This afternoon I did an upgrade from Gutsy to Hardy on my main development environment. I experienced *almost* no disruption to my system, with one exception (so far!). When I instantiated a ColdFusion 8 application which instantiates a webservice onApplicationStart, I received the following exception:
jikes: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory
Jikes! Well fortunately the fix is quite simple. Go to a terminal and install libstdc++5 like so:
$ sudo apt-get install libstdc++5
Restart your application and carry on! I am not sure what changed between the distros, but apparently the libraries that ColdFusion uses for invoking webservices depend on this package.
