Cannot execute binary file on Ubuntu ./webupdater

Question

1. I have downloaded "precompiled sample for GTK2" from here http://wxcode.sourceforge.net/components/webupdate/ on Ubuntu machine.
2. I extracted this, and it creates a folders "simple/v1.0.0" which contains executable file "webupdater".
3. When I run this command on terminal s5@s5-desktop:~/ble/simple/v1.0.0$ ./webupdater -bash: ./webupdater: cannot execute binary file it says can not execute binary file.

configuration of Ubuntu machine is given below.

s5@s5-desktop:~$ uname -a Linux s5-desktop 3.5.0-23-generic #35~precise1-Ubuntu SMP Fri Jan 25 17:15:33 UTC 2013 i686 i686 i386 GNU/Linux

Please help, Why this problem is coming. Thanks and Regards Brajesh...

Answer 1

Are you running a 32 or 64 bit Ubuntu ? - check tha with the command :

uname -m

EG: "x86_64" is 64 bit, and "i686" is 32 bit.

Run the file command to see what the executable is :

file /bin/ls

I am in Ubuntu 14.10, which no longer has ia32-libs, which used to fix this. I have yet to find a solution to running a binary that is not installed. In my case I am going to have to look at compiling the app on my system, and I will try and feed back to the original developer...

Answer 2

There can be many reasons:

1. Check the file permissions, do chmod 777 webupdater and then try executing again,
2. Check the type of file by executing file webupdater and compare it with your system uname -r , ie wether both are 32-bit, 64-bit or not. the file webupdater output can give you more information.

Answer 3

When I executed file webupdater, it gives output given below

s5@s5-desktop:~/ble/simple/v1.0.0$ file webupdater webupdater: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.4.0, stripped

and Ubuntu system is 32bit
