[Caml-list] library dynamic loading ?

["SooHyoung Oh" <shoh@duonix.com>]

Hi!

Is it possible to load library dynamically?

Here are my trials; Did I miss something or is it impossible to load library
dynamically?

(1) First,  I made toplevel system with unix library
    $ ocamlmktop -o unixtop unix.cma

(2) GOOD!!!: It's OK to execute a script
    $ cat fread

    open Unix;;

    let buffer = String.create 100 in

    let fd = openfile "demo.txt" [O_RDONLY] 0 in

    let n = read fd buffer 0 100 in

    let err = write stdout buffer 0 n in

    close fd;;

    $ unixtop fread

    Hello

(3) Fail 1: dynamic load of unix library

    $ ocaml unix.cma fread

    File "/usr/lib/ocaml/threads/unix.cma", line 1, characters 12-13:

    Illegal character (\000)

(4) Fail 2: dynamic load of library

    $ cat fread2

    #load “unix.cma”;;

    ... (same as fread)

    $ ocaml fread2

    The external function `unix_read' is not available
