We don't.  We sometimes use -module, but then link against that shared
object, as if it was I library.  I meant to do something about this for
some months now, but never got around to it.  It's also needed for NetBSD
with a.out, I believe.  This is exactly the problem you have.  What should
be done, and I even have some patches here which do this, is for each
module, whose functionality also is used for others, is to create a shared
lib, _and_ a module linking against that lib.

Yep, we then would have libdcopserver_bla.so.* which can be linked
against, and dcopserver.so, which can be loaded.  We have a small problem
here, as the library need to have a different basename than the module,
for some architecture, where even modules need to be called lib*.*.  (This
is what the _bla above is for).

Hmm, I really thought, that the various BSDs have patches for exactly this
problem in their ports tree.  At least I got the patches from someone from
NetBSD.

I won't have time till begin next week to work on this.


Ciao,
