Compiling pycaml shared library

Compiling pycaml shared library

[Grant Monroe]

Hello All,
I'm trying to figure out how to compile a simple shared library (.so)
using pycaml that I can load from the python interpreter. I have a
single .ml file who's contents are as follows:


open Pycaml

let foo_bar_print = pywrap_closure (fun x -> print_endline "hi" ; pynone ()) ;;
let sd = pyimport_getmoduledict () ;;
let mx = pymodule_new "CamlModule" ;;
let cd = pydict_new () ;;
let cx = pyclass_new (pynull (), cd, pystring_fromstring "CamlClass") ;;
let cmx = pymethod_new (foo_bar_print,(pynull ()),cx) ;;
let _ = pydict_setitemstring (cd, "CamlMethod", cmx) ;;
let _ = pydict_setitemstring (pymodule_getdict mx, "CamlClass", cx) ;;
let _ = pydict_setitemstring (sd, "CamlModule", mx) ;;


I'm new to ocaml so basically I want to know what commands to run with
which flags and what libraries need to be linked to and how. Any help
would be appreciated.

P.S. - I tried sending the project creator a message, but the email
address listed on the page seems to have expired.

I'm not familiar with pycaml, but mod_caml compiles itself as a .so
file so it can be loaded into Apache.  It is only possible with
bytecode (for the moment at least), and the process was very
complicated to figure out.  I suggest you start by examining the
makefile:

http://cvs.savannah.nongnu.org/viewcvs/modcaml/Makefile?rev=1.68&root=modcaml&view=markup

I also had to to this task. So I wrote my own library, like py2caml (named
py2caml) - just
to write python extentions on ocaml (without C code).
Unlike pycaml, it can handle multi-threaded apps, safe for user errors in
python or caml code etc.

If you interested I can upload the library to sourceforge, and/or answer
your questions.

Hello Vsevolod,
That would be great. It appears that the pycaml project is no longer
being maintained so py2caml might just fill the void.
