Re: KDE apps look strange with 2.2.1 on a PowerPC machine

I think I have made some progress tracking this down though - by some horribly time-consuming playing with LD_LIBRARY_PATH (server side) I've confirmed that this path :
/afs/cern.ch/atlas/offline/external/LCGCMT/LCGCMT_54f/InstallArea/ i686-slc4-gcc34-opt/lib
gets add to LD_LIBRARY_PATH during our setup script, and it's this (and only this), that causes the problem.

Oh dear. That directory replaces just about every client-side X11 library above libX11 itself.


But I think we have a likely culprit: it replaces libqt-mt.so.*, which is the Qt toolkit core on which KDE applications depend --- and which, among many other things, handles the interface to client-side font rendering. Very likely it is missing some bugfix which removed an endian bug.

You can check what libraries it uses on the Linux machine:

LD_LIBRARY_PATH=/afs/cern.ch/atlas/offline/external/LCGCMT/ LCGCMT_54f/InstallArea/i686-slc4-gcc34-opt/lib ldd /usr/bin/kate | grep LCGCMT

(that will almost certainly wrap, but it is a single line)
which will give you a good idea of what libraries are interfering.

Unfortunately, barring a vendor fix, you'll have to use a wrapper (or shell function or maybe alias) to force LD_LIBRARY_PATH back to the default to run kate and other KDE applications.
