Re: [Caml-list] The Bytecode Interpreter...

[Jonathan Roewen <jonathan.roewen@gmail.com>]

Hi once again,

Hopefully this'll be my last problem to solve ;-)

I've got ocamlrun + a bytecode app running on the bare metal, finally =)

The following works fine:

print_endline "Hello, World";;

but, the following fails:

Printf.printf "Hello, World\n%!";;

with a print_endline statement before it, not even that gets run, so
it appears to be a problem with loading the bytecode itself.

The bytecode app is created using ocamlc -output-obj, and the .o file
is linked into my kernel. I then call caml_startup(argv), where argv =
{ "" }.

I've also experienced the same problem (appearing to not load/run the
bytecode) when using Scanf & Hashtbl modules (so it's not isolated to
Printf).

What is the bytecode interpreter trying to do? Any clues? ;-) I'm
trying to debug file open calls and things, but nothing appears to
show up, and I don't get any errors printed to stdout/stderr by the
interpreter.
