Since the QT 3 rpm got installed successfully, ideally, the program should have worked and that error shoudl have gone.But now that, it is still giving the error, download and install QT from the latest official sources (newer than that rpm):

ftp://ftp.trolltech.com/qt/source/qt-x1 ... 2.2.tar.gz

After u install qt from the sources, try that error giving compile again

mr Faraz.Fazil sir

sir jii this took really long time. Actually during installation of that qt from source, it took so much time after 'make' command. i waited for it to end for like one hour and still it didnt finish. I left it on and went to sleep

. When i woke up tow i came to know that power went off while i was sleeping and my computer was turned off abruptly bcuz of that. on booting again it started giving me errors during boot process, so i installed the whole thing again. the whole Linux. ok now again i started installing qt from source and it took about 2 hours and 15 mins in whole process

, and the tragic part is its again giving the same error

. but this time there is one new line in error that it is giving. i think i should show u the output, that will give u better idea of what i m saying:

=================================

checking for libpng... no
checking for libjpeg6b... no
checking for libjpeg... no
configure: WARNING: libjpeg not found. disable JPEG support.
checking for Qt... configure: error: Qt (>= Qt 3.0) (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!

=================================

Make sure that you have compiled Qt with thread support!

this is a new line. I didnt see this line in error messages before. and as far as i remember, it didnt give me any option to compile qt with thread support during whole process.

Thanks for ur precious time

Good Day

YOu know what?

Many linux users have had problems and errors Compiling QT from the sources and they have also encountered QT errors when compiling certain programs from sources (Just like in your case).So you are not alone hehe.

Many users have reported similar errors in the past.

Now, do this:

Issue these commands when compling qt from the sources:

1.make distclean

2.

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

The above config will also include thread support.

then run the make commands as usual.

It should work.

If the above does not work, then it may be a problem due to some config problem with gcc.In that case you may need to use these commands:

gcc -v
g++ -v

first and then recompile QT from the sources again (using the commands given before in the earlier part of this post.)
