Are you building your own GNAT or using mine from SF GNUAda? If the
latter, then a couple of points --

(a) you need
   for Library_Options use ("-single_module");

(b) the version I uploaded only has static libraries which will make
it hard to create dynamic ones :-(

I've built gnatlib-shared, but there seem to be some problems on OS X
-- specifically, I have to set DYLD_LIBRARY_PATH to include the GNAT
adalib directory, or I get problems building a program that references
a dylib that references libgnat-2007.dylib or libgnarl-2007.dylib. I
don't think that a standard link uses the dylibs -- this may be what
configure --disable-libada does, of course.

I ended up with libsampleplug.so.0.1.0 as the executable &
libsampleplug.dylib a symlink to it. This gets to the point of
printing

   Using the locator to load the plugin...
      Name            => sampleplug

at which point it stops.

This was of course using the src-linux bodies.
