So I recompiled QT 3.3, and got the same thing. What can I do?

Make sure the QTDIR environment variable is pointing to the install?

How do I do that? I may have been using Linux for a year, but I haven't really gotten deep into it yet.

Ok, I did that, and then it found QT, but then this error came up:

checking for Qt... libraries /home/simon/Desktop/qt-x11-free-3.3.4//lib, headers /home/simon/Desktop/qt-x11-free-3.3.4//include using -mt
checking for moc... /home/simon/Desktop/qt-x11-free-3.3.4//bin/moc
checking for uic... /home/simon/Desktop/qt-x11-free-3.3.4//bin/uic
checking whether uic supports -L ... yes
checking whether uic supports -nounload ... yes
checking if Qt needs -ljpeg... no
checking for rpath... yes
checking for KDE... configure: error:
in the prefix, you've chosen, are no KDE headers installed. This will fail.
So, check this please and use another prefix!
[simon@localhost kbfx]$

So, where exactly are the KDE headers? I chose /usr/lib/kde3, but that didn't work.

It would be good to know the prefix you're trying to configure for. If you haven't specified a prefix as an option to configure then its most likely /usr/local

If it's /usr then all you should need to do is install the relevant kde*-devel packages. A quick way to get these would be to install kdevelop as the kde*-devel packages are dependencies of that.

If the prefix isn't /usr then you also need to specify the location of the kde libraries and headers - run ./configure --help and find the option for this. You could have probably done this with the qt stuff as well instead of setting the QTDIR environment variable.

I think I am supposed to se --prefix=/path/to/kde/headers for that, but I dont know where they are. On a normal Mandriva 2005 system, does anyone know where they are?

To solve your problems you need to install the libkdecore4-devel and libqt3-devel. After that run your ./configure script again.
