[Caml-list] Creating an OPAM package that wraps c functions that can be used in a non-custom utop

[<mads379@gmail.com>]

I have a small OCaml library that wraps a couple of C functions that I wrote.
I'm able to compile the project to a .cmx?a file just fine using ocamlbuild.

I have the following files

src
    geolocalisation_c.c
    geolocalisation.ml
    geolocalisation.mllib

I want to be able to play around with my code in a top-level, and I'm able to
do this just fine with the following series of commands.

    ocamlbuild src/geolocalisation_c.o
    ocamlbuild -pkgs ounit src/geolocalisation.cma
    ocamlmktop -custom -cclib -lGeoIp _build/src/geolocalisation_c.o _build/
src/geolocalisation.cma -o myutop

To verify that it works I run

    ./myutop -I _build/src/
    #load "geolocalisation.cmo";;
    Geolocalisation.create_context;;

and I get the correct type-signature printed in the top-level.

The next thing I want to do is create an OPAM package for it that my co-
workers and I can use. My question is, will I be able to create the package in
such a way that the library can be loaded into utop using topfind so we don't
have to build a custom top-level in the projects that use this library?
Basically I would like the users of the library to be unaware that it invokes
external c functions.

If it is possible, do you have any pointers to where I might find some
information about how to do it?

Cheers,
Mads
