[Caml-list] Problem native dynlink loading cryptokit

[Maxence Guesdon <Maxence.Guesdon@inria.fr>]

Hello,

I'm trying to dynamically load the cryptokit library in native mode.

Here is a test program:

cat > testload.ml
let _ = Dynlink.allow_unsafe_modules true;;

let load_file file =
  try Dynlink.loadfile (Dynlink.adapt_filename file)
  with Dynlink.Error e ->
      failwith (Dynlink.error_message e)

let () =
  match Array.to_list Sys.argv with
    [] | [_] -> prerr_endline "missing arguments"; exit 1
  | _ :: files -> List.iter load_file files

Compiling with
   ocamlopt -linkall -o testload dynlink.cmxa testload.ml

Then, running
  ./testload  ~/.opam/4.00.1/lib/ocaml/nums.cmxs \
      ~/.opam/4.00.1/lib/ocaml/unix.cmxs \
      ~/.opam/4.00.1/lib/cryptokit/cryptokit.cmxs

gives me the following error:

Fatal error: exception Failure("error loading shared
library: /home/guesdon/.opam/4.00.1/lib/cryptokit/cryptokit.cmxs:
undefined symbol: caml_sha1_init")

Am I doing something wrong ? Or is something missing in cryptokit
build ?

Thanks,

Maxence
