It all depends on whether you want to develop for Qt 1 _and_ Qt 2
or only one of them. In the first case, things are quite complicated.
In the latter case, things are roughly as follows: The qt1/qt2 packages
only contain the shared libraries. Header files are in separate
packages qt1g-dev (or similar). That's certainly the case on Debian,
and to the best of my knowledge also for RedHat. The header files are
installed under /usr/include/whatever and should be found by the
configure script (if you use a autoconf/automake setup).
On the linker side: If you give the linker a command line option
'-lqt' (as is the case if you choose Qt in KDevelop's project
options), then the linker looks for a file libqt.so in standard
locations and perhaps in directories listed in the environment
variable LIBRARY_PATH. This file must be a symbolic link to the
actual library. So if you want to link with Qt 2, then libqt.so
(in /usr/lib or /usr/X11R6/lib IIRC) must be a symbolic link to
That should be all. There may be some pitfalls with the configure
relying on one version or the other though.
