@kindex --allow-shlib-undefined
@kindex --no-allow-shlib-undefined
@item --allow-shlib-undefined
Allow undefined symbols in shared objects even when --no-undefined is
set. The net result will be that undefined symbols in regular objects
will still trigger an error, but undefined symbols in shared objects
will be ignored. The implementation of no_undefined makes the
assumption that the runtime linker will choke on undefined symbols.
However there is at least one system (BeOS) where undefined symbols in
shared libraries is normal since the kernel patches them at load time to
select which function is most appropriate for the current architecture.
I.E. dynamically select an appropriate memset function. Apparently it
is also normal for HPPA shared libraries to have undefined symbols.
@itemx --no-allow-shlib-undefined
Allow (the default) or disallow undefined symbols in shared objects.
The setting of this switch overrides @samp {--no-undefined} where
shared objects are concerned. Thus if @samp {--no-undefined} is set
but @samp {--no-allow-shlib-undefined} is not, the net result will be
that undefined symbols in regular object files will trigger an error,
but undefined symbols in shared objects will be ignored.
The reason that @samp{--allow-shlib-undefined} is the default is that
the shared object being specified at link time may not be the same one
that is available at load time, so the symbols might actually be
resolvable at load time. Plus there are some systems, (eg BeOS) where
undefined symbols in shared libraries is normal since the kernel
patches them at load time to select which function is most appropriate
for the current architecture. eg. to dynamically select an appropriate
memset function. Apparently it is also normal for HPPA shared
libraries to have undefined symbols.
