Hi,

I'm having serious problems with ocamlc -output-obj.

It seems if I create a global variable, the interpreter won't run (it
gets into caml_interprete, but I don't know where it goes wrong once
in that function).

Without any globals present, it runs fine.

let table =3D Hashtbl.create 8;;

Hashtbl.add table 42 "hello world";;

the above code, as simple as it is, causes things to break. Remove it,
and it'll run.

I experience the same problems when linking against Bigarray library,
and having a global value in my Console module.

The only custom parts in my ocaml environment are now just
libcamlrun.a, providing stub functions that return errors/raise
exceptions for functions I don't want/need to support.

My makefile is:

CFLAGS=3D-DCAML_NAME_SPACE -O -fno-defer-pop -ffreestanding -I
../include -I ../byterun -I ../ocaml/lib/ocaml -nostdlib -nostartfiles
-nostdinc

Someone got half a clue on this?

Kindest Regards,

Jonathan
