Thanks for your answer. After defining the LD_LIBRARY_PATH
Code:
# export LD_LIBRARY_PATH=/usr/lib/firefox-2.0.0.6/
ldd found the libraries, but invoking thunderbird gave me now
Code:
error while loading shared libraries: libmozjs.so:
cannot open shared object file: No such file or directory
So I created symbolic links in the thunderbird directory to the mentioned libraries and also to run-mozilla.sh, because thunderbird was also complaining about missing mozilla-runtime. Now I finally don't get any error messages anymore but nevertheless still no thunderbird. Any ideas?
