"Leaving the directory" in not an error, just a message what make is currently doing. If you have any errors, they are probably earlier in the log.

Have you read README and INSTALL files that come with Qt sources and run configure script before "make"?
Also please, don't start multiple threads on the same problem.
thank you Jacek
when I downloaded the evaluation version one error I got like"Error reading header after proceesing 0 entries..
qt-x11-eval-src-4.2.0.tar, is this Qt version compatable with red hat 9
Here are the steps to be followed
1. After you download the Qt tar.gz file
2. Unzip it : tar xfvz qt-x11-eval-src-4.2.0.tar.gz
3. Go to the unzipped folder
4. run configure : ./Configure
5. start compilation : make
6. if make is successful, now you can install it. for that
7.login as root : su
8. install Qt4.2 : make install
Now you have it installed, probably in /usr/local/Trolltech/Qt-4.2.0
set the path to the new qmake by issuing
PATH=/usr/local/Trolltech/Qt-4.2.0/bin:$PATH
then try compiling
Maybe there was some error during the transmission and that file is corrupted? If there is MD5 sum available on the website from which you downloaded that file, you can check if the file is correct.Quote:

But still my designer for QT4.2 is not opening .im Still Having designer for Qt3.11.
What shall i do to get Designer in Start up.
Did you give a make install ?
if so, then see if it is installed in /usr/local/Trolltech/Qt...
and then set that path in the path environment variable ...
One more thing
How do you open the designer ? is it thourgh the same shell in which the path has been set ? It is a common mistake to set the path in one of the terminals and then trying to open it from the start menu...
So once the path has been set. simply type designer & see which designer pops up ? if you still don't get the Qt4 designer, post the result of " which designer "
hi,
I tried which designer .this is the result.can you find the problem
[nimmyj@localhost sample]$ which designer
~/qt-x11-opensource-src-4.2.2/bin/designer
[nimmyj@localhost sample]$ designer &
[1] 2410

hi Sunil,
we also tried doing one example with out dessigner. it created pro file and make file was made but some error came.

hi sunil,
we had set envirn variable for library wrongly .we changed it and dessigner is getting open when dessigner & is given.now the only problem is running example program from console.
