Hm, it is strange that he says that he is not able to find libstdc+
+,... is it installed in one of the system lib directories (like /usr/
lib)?
I would understand if he couldn't find e.g. libQt(Core|Gui|etc),
though, because it seems that you run eclipse with a non-standard
configuration directory.
Unfortunately we don't handle this properly at the moment.
Workaround:
a) Use a local eclipse installation, where you have write access to
<installpath>/eclipse/configuration
and run eclipse either without a -configuration commandline option or
explicitely with
eclipse -configuration <installpath>/eclipse/configuration
or
b) Setting LD_LIBRARY_PATH to <installpath>/eclipse/plugins/
com.trolltech.qt.linux.x86_4.3.0/lib *should* also work, since there
are the libraries that libqtdesigner.so needs, though you might get
problems if you have other Qt 4 libraries installed.

You find the error log in eclipse under Window -> Show View -> Other -

Well, I am on SuSE Linux 9.3, and there I only have libstdc++.so.5,
but eclipse is looking for libstdc++.so.6.....
I think this is the problem.

it seems to be the same reason:
java.lang.UnsatisfiedLinkError: /ford/log00002/u/rneuber1/org.eclipse.osgi/bundles/138/1/.cp/lib/libqtdesigner.so: libstdc++.so.6: Kann die Shared-Object-Datei nicht Ãffnen: Datei oder Verzeichnis nicht gefunden
