[Caml-list] ctypes and oasis

["Christoph Höger" <christoph.hoeger@tu-berlin.de>]

Dear all,

I attempt to compile an oasis project structured like this:

library Bar
  Modules: Wrapper
  CSources: bar.c
  BuildDepends:     ctypes.foreign
  CCLib:            -lfoo


Essentially, bar is both an extension of foo and a binding of this
extension for OCaml (using ctypes).

The "extension" point is problematic. While I can build this lib just
fine, the ctype bindings to the extension methods in bar.c are not found
at runtime using Dl:

Dl.DL_error("./main.native: undefined symbol: some_bar")

This is to be expected, as there is no dynamic library for bar.

So how do I solve this?

Is there some way to tell oasis to build a shared library from the
csources (and link it to all depending artifacts)?

thanks,

Christoph
