Installing 32-bit libbz2.so.1 in 64-bit Ubuntu

The package for libbz2.so.1 is libbz2-1.0. You can check this with the command:

apt-file search libbz2.so.1

Sample output:

% apt-file search libbz2.so.1 
libbz2-1.0: /lib/x86_64-linux-gnu/libbz2.so.1
libbz2-1.0: /lib/x86_64-linux-gnu/libbz2.so.1.0
libbz2-1.0: /lib/x86_64-linux-gnu/libbz2.so.1.0.4

Therefore install the package for 32-bit with the command:

sudo apt-get install libbz2-1.0:i386

The library ia32-libs is no longer in the repositories. Check here.

Are you still trying to do this? I (after much frustration) installed LabVIEW 8.5 32-bit on my new 64-bit Linux Mint Debian Edition 2 (LMDE2) machine today. Should be similar for Ubuntu.

You probably already did, but for those who don't know the first thing to do is set up multiarch (the ability to run 32-bit programs on 64-bit machines):

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get upgrade

This broke my Cinnamon; but running the update manager fixed it again. That's a LMDE specific problem; I don't think you need to worry about that. Then install some dependencies. bzip2 includes the libbz2.so.1 you were looking for, and (as already mentioned) lib32z1 replaces ia32-libs:

sudo apt-get install lib32z1
sudo apt-get install bzip2:i386

The LabVIEW installer looks in an unusual place for a file, so we make a link to it so it can find it:

sudo ln -s /lib/x86_64-linux-gnu/libc.so.6 /lib/libc.so.6

Now the LabVIEW installer will run, but LabVIEW won't start after the installer finishes because it needs libGL.so.1. This is where my method is a bit iffy and there is certainly a better method ... but this is how I did it:

sudo apt-get install libgl1-fglrx-glx:i386 

This installed the libGL.so.1. It also killed my MDM (graphical login). So I dropped to a tty, made a copy of libGL.so.1, and then

sudo apt-get remove libgl1-fglrx-glx:i386
sudo cp libGL.so.1 /usr/lib

After that, everything worked :). I hope this helps you or someone.
