QT errors

For two programs now that I have tried compiling via their included "configure" scripts, I get an error similar to:

Code:

checking for Qt... configure: error: Qt (>= Qt 3.0) (headers and libraries) not found. Please check your installation!

I have searched on this and it appears to be a common error, but it has been a very long time since I have extensively used Linux and can't make heads or tails of any fixes, although I've read that it is bound to KDE, which is what I'm using (under Fedora).

Ideas?

This specific error is when I try to compile KDevelop.

Well the error is pretty self-explanatory -> Qt is not found on your system. Qt is a windowing toolkit used by, among other things, KDE. If you're using an RPM based distro you need to install Qt and Qt-devel (headers are in the devel package).

When I do a locate qt, there is a version 3.1 installed at either /usr/lib/qt-3.1 or /etc/lib/qt-3.1 (I'm not on the machine ATM so I don't remember which). Is this incorrect? If so, would the necessary QT RPM be buried on the Fedora CDs or should I download (and possibly compile) it?

It's not that Qt is not installed, it's that the Qt headers aren't installed. Having Qt installed so applications can use it is one thing (like a DLL on windows) but having it so that you can compile programs that use it is another thing altogether. You need the qt-devel package installed because only that includes the header files that this program you're compiling needs.
