./configure error when compiling arts-1.1

[garethrussell]

I'm trying to install KDE 3.1, and ive installed Qt 3.1.1. When i run the ./configure script for Arts i get this error message:

checking for Qt... configure: error: Qt (>= Qt 3.1 (20021021)) (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!

I'm sure i installed Qt with thread support, as per the insturctions for compiling KDE 3.1. I'm running Mdk 9.0, can anyone help?

Have you set QTDIR with "export QTDIR=/path/to/qtdir"
check with "echo $QTDIR"

otherwise run "./configure --help" and look for an option like "with-qt-dir" and try using that.
