libstdc++5 in ubuntu Lucid

Warning - Old Content

This post is quite old, and it might not apply anymore, or maybe there's a better way to do the same thing nowadays. Take with a big grain of salt.

Apparently ubuntu removed the rather-old libstdc++5 library in Karmic Koala, and it’s still missing in Lucid Lynx. This leads to some 32-bit programs throwing errors like this:

error while loading shared libraries: cannot open shared object file: No such file or directory

There is a ppa (personal package archive) you can add to re-enable this. Note that it has to be “karmic” even if you’re running a later release. These instructions are taken from the official bug report, and will work for amd64 (not sure about 32-bit architecture).

Add these 2 lines to your /etc/apt/sources.list (or use the package management app):

deb karmic main
deb-src karmic main

Then import the key and install the required package:

sudo wget -q '' -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install lib32stdc++5

Full bug, with several possible workarounds
