Q:

How to run a ghc compiled binary on other machines?

This post is really informative on what I'm trying to achieve.
I produced a simple HelloUnix binary.
$ echo 'main = putStrLn "Hello Unix"' > HelloUnix.hs
$ ghc -static --make HelloUnix.hs

Which created a HelloUnix binary, I was hoping  with the -static flag everything is bundled up inside the binary so that all is needed to run the binary was the file itself.  I transferred the binary to another unix machine, made sure that the file has the correct access privilege via chmod. Ran the binary but this error showed up 
bash: ./HelloUnix: cannot execute binary file

Any ideas on how to debug this?
EDIT:
I'm currently trying to developing a distributed system, thus was hoping to just distribute the binary to target machines.  I need a way to run the binary regardless of witch machine it's running on, that's the target anyways.

EDIT3:
I'm now compiling the code in machine 2 and trying to run the binary in machine 1. I assume because both of them are i386 so the binary should be able to run on the other machine. However I'm getting this error:
HelloUnix: Cannot find /lib/ld-linux.so.2
Killed

I think this is telling me that a library (ld-linux.so.2) the binary depend on (dynamic linking maybe?) is not in my target machine.  I'm a little bit confused on what did the flag -static do?  I assumed with the flag, ALL dependencies would be bundled up in the binary.  What would be the best way to make Haskell code portable?

A:

If you are targeting the same architecture, it should work without any fuss (so long as necessary data files are also distributed).
If you are targeting a different architecture, as in your case, you need to cross-compile for the target platform; see the GHC wiki.
