After successful upgrade Ubuntu Linux from 9.04 (Jaunty Jackalope) to 9.10 (Karmic Koala) on my laptop, I’ve found that my TIBCO Designer is no longer works here:

./designer: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

I’ve found that libstdc++.so.5 isn’t available in Karmic repos anymore but still in Jaunty here: http://packages.ubuntu.com/jaunty/i386/libstdc++5/download. You can download and install it:

wget http://mirrors.kernel.org/ubuntu/pool/universe/g/gcc-3.3/libstdc++5_3.3.6-17ubuntu1_i386.deb
sudo dpkg -i libstdc++5_3.3.6-17ubuntu1_i386.deb

After that Designer runs great on Karmic.
