Strange. I send a copy of this mail to Torsten Rahn from the KDE team,
perhaps he can give us some comments.

Hmmm, shouldn't be too hard to check if the files are in the assumed
places? Unfortunately, I don't know enough of the KDE stuff yet to be
really hepful in this department.

Not being an expert in autoconf things, this seems to be a problem with
your autoconf configuration files in the admin directory which seem to be
taken from a KDE1 installation.

Hmmm, at the moment I didn't install kmatplot at all, I just wanted to
test it in the directory where it was compiled. If I understood Torsten
correctly some time ago the KDEDIR variable is obsolete and is not being
used any more? However, compiling and starting from the directory without
being installed should always work, I assume. But also following your
hints doesn not work, I get the same error...

Uff ! I could vow that they are taken KDE-2.1.1, everything works well on my 
RedHat.

I'm afraid I didn't get it to work without installing before, you can't point 
KDEDIR to your build directory- it won't work, but you can always install it 
in your home directory. If you install a shared library in a non-library 
directory, you must also add it to LD_LIBRARY_PATH. Check if it works:

./configure --prefix=/home/kamil/kmatplot
make install
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/kamil/kmatplot/lib
env KDEDIR=/home/kamil/kmatplot kmatplot 

Did you do so ? I didn't see the post from Tortsen and I know nothing about 
obsoleting KDEDIR. It still must be set when program is installed in a 
non-standard directory.

Two possibilities: output an errormessage telling the user what's missing
where or installing a personal versinon of the files in the user's home
directory.

Hmmm, I'm not sure, but if you look at admin/acinclude.m4.in (where the
KDE_FIND_PATH ist defined) it has copyright messages up to 1999... But
again, I'm no expert, just a guess.

How do other applications perform the task of getting the right paths? Did
you look at the output of a KDevelop generated project? Btw, are you using
KDevelop? There is a project file, but e.g. the admin/ stuff we are
talking about here doesn't seem to be autogenerated to me...

Hmmm, strange. ldd says that kmatplot/kmatplot is not a shared library! So
I assume it is linked statically. At the moment I'm recompiling with
--with-kde-dir=3D/opt/kde2 and --with-qt-dir=3D/usr/lib/qt2. This takes qui=
te
a long time on my 300 MHz MII, so I assume I'll probably be able to give
you more success or error reports tomorrow morning.

I'll try it again if my current comiler run has finised and keep you
informed.

Sorry, a misunderstanding - there was no post here. I talked to Torsten
some time ago about another problem and during the discussion he mentioned
that KDEDIR should be obsoleted at that time; I'm not sure if this is
really the case in the mean time or not (havn't compiled KDE myself for
some time...).

You needn't to recompile if you keep all object files. Just reconfigure and 
reinstall. Kmatplot compiles itself very long, mostly those dialogs, Dialog 
editor generates four files per single panel, uff ! 
kmatplot in the build directory isn't a real program it is only a wrapper 
script which calls ./libs/kmatplot. It allows you to run kmatplot without 
adding path to a shared library ( part/.libs/libkmatplot.so ), but the 
problem with resource files still remains, so it won't work. I know no way to 
run kmatplot directly from the build directory. 
I checked source once again and it seems that program checks if resources are 
present but it just displays "libkmatplot not found" and crashes if there is 
a problem, I try to add a more descriptive message in the next version.
