Qt headers not found!

[dempl_dempl]

Ok, I have problems with compiling Basic KDE App with KDevelop.
when I run ./configure I get the output :


---------------------------------------------------------------------------------------------------------------------------
checking for Qt...
configure: error: Qt (>= Qt 3.2 and < 4.0) (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!
*** Exited with status: 1 ***

Ok, I'm not stupid I've installed Qt , both versions 3 and 4 using "apt-get install".

I've searched the forum but I couldn't find anything directly concerning this problem.

Now , when I type the following:

$apt-cache search libqt | grep mt

I get theese results:
----------------------------------------------------------------------------------------------------------------

$apt-cache search libqt | grep qt4

I get theese:

Is there something missing or wrong here?
Should I simply try to install Anjuta?

BTW, I use Kubuntu feisty, and compiling terminal c++ apps works.
Kdevelop is 3.4.0.

Hey I found in other forums this wonderful solution (assuming you do have all the QT elements installed and you are still receiving the error)
export CC=/usr/bin/gcc-4.1 (use whatever gcc version you have)
export CXX=/usr/bin/g++-4.1 (again, use whatever g++ you have)
export CPP=/usr/bin/cpp-4.1 (and finally for those with no learning curve... use whatever cpp you have)

now you are ready to ./configure

I have already try to use your suggest with reinstall libqt3-headers libqt3-compat-headers, but until now I still get same error like this :

" configure: error: Qt (>= Qt 3.0.3) (headers and libraries) not found. Please check your installation!"

I want to use KsqlAnalyzer to connecting MS SQL Database

Anyone can help me ..?

Thx

I had that error when installing new k3b 1.0.2

"Qt (>= Qt 3.2 and < 4.0) (headers and libraries) not found"

but the libavahi-qt3-dev fixed the problem. I'm pretty green in this so I'm not sure if it help you.

libqt3-headers solves the "Qt (>= Qt 3.2 and < 4.0) (headers and libraries) not found." problem. However, the "KDE... configure: error" keeps coming.

And use this method to solve the KDE header problem.

Hi I have tried all of the suggestions on this thread. I am trying to install Knights (a KDE based 3D-chess GUI) I am getting the following error

checking for Qt... configure: error: Qt (>= Qt 3.0) (headers and libraries) not found. Please check your installation!
For more details about this problem, look at the end of config.log.

I suppose I could post the contents of config.log, but I found them fairly unilluminating. I have just about every qt4-dev file installed. Should I be trying the qt3-dev files instead? By the way. I have tried finding .deb packages for this program, found at least one, but had no success at getting it to install.
