linking and exporting symbols

[Richard Guenther]

Hi!

First: please CC me, I'm not on this list.

I'm having problems teaching libtool not to throw away objects
from a static library linked to a program that should export
its symbols to dynamically loaded modules.

I.e. I have

  plugins/bla.la  -- static/shared library, with -module and
                     -avoid-version
  libstuff/libstuff.la  -- static library, with -export-dynamic
  main.c  -- links with libstuff.la, with -export-dynamic and -dlopen self

now, loading of bla.la via lt_dlopen fails, as at link time the objects
needed from libstuff.la have been removed (as they are not used by main.c)

Is there any way to prevent the linker/libtool from doing this? Is this
considered a bug (as I added -export-dynamic to both, the library and
the program)? I know I can work around this by providing unresolved
symbols in the main program, but...

Also lt_dlopen of static archives does not work as documented (or maybe
I misparsed it) - the .la files generated contain references to .a files
(but not in dlopen=, but in old_library= -- does this mean I cannot
dlopen it?), but those are not available before installation, instead
I have .lo files.

Thanx, Richard.
