Subject: [Caml-list] problem with Printf.printf when linking in bytecode interpreter to
 C app

Precedence: bulk

I've linked the ocaml runtime into my application:
this is my ocaml.ml:
let _ = Printf.printf "ocaml inited\n"

let foo () = Printf.printf "this works\n"


let rec fib n = if n < 2 then 1 else fib(n-1) + fib(n-2)

let _ = Callback.register "foo" foo

let _ = Callback.register "fib" fib


This is the relevant C code:
    printf("calling caml_startup\n");
    caml_startup(argv);
    callback(*caml_named_value("foo"), Val_unit);
    result = Int_val(callback(*caml_named_value("fib"), Val_int(6)));
    printf("the result of fib is %d\n", result);


The only output I get is:
calling caml_startup
the result of fib is 13

Why don't the Printf.printf statements output anything?


Thanks.
