How to install QT on fedora?


Whenever I try to ./configure software, I get the message:
checking for Qt... configure: error: Qt (>= Qt 3.0) (headers and libraries) notfound. Please check your installation!

So I downloaded qt-3.3.3-0.2.src.rpm but when I click it it just opens like a zip would on windows (yes, Iīm a newbie-ex-windoz user). I currently have qt version 1.something installed. I just spent over two hours on google trying to figure this out, and came to the conclusion that there could be problems with version 3.* replaceing 1.*. So my questions are:
1) How do I install it?!?
2) Is it likely that there will be problem afterward?
3) Is there an alternative that will not be as likely to be problematic?

Thanks.

By the way, in APT I do not see an update for my qt 1.* and that also akes me suspect the stability of 3.*.

First, see that you have the qt libraries inlstalled (most likely you do have it installed):
ls /usr/lib/

It should contain a qt or a qt3 directory, or something similar. You have version 3 or above, version 1 is really, really old...

Or, test with using rpm:
rpm -q qt3

If it is missing (unlikely), install the qt package.
Then, install the qt3-devel package (apt or whatever you use).

Compile your app.

Sasho,
You are right I do have /usr/lib/qt-3.3 but when I rpm -q qt3 I get:
warning: cannot get shared lock on /var/lib/rpm/Packages
package qt3 is not installed

I just installed qt-devel with Synaptic and tried to ./configure again, same problem.

Masand,
I couldnīt find the qt package in Add/Remove programs (there is no programming section), but that is unnecessary because, well, it is installed! But not working...

Where to go from here? Why should ./configure think that qt >=3.2 is not installed when I do have 3.3? As I have found no advise on google, am I to assume that I am the only person with this problem?

type this in a console/xterm:
Code:
echo $QTDIR
and see if you get any output (it should print /usr/lib/qt-3.3)
if not then:
Code:
export QTDIR=/usr/lib/qt-3.3

Also, make sure /usr/lib/qt-3.3/lib is entered into /etc/ld.so.conf and run ldconfig

Code:
export QTDIR=/usr/lib/qt-3.3
export PATH=PATH:$QTDIR/bin
Good point __J, I forgot about those.

dotancohen, now that you have the devel package installed, maybe you can post the error you are getting during ./configure?

Quite a few qt-based programs are looking for the QTDIR variable. Also, modifying ld.so.conf will not put qmake in your path (if it isn't there already).

Thanks for everybodys help. I found out that I do have a current version of QT installed. For the archives, the whole story is available here:

QTDIR is not a temporary solution, as it is part of the install process for qt atleast according to trolltech:
