Upon upgrade to Ubunt 9.10 (Karmic Koala) the libstdc++.so.5 library was removed, which breaks compatibility with older apps. When trying to run such an app, you will get an error:
error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
To fix, on a 64-bit system:
| $ cd tmp $ wget http://security.ubuntu.com/ubuntu/pool/universe/i/ia32-libs/ia32-libs_2.7ubuntu6.1_amd64.deb $ dpkg-deb -x ia32-libs_2.7ubuntu6.1_amd64.deb ia32-libs $ sudo cp ia32-libs/usr/lib32/libstdc++.so.5.0.7 /usr/lib32/ $ cd /usr/lib32 $ sudo ln -s libstdc++.so.5.0.7 libstdc++.so.5 |
