On the other hand, -undefined dynamic_lookup is already deprecated on
all darwin platforms except for macOS,
Aha, that's interesting.
so it's good time to get rid of
the option. ld64 also provides -bundle_loader <executable> option,
which allows to resolve symbols defined in the executable symtab while
linking. It behaves almost the same with -undefined dynamic_lookup,
but it makes the following changes:
Require that unresolved symbols among input objects must be defined
in the executable.
I'm not sure this is true for elns. What if a function in a.eln calls a
function F in b.eln? In that case, F wouldn't be defined in the
executable.
Lazy symbol binding will lookup only the symtab of the bundle loader
executable. (-undefined dynamic_lookup lookups all symtab as flat
namespace)
Not sure what he's saying...
