiling it again and again won't solve the problem. Oh, and I use RedHat 7.2. It originally comes with KDE 2.x and QT 2.x. I, however, chose not to install any desktop environments during the installation process. I then downloaded the latest version of XFree86, installed that. Then I built QT 3.1.1. Any ideas?

Thanks in advance,

I had a similar problem in my Qt installation (3.3.3)

I found a broken link in the Qt lib directory ('/usr/lib/qt3/lib/' in my distro). My linker found libqt-mt.so, a link which was pointing to an outdated shared library that wasn't there. I did have a shared lib 'libqt-mt.so.3.3.3' in the same dir, but the broken link was sending it to a nonexistent 'libqt-mt.so.3.2.3'. This probably explains the "can't find library qt-mt" error message. So I deleted the stale link and made a new one that pointed to the correct file, and all worked fine! Apparently when they made a new version of Qt they forgot to update the links!

hope this helps!


by Munky (not verified)

I found close to the same

I had /usr/lib/libqt-mt.so.3, but no corresponding link of /usr/lib/libqt-mt.so

so while I had a versioned lib, I had no base, so nothing could find it unless it was looking strictly for so.3

by Omer Moussaffi (not verified)

I have found the same problem on Mandriva. I soled it by using prefixes for the QT folder. I had to manually add the KDE folder into the configure file (around line 22733). Then it worked.

by skontog (not verified)

For slackware just link libqt-mt.so.3.3 to libqt-mt.so

by Tim V (not verified)

Are you sure that you compiled Qt 3.1 (yes 3.1) and had the right flags (like -thread or something) in it?


by cme (not verified)

It's not due to missing qt-mt, the test failes for some other reasons, unfortunately I can't remember exactly.Check config.log, I think it was something like missing /lib/cpp

by Need Help Compiling (not verified)

A clue?

[root@prospero bin]# qtconfig
qtconfig: relocation error: /usr/lib/libXft.so.2: undefined symbol: FcInit

i do have xft, fontconfig, etc. installed, did use the -xft switch, and it does at least appear to have compiled in. could this be related?

by dude (not verified)

I got mine to work with this: ./configure --with-qt-dir=/usr/local/qt --with-qt-includes=/usr/local/qt/include/ --with-qt-libraries=/usr/local/qt/lib/

by Dofik (not verified)

Hi I just fixed that problem:
This is two way - longer and shorter :)
First some explanations:
Problem: qt compiled with different gcc than your project try to. thats all

shorter change your symlink back to gcc-2.95 (or 6),
and g++ too so
dcgui-0.2# gcc -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20011002 (Debian prerelease)

dcgui-0.2# g++ -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20011002 (Debian prerelease)
and all be fine.

Longer method
use gcc.3 and above to compile qt ( with thread support!!!) and any other libraries needed in project .

by Khaled (not verified)

That was it! Thanks a lot!


by joco (not verified)

I know, that it is a stupid question, but how can I compile qt with thread support? Can anybody say me, what should I exactly do?


by Anonymous (not verified)

configure --thread --dont-forget-other-options

by lonestar (not verified)


I´ve got the same problem here. I even tried --with-qt-lib ... etc - always te same error :(

I used the qt-configure options used in the howto of kde-compile.

someone any ideas?


by Joe (not verified)

I have the same problem. I've compiled with gcc 3 and I still cannot get that damn qt-mt library error to go away. Im a gentoo'er and there isnt anyone over there that seems to know the solution.

Any suggestions would be great.

by psyche101 (not verified)

Howdy all

Seems alot of us are getting his - anyone had this on Freebsd ? I am running 4.7-RELEASE. Semi-newbie.

by alqama (not verified)

i am using redhat 8 and trying to install kopete on my system. i am getting the following error message. i installed qt with the installation of red hat.
any one knowing the solution....

"checking for Qt... configure: error: Qt (>= Qt 3.1 (20021021)) (library qt-mt) not found. Please check your installation!
For more details about this problem, look at the end of config.log.

by csae (not verified)

i've got exactly the same problem, except i'm using redhat 9 and installed qt-3.3.1, as it's required to run kde 3.2 (requires qt >= 3.2); by trying to install kdebase-3.2.0 i get the same error message as above: library qt-mt not found, check your installation and so on...
i've set all the environemtn variables and compiled qt with thread suport, but it won't work; anyone got an idea?

thanks for all help

kind regards,


by xeratul (not verified)

Did someone found ?

I have same problem. I did too:
export QTDIR=/usr/share/qt3

and apt-get install make build-essential gcc gcc-3.4 build-essential g++
and so on

by Mr.NEUTRON (not verified)

I'm using Mandrake 10 CE and had the same problem, (and little bit more grey hair :) !!!! So this meassage is mainly for mandrake users.
If you have ALL qt components installed:
1. Go to : http://urpmi.org/easyurpmi/index.php
2. Fill ALL boxes!!!! and "type in a console as root" ( for newbie write "su" and type password)


Try to install ALL gcc components e.g. fortran77, java
If have any problems with installation in rpmdrake, try use in console as root command: urpmi name.of.package.mdk.rpm

might be work

Good Luck :)

by Filipe (not verified)


i had the same problem as you, and found it strange as all packages were installed...

the problem was in fact the one described above - qt library was compiled with a different gcc than the one used to compile the program.

to solve:

rm /usr/bin/gcc
rm /usr/bin/g++

apt-get install gcc-3.3 g++-3.3

ln -s /usr/bin/gcc-3.3 /usr/bin/gcc
ln -s /usr/bin/g++-3.3 /usr/bin/g++

... and it should configure with no errors now

for the record this was done in debian unstable.



by Tjerk (not verified)

Sorry dude but that is not the solution for me.

I want to install an application that uses QT, i have QT installed, did it with
apt-get (debian). apt-get compiles it itself. then run the .configure script of the application i want to compile and it says:

checking for Qt... configure: error: Qt (>= Qt 3.2) (library qt-mt) not found. Please check your installation!

Well i did what you said. but:
tw:/home/tjerk/downloaded/activeheart-1.2.1# rm /usr/bin/gcc
tw:/home/tjerk/downloaded/activeheart-1.2.1# rm /usr/bin/g++
tw:/home/tjerk/downloaded/activeheart-1.2.1# apt-get install gcc-3.3 g++-3.3
Reading Package Lists... Done
Building Dependency Tree... Done
gcc-3.3 is already the newest version.
g++-3.3 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
tw:/home/tjerk/downloaded/activeheart-1.2.1# ./configure
configure: error: no acceptable C compiler found in $PATH

Well it makes the problem worse for me!!!

by Blackwing (not verified)

Yep! for me it was because of the different version of gcc compiler.. after replacing it with version 3.3, symlink it and voila!

thanks again for the workaround provided.. it cures my headache :))

You are missing the compiler (gcc), that is not the same problem.
