If you want to have a two-level image (and don't get an answer from
pogma explaining how to talk to libtool in its native language),
you can replace the "-module -shared" simply by "-bundle -undefined
dynamic_lookup -bind_at_load".
For the curious.
GNU libtool, version 1.5.4 and later will notice if
MACOSX_DEPLOYMENT_TARGET is set at configure time, and, if so, will
use -undefined dynamic_lookup when linking shared libraries with
undefined symbols. This means that installed libtool scripts (/usr/
bin/glibtool, /sw/bin/glibtool) will always attempt to do this, so
you should always set MACOSX_DEPLOYMENT_TARGET to the value that gnu
libtool saw when it was configured when you use it for linking.
If there exists on the libtool line a '-no-undefined' flag, then no
flags relating to undefined symbols will be passed to the compiler
driver.
GNU libtool will behave differently should libtool-2.0 ever be
released (there will be libfoo.dylib and libfoo.X.dylib, removing a
redundant symlink, and libraries will, by default, link -
single_module). The behavior with respect to undefined symbols should
be the same for future releases though.
Hope that this helps more than confuses,
Peter
