Solution to the "No such file or directory" prompt when executing executable files in Linux

Recently, when I was using the Linux operating system to execute an executable file, a prompt "No such file or directory" appeared, which made me very confused.

./tshrf

bash: ./tshref: No such file or directory

Check the file information and you can see that the file exists and is executable.

-rwxr-xr-x 1 yuan yuan 20581 April 29 2004 tshref

After consulting the information, the reason is that the system bitness does not match the lib library bitness required by the executable file.

Use the uname command to print system information and find that the system is a 64-bit system

uname -a

Linux yuan-vm 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Use the file command to view the file information and find that it is a 32-bit executable file.

file ./tshref

./tshref: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), 
dynamically linked (uses shared libs), for GNU/Linux 2.2.5, not stripped

To run 32-bit programs on a 64-bit system, you need to install the 32-bit lib library.

For Ubuntu users, you can use the following command to install it.

sudo apt-get install ia32-libs

Reading package lists... Done
Building dependency tree    
Reading state information... Done
Package ia32-libs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
 lib32z1 lib32ncurses5 lib32bz2-1.0

The required library may not be found during the process, but there will be several alternative packages. Choose to install one of them.

sudo apt-get install lib32bz2-1.0
lib32bz2-1.0

Then you can run the previous executable file normally.

There may be other reasons for this problem, such as text encoding format problems. This article only proposes a solution. Readers who encounter the same problem should analyze the specific problem.
