I am having problems with compiling any program for KDE3. I am using the Red
Hat rpms on a Red Hat 7.1 system.
Any help is appreciated.

This is the error I get during a configure...
checking for Qt... configure: error: Qt (>= Qt 3.0.2) (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!

"ldconfig --verbose" produces the following
/usr/lib/qt-3.0.3/lib:
libqxt.so.0 -> libqxt.so.0.3.0
libqui.so.1 -> libqui.so.1.0.0
libqt.so.3 -> libqt.so.3.0.3
libqt-mt.so.3 -> libqt-mt.so.3.0.3
libeditor.so.1 -> libeditor.so.1.0.0
/usr/lib/qt2/lib:
libqxt.so.0 -> libqxt.so.0.3.0
libqutil.so.1 -> libqutil.so.1.0.0
libqt.so.2 -> libqt.so.2.3.1
libqt-mt.so.2 -> libqt-mt.so.2.3.1

Stab in the dark. What does your QTDIR and LD_LIBRARY_PATH
look like?

QTDIR=/usr/lib/qt3 (which is a symbolic link to qt-3.0.3)
LD_LIBRARY_PATH is blank

Even tho ldconfig has /usr/lib/qt-3.0.3/lib, I would set
LD_LIBRARY_PATH so that it has /usr/lib/qt-3.0.3/lib.

before compiling :

export QTDIR=/usr/lib/qt-3.0.3
export KDEDIR=/your/kde3/root/dir

or

./configure --prefix=/your/kde3/root --with-qt-dir=/usr/lib/qt-3.0.3

Well, I tried that and it didn't work. So, I downloaded the source and
compiled it myself. Everything is working now. Strange that the rpm didn't
just wouldn't do it for me. I hadn't found any evidence of anybody else
having a problem.

Sure that you didn't forget to install the devel package?

I am getting the exact same message. I am using SuSE 8.0.

At first I was using the stock g++, unfortunately, I could not get
exceptions to work, no matter how I configured
the project options. So I decided to try g++3.0. And it started
complaining about lib qt-mt.

All the libraries are there. /usr/lib/qt3 points 3.0.3 and libqt-mt.so
points to libqt-mt.so.3 ....
QT_VERSION is 3.0.3 in the qglobal.h file. and there is no other QT_VERSION
anywhere else.

Yet, it complains that (lib)qt-mt is not found.....

I am at a loss....

beware that if you use a different compiler than stock, you must recompile
ALL your c++ libraries/applications from scratch.
C++ ABIs aren't compatible from one compiler version to
another.

Yep, that's what I found out today. Compiled and installed qt from sources.
Everything compiled but link didn't work with SuSE KDE 3.

So I am back to stock everything. I guess I have to figure out why
exceptions don't work...

Are you trying to use exceptions in self-written KDE or Qt programs? KDE
programs are by default compiled with -no-g++-exceptions, because neither
Qt not KDE uses them and because they're damn expensive wrt memory usage.

It was self-written on Solaris using pccts/antlr. It is about
300,000 lines of code ( with about a 30 meg executable. ) . Original
code was not gui driven, but
command line. It is a huge tree traversal based code. So exceptions
are very heavily used ( so is pthreads). Originally I had also used
Rogue Wave tools.h++
however that I've already converted to stl and boost.
