Linking order with Ocamlbuild

Linking order with Ocamlbuild

[Dario Teixeira]

Hi,

I am using the custom myocamlbuild.ml for ocamlfind support that is listed
in the Ocamlbuild wiki [1].  I would like to separate the list of packages
used for compilation and for linking; and in the latter case I would like
to provide an explicit linking order.  This is what I'm currently listing
in _tags:

<**/main.native>: pkg_a, pkg_b, pkg_c
<**/*.ml>: pkg_b, pkg_c

Which is neither particularly pretty nor actually working.  Namely, during
the linking stage, ocamlbuild is invoking "-package b -package a".  This is
in the wrong order, and different from the one I specified.  Is there any
straightforward way to fix it?

Thanks for your thoughts!
Cheers,
Dario

As far as I observed ocamlbuild preserves the same order of libraries at the linking stage
that was used when introducing those libraries in myocamlbuild.ml (namely with ocaml_lib).
So try to sort the output of find_packages as you need.
