[SOLVED] Copied my app from one Linux to a second on VM: bash cannot exec binary file

kathbeau · 03-13-2015, 09:37 AM

First, I am a Linux newbie (only a few months of experience).

My development machine is a 64-bit running Debian 7

Code:

on 64-bit dev machine
uname -a
Linux mix 3.16-0.bpo.2-amd64 #1 SMP Debian 3.16.3-2~bpo70+1 (2014-09-21) x86_64 GNU/Linux

I have a wxWidgets app that I copied to a Kali Linux environment running in 32-bit VMware Player on my Windows 7-64 machine.

Code:

on 32-bit VM machine
uname -a
Linux kali 3.12-kalil-486 #1 Debian 3.12.6-2kalil (2014-01-06) i686 GNU/Linux

I build the app using Code::Blocks, which as far as I know can build only 32-bit apps.

When I copy my app from dev to VM, however, and try to run it, I get this error:

Code:

bash: ./MyApp: cannot execute binary file

I have performed searches for this error message, but have not found one that seems to address my situation.

I'm hoping this will sound like a "newbie" question, and that somebody can steer me towards a solution.

Thanks for your help,
Kathleen

Binary compiled to run under 64bit cpu cannot run on a 32bit cpu. Vice Versa may be possible but depends.

You can check which arch a binary is by running:

Code:

file binary-name

Thank you! The file command reveals that it is, indeed, a 64-bit app.

I'll take this up in the Code::Blocks forum to find out how I can build a 32-bit app on my 64-bit dev machine.
