Cannot run 32-bit apps on 64-bit Linux

Question

I have a very minimal install of Ubuntu 8.04 64-bit.

When I try to run some 32-bit programs, such as my jhead program, I get the message No such file or directory.

I figured it may be a library problem, but when I do:

ldd jhead

instead of a list of libraries it needs, I just get the message not a dynamic application. Same for another old 32-bit app I use.

So it would appear some very important components for running 32 bit apps are not installed. But how do I even determine what these are?

You need to install 32bit userland support. Namely 32 bit versions of ld.so , you'll need more programming specifics though to keep this question open. — Kent Fredric, Apr 09 '09 at 21:06

You will need to install the 32bit library package

ia32-libs - ia32 shared libraries for use on amd64 and ia64 systems

go and execute

sudo aptitude install ia32-libs

After using up an immense amount of Google's computrons, I just found the same thing. And ldd magically works after this command too. – Matthias Wandel Apr 09 '09 at 21:10
In the newest Ubuntu, install `lib32z1` (`apt install lib32z1`). – kenorb Sep 22 '22 at 14:03

Doing ldd ./ might help to see which library dependancies are succesfully resolved.
