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

There is a great article about this exact problem here:

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:
