Executing 32 bit code under Ubundu 64 bit installation error- No such file or directory

Question

Why I am getting "No such file or directory" error when I am running 32 bit executable in a 64 bit Ubundu installation?

What I expect is : A message that "file is invalid", OR the 32 bit code get run correctly.

Details below:

user@user-desktop:~/32_64$ ls
myfile32bit  myfile64bit

user@user-desktop:~/32_64$ file myfile32bit
myfile32bit: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped

user@user-desktop:~/32_64$ file myfile64bit
myfile64bit: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped

user@user-desktop:~/32_64$ ls -l

-rwxrwxrwx 1 user user  146785 2011-10-22 12:46 myfile64bit

user@user-desktop:~/32_64$ ./myfile64bit

user@user-desktop:~/32_64$ ./myfile32bit

There is a great article about this exact problem here:

Answer 2

Due to the march of time the answer marked as correct no longer works. As of release 13 there no longer exists an ia32-libs package. Instead you must install the following:

lib32z1 lib32ncurses5 lib32bz2-1.0

This resolved the issue for me with release 14.

The following link worked for me. I had similar problem with my Ubuntu 11.10 64 bit, when I tried to execute 32 bit eclipse it prompted me "No such file or directory". Follow this link:
