(fwd) Configure for a program that uses QT fails

["Axel H. Siebenwirth" <axel@hh59.org>]

Hi, I posted this to linux-newbie already. But now I still hope that you
linux administrators can help me. The problems is about linking qt
libraries? Well, any configure of a program that uses qt doesn´t find my qt
libraries, either qt2 or qt3.

Hi,

I´m completely desperate. Several times I have tried to build programs from
source that use the QT library. Now I again tried to configure kdevelop, but
it never succesfully finds the qt libraries. I have no idea whats wrong.
Everything should be ok. Every other source I want to configure for a build
and that uses qt fails as well.

Please help me! Give me hints on what I could do or check for..

Thank you very much in advance,
Axel Siebenwirth
