./configure can't find Qt

I went searching for this problem first, and I found someone else was having the same problem, but it was due to them having a 64-bit processor, which I do not.
The problem is, when I run ./configure (I'm attempting to install KWanda for reference) it tells me it cannot find "Qt ( QT >= 2.2.2) (libraries)", but I am using Qt 3.(something), and I have compatiblity packages installed too.
I tried using the --with-qt-libs option, giving it all the possible locations the library files it is looking for could be (e.g. /usr/libs/ /usr/libs/Qt3/ etc. I looked in KPackage to see where files went from the QT install) but still no luck...
Does anyone have any ideas?

In my installation of Knoppix, they're in /usr/lib/qt3 (note the lowercase qt3). I'm not certain that's causing the error.

I'll give it a go when I get home, but I'm pretty sure that's what I tried. Is it possible that the KWanda configure is looking for something that's not in later versions of Qt? I think it's unlikely, as I have the Qt-compat package installed, but is it possible?

Have you installed the -devel packages for Qt? To compile something against something else you need the includes files that are installed by -devel packages

I have a similar problem, although I'm trying to compile kde!

I've compiled the qt libs from source, so I know that I have them and the devel files, I also know that I compiled it with thread support.

There must be some reference somewhere that I'm missing, although I've tried as many as I can think of.
(my path to the qt dir is /usr/local/qt)
CPLUS_INCLUDE_PATH=/usr/local/qt/include
LD_LIBRARY_PATH=/usr/local/qt/lib
QTDIR=/usr/local/qt
PKG_CONFIG_PATH=/usr/local/qt/lib:<stuff> (this is where it keeps qt.pc and qt-mt.pc)
PATH=/usr/local/qt/bin:<stuff>

but configure still fails with:

checking for Qt... configure: error: Qt (>= Qt 3.3 and < 4.0) (library qt-mt) not found. Please check your installation!
Make sure that you have compiled Qt with thread support!

Funny thing though, I even got this error when I let kde compile and install qt as well!

Can anyone think of something I may have missed? What else can I do to debug this problem?

Try running

Code:

./configure --help

and look through the available options. There should be options to point it to where the qt libraries and include files are.
