<taw> how to do md5 in ocaml ?
* taw is rewriting perl code in ocaml now ^_^
<taw> now where is system() call ?
<taw> oh, here it is

<uzdav> Hi again, another module question. :)
<uzdav> If I want to have a module signature in a file by itself, (say myModule.mli) and I want to implement a module using that signature with a different name, how do I get it to find that file?
<uzdav> For example, in file myModule.mli, I have this:
<uzdav> type something
<uzdav> val b : something
<uzdav> val v : something -> int
<uzdav> in another file foo.ml, I have this:
<uzdav> module Foo : MyModule = struct
<uzdav> type something = int
<uzdav> let b = 5
<uzdav> let v x = b
<uzdav> end
<uzdav>
<uzdav>
<uzdav> when I compile, it says unbound module MyModule.
<uzdav> What must be done so that I can have an arbitrary interface in its own file, with an implementation of that module in an arbitrarily-named .ml file?
<uzdav> (I have one interface with several implementations I'd like to have, and am trying to get this to work in one case before I continue.)

<whee> someone want to clue me in as to what the characters '+' and '-' do when used in a variant type declaration?
<whee> nevermind, found it
<whee> still trying to find a good example of when to use polymorphic variants :\

<jlamar> Is there an existing lib for MP3 and/or MOD decompression for ocaml?
graydon has quit ["xchat exiting.."]
<jlamar> Guess I should check the hump
<whee> I don't recall seeing one
<jlamar> Hmm..maybe I'll port some C one
<jlamar> err...bind
<whee> gah I'm going nuts trying to figure out how to use = < and > with polymorphic variants and the type definition
<whee> unless those are only for constraints, which makes a lot more sense. heh

<mellum> Is there something like assert() in ocaml?
taw has joined #ocaml
<mellum> Looks like there is, and it's called "assert". That was too easy :)
<taw> is it possible to make shared library in ocaml that will be accessed from c code ?
<Segora> hmm. interesting question... let's see if ocamlopt can produce position independent and reentrant code.
<taw> who cares about multithreading
<taw> i will be happy if single-thread will work
<Segora> that has nothing to do with multithreading
<taw> oh
<Segora> the code has to be position independent because it may be mapped to different addresses in different processes
<taw> that part is true
<taw> the second is not very true
<Segora> unfortunately, I didn't find an option to produce PIC
<Segora> ah, you're right about the second part
<Segora> silly me
<Segora> you could produce shared libraries without PIC which shoudl work most of the time by specifying a fixed address in the ELF header. but that's an ugly hack and it won't always work.
docelic has quit ["Client Exiting"]
<taw> hmm
<taw> -custom
<taw> Link in ``custom runtime'' mode. In the default linking mode, the linker produces bytecode that is
<taw> intended to be executed with the shared runtime system, ocamlrun(1). In the custom runtime mode,
<taw> the linker produces an output file that contains both the runtime system and the bytecode for the
<taw> program. The resulting file is larger, but it can be executed directly, even if the ocamlrun(1)
<taw> command is not installed. Moreover, the ``custom runtime'' mode enables linking Caml code with
<taw> user-defined C functions.
<taw> -ccopt Pass the given option to the C compiler and linker, when linking in ``custom runtime'' mode (see
<taw> the -custom option). For instance, -ccopt -L dir causes the C linker to search for C libraries in
<taw> directory dir.
<Segora> hmm
<taw> can i pass -PIC to -ccopt ?
<Segora> maybe, didn't try so far
<Segora> give it a try

<taw> mmm, my swig generates bogus c code for linking to ocaml
