I am trying to run a package that is precompiled (supposedly for 'linux64') but get the following error message:

t.kuilman@steroid:~/Peeper/bin/netchop-3.1/bin$ ./netChop -bash: ./netChop: cannot execute binary file: Exec format error 

I checked how this file is compiled (see below) and it turns out to be an ELF 64-bit LSB executable.

t.kuilman@steroid:~/Peeper/bin/netchop-3.1/bin$ file ./netChop ./netChop: ELF 64-bit LSB executable, no machine, version 1 (SYSV), statically linked, for GNU/Linux 2.4.1, for SuSE 9.1, stripped t.kuilman@steroid:~/Peeper/bin/netchop-3.1/bin$ ldd ./netChop not a dynamic executable t.kuilman@steroid:~/Peeper/bin/netchop-3.1/bin$ uname -a Linux steroid 3.13.0-76-generic #120-Ubuntu SMP Mon Jan 18 15:59:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux 

How can I get this file to run on my system (Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-76-generic x86_64))?

  • There seems to be something very strange about that executable. Can you upload it somewhere, or provide a hex dump of the first 512 bytes or so? Commented Jan 29, 2016 at 16:36

    Could you bring up SuSE 9.1 64-bit in a VM (VirtualBox) and try it there? Commented Jan 29, 2016 at 16:39

This executable is likely either corrupt, or built in some non-standard way:

ELF 64-bit LSB executable, no machine, version 1 (SYSV) ... 

A normal statically linked Linux executable should look like this:

ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux) 

Note machine ("no machine" vs. "x86-64") and OS ABI ("SYSV" vs. "GNU/Linux") differences.

In any case, there is nothing you can do about it, other than complain to the producer of the package.
