You use the standard bytecode interpreter, which does not know anything
about your C function, to start your custom executable. Just use
./a.out
to start the program. Actually, you (nearly) never have to call ocamlrun
yourself, the bytecode program contains some nice magic to start up the
right bytecode interpreter for you.
