Can't run example program after standard apt-get install

[runizgozilla]

I've just done a standard

Code: [Select]

sudo apt-get install libsfml-devon my linux (Xubuntu) system, and when I try running the program I get this:

Code: [Select]

me@my-laptop:~/Documents/cpp$ ./sfml_test.out
bash: ./sfml_test.out: cannot execute binary file: Exec format error

The result of a "file <filename>" command is this:

Code: [Select]

sfml_test.out: ELF 32-bit LSB  relocatable, Intel 80386, version 1 (GNU/Linux), not stripped

I should mention the code is the example code found here:

This question just quintupled in embarrassment as I've just now realized I didn't read the instructions all the way through.  This is typical of me I'm afraid and I apologize.
