However, the documentation seems to imply that the behaviour of
whole-archive should happen on all platforms, for all convenience
libraries.
e.g.
— Variable: *whole_archive_flag_spec*
Compiler flag to generate shared objects from convenience
archives.
If whole_archive_flag_spec is empty, as it is on darwin for more
recent versions of libtool then the convenience archive will be
unpacked using lipo/ar and the objects will be added to the link
line.
I haven't been able to reproduce this behaviour when building
binaries for either libtool-1.5.22 or current CVS libtool (although
it does unpack the archive when building installable libraries from
convenience libraries).
For binaries, convenience archives are treated as normal libraries
and are linked as normal, when building shared libraries, they are
extracted, as you note.
Whether this is in itself a bug is debatable, and quite likely has
already been debated on this, or the general libtool list. I suggest
that you stop using convenience archives in this case and use
ordinary objects instead. I believe, but haven't tried, using the -
dlopen flag to point to the libraries that the executable will dlopen
will also cause the required symbols to be included in the executable
(because they will be referenced in the generated object containing
the libraries symbols).
Hope this helps,
Peter
