Re: [Caml-list] Using C threads

[Niki Yoshiuchi <aplusbi@gmail.com>]

My main program is in OCaml.  Thread.thread_initialize is only called
if you actually use the module in question.  I tested this with some
simple code:

main.ml: (ocamlc -c main.ml)

let _ = Printf.printf "Main\n"

test.ml: (ocamlc -c test.ml)

let _ = Printf.printf "Test\n"

test2.ml: (ocamlc -o test2.cma -a test2.ml)

let _ Printf.printf "Test2\n"

ocamlc test2.cma test.cmo main.cmo
./a.out
Test
Main

"Test2" never gets printed.
