Hello !

Here is more compiling problems ;-)

1 Downloading program foo in source format.
2 unpacking the foo.tar.gz
3 open a terminal in folder foo , then running ./configure
resulting in error messages at the end , here's a dump:

checking for Qt... configure: error: Qt (>= Qt 2.2.2) (libraries) not found.
Please check your installation!
For more details about this problem, look at the end of config.log.

4 typing more config.log , dump:

configure:5271: checking for Qt
tried NO
tried /usr/lib/qt-3.0.4/lib
tried /usr/lib/qt-3.0.4
tried /usr/lib/qt2/lib
tried /usr/lib/qt2
tried /usr/lib/qt/lib
tried /usr/lib/qt
tried /usr/X11R6/lib
tried /usr/lib
tried /usr/local/qt/lib
tried /usr/X11R6/lib

5 As I understand things I do have the qt stuff installed, dump:

bash-2.05a$ cd /usr/lib/qt
bash-2.05a$ ls
bin doc include lib mkspecs plugins templates
bash-2.05a$ cd lib
bash-2.05a$ ls
libeditor.prl libeditor.so.1.0 libqt-mt.so libqt-mt.so.3.0.4 libqui.so.1
libeditor.so libeditor.so.1.0.0 libqt-mt.so.3 libqui.prl libqui.so.1.0
libeditor.so.1 libqt-mt.prl libqt-mt.so.3.0 libqui.so libqui.so.1.0.0
bash-2.05a$ cd /usr/lib/qt-3.0.4
bash-2.05a$ ls
bin doc include lib mkspecs plugins templates
bash-2.05a$ cd lib
bash-2.05a$ ls

libeditor.so.1 libqt-mt.prl libqt-mt.so.3.0 libqui.so libqui.so.1.0.0

6 What is missing ?

I could add that I have compiled other programs, where the
configure script has found the qt librarys.

Since QT is not backward compatible I suspect that it is only looking for QT version 2.2.2 or greater of version QT2. Slack 8.1 includes QT3, but not QT2.

Suggestion, download QT 2.3.2 I think was the last version of QT2. Follow the directions. When it has completed, make sure the installed directory is listed in /etc/ld.so.conf and run the command ldconfig. The directory would be /usr/lib/qt-2.3.2 if I recall correctly. Also, make sure the /usr/lib/qt does not point to the QT2 version. It needs to remain as QT3 or else KDE and other apps will fail.

Good luck.

Hmm . .
where do one find a qt2 package ?
checked at slackware.org , there was an entry in current/kde
but there was no file to download !

So it is possible to compile apps using qt2 and run them in
kde 3 ?

If I find the qt2 package , how to install it without change those present links to qt3 (how to not mess it up . .)

Try ftp://ftp.trolltech.com/qt/source/qt-x11-2.3.2.tar.gz they should have the current and past versions available.

As far as not messing with QT3, all I can say us that after the install of QT2 is completed. Then check the sym link /usr/lib/qt and if it is pointing to the new qt-2.3.2 directory then change it back to the qt-3.0.4 directory.

rm /usr/lib/qt
ln -s /usr/lib/qt-3.0.4 /usr/lib/qt

should do it. It would probably be best if you not running X at the time you installed QT2.
