I'm getting "Error: Unbound value Multiset.of_list" when I run my program with "ocaml ab.ml". multiset.mli and multiset.ml are in the same directory as ab.ml, and of_list is part of the module specification, so I would (naively) expect ocaml to find the module & the function. What am I missing? Do I need to somehow add "." to ocaml's include path, and if so, how do I do that? Googling for "ocaml include-path" wasn't helpful.

<adrien>
Skolem: did you compile the multiset.ml file?
<adrien>
also, 'ocaml' will only run your program through the toplevel, if you want to compile, you'll have to use 'ocamlc' instead
ztfw has joined #ocaml
<adrien>
and last point, you need to put 'multiset.cmo' on the command-line
ikaros has joined #ocaml
<Skolem>
adrien: I ran ocamlopt -c multiset.ml which created multiset.cmi
<Skolem>
How do I get the cmo?
<julm>
ocamlc -c
<adrien>
you use 'ocamlc' XOR 'ocamlopt', you can't mix the output of both (except for the .cmi)
<adrien>
so, if you want a .cmo, use ocamlc as julm said
<adrien>
ocamlc -> bytecode, .cmo and .cma files
<adrien>
ocamlopt -> native code, .cmx and .cmxa files
<Skolem>
Beautiful, OK, I think that fixed it.
<Skolem>
I'm following allong with this, and when I try the "Set.Make" examples, I get: "Error: Unbound constructor Set.Make". What do I have to do to "load" the Set.Module in the toplevel?
<Skolem>
Oh, wait. TYpo. Sorry for the noise, it's working.

I'm sure this is an annoyingly easy problem, but I'm just starting out and I've put off learning ocaml long enough, so I'll bother you guys with a few more questions. I'm tryingto use multiset.ml from http://web.archive.org/web/*/http://lamp.epfl.ch/~sbriais/caml/multiset.tgz (Jun 07, 2004 version). By the way, I welcome references to a more current implementation of a multiset data structure in ocaml. Anyway...
avsm has joined #ocaml
<Skolem>
I compiled multiset.ml as above, and have a file test.ml which contains two lines: "module String_set = Set.Make (String);;" and "module Region_set = Multiset.Make (String);;". When I run "ocaml multiset.cmo test.ml", I get: "Error: Unbound module Multiset.Make"
<Skolem>
SO it's failing on the Multiset make (I gather module names are equal to the file name with the first letter capitalized?), not on the Set.Make.
<Skolem>
I think my syntax is OK, because I copied the 2nd line from the first and just replaced Set with Multiset. Maybe there's something wrong in the implementation of the multiset, but I doubt it, it seems like people wer using it for a hile there.
<Skolem>
Anyway, I want a multiset, so if someone wants to help me get the "hello wold" multiset working, that'd be awesome. If not, I'll keep bumbling along and figure it out eventually.

<adrien>
Skolem: it's working for me... maybe try to remove the .cm* files and try again?
<Skolem>
Ok, one sec.
<Skolem>
So, first question. When I run, "ocamlc -c multiset.ml", it says, "Error: Could not find the .cmi file for interface multiset.mli". What does that even mean?
<Skolem>
(I feel like the actual programming will be simpler once I get these framework/library/compilation issues sorted out, but I may be mistaken...)
<Skolem>
For the record, I've had spectacularly poor results when googling for these error messages, by the way. As compared to when I try the same thing with Perl or C. Luckily you guys are helpful, but I'd rather let google answer the boring questions and save the interesting ones for here.
<adrien>
ah, maybe it hadn't created the .cmo file?
<adrien>
if you have a A.mli file in the same folder as A.ml, you need to 'compile' it first: ocamlc -c A.mli
<adrien>
it'll create a .cmi file
<Skolem>
I have no idea... When I google for (ocaml cmi mli) the top hit is "The Structure of OCaml Programs". Oh, that looks helpful. Unfortunately the string "cmi" occurs just once on that page, and it's in the line "/usr/lib/ocaml/3.08/graphics.cmi". Gah!
enthymeme has quit [Quit: rcirc on GNU Emacs 23.1.1]
<Skolem>
adrien: Ah! That worked. Ok, moving on...
<adrien>
:-)
<adrien>
googling for that shouldn't be that easy if you don't already know the answer unfortunately =/
<Skolem>
Now I run "ocaml multiset.cmo test.ml" and it works! Hooray!
<Skolem>
ok, now to get down to some coding. *rubs hands gleefully*
<adrien>

I want to make a set in which each element is a list of integers. When I run this simple program, "type intlist = List of int;; module IntList_set = Set.Make (struct type t = intlist let compare = compare end);; let x = IntList_set.add [1;2;3]", I get "Error: This expression has type 'a list but an expression was expected of type IntList_set.elt = intlist" It looks like the types align, even in the error message, so what does that me
<f[x]>
List of int is not int list
<adrien>
'List of int' doesn't define a list of int, you want 'int list' instead
<f[x]>
List of int is "isomorphic" to A of int
<Skolem>
Ah. Gotcha.

Suppose I have "module StringSet = Set.Make (String)". How do I declare "stringset" to be the type in which each element is a StringSet?
leino has joined #ocaml
<mfp>
Skolem: type stringset = StringSet.t
<Skolem>
I can write "type stringset = StringSet.t", but then when I type "[StringSet.empty]" into the toplevel, it infers the type to be "StringSet.t = <abstr>", not "stringset".
prince has quit [Ping timeout: 258 seconds]
<mfp>
Skolem: the toplevel sometimes prints the wrong type alias, but there will be no pb as far as typing is concerned
<Skolem>
OK, thanks.
prince has joined #ocaml
<mfp>
in fact, there's no way the toplevel could know that StringSet.empty is to be shown as being of type stringset
<mfp>
OTOH, if you do let a : stringset = StringSet.empty;;
<mfp>
you get # a;; - : stringset = <abstr>
