Getting 32-bit libstdc++.so.5 in {Karmic Koala,Lucid Lynx} on a 64-bit system

The Intel compilers require a 32-bit version of libstdc++.so.5 to function. Getting a copy of that build of that library requires a couple of steps in the latest 64-bit Ubuntu {9.10,10.04}. These have been alluded to in other places.  Just in case someone needs the details, here they are:

  1. Download the i386 libstdc++ package for Jaunty: http://packages.ubuntu.com/jaunty/i386/libstdc++5/download
  2. Unpack the .deb archive using ar vx ~/Desktop/libstdc++5_3.3.6-17ubuntu1_i386.deb
  3. Unpack the resulting data.tar.gz using tar xzvf data.tar.gz
  4. Confirm that you got the 32-bit version using file usr/lib/libstdc++.so.5.0.7
  5. Install the library into /usr/lib32 using sudo install usr/lib/libstdc++.so.5.0.7 /usr/lib32
  6. Change to /usr/lib32 using cd /usr/lib32
  7. Create a symlink to finish the task via sudo ln -s libstdc++.so.5.0.7 libstdc++.so.5
Many thanks to everyone who provided the source material:

Updated 24 April 2010: Appears that this procedure also works on the Lucid Lynx release candidate.
