Re: A proposed patch for undefined_symbol ()

[Koundinya K <knk at dde dot dk>]

Hi hjl,
    Normally when -Bsymbolic is uses when building a shared object (library) ,  the
linker should bind  references to global symbols to their definitions  within the
object, if defintions are available. Normally, since references  to  global
symbols  within  shared objects are not bound until run time, even  if
definitions  are  available,  so that definitions of the same symbol in an
executable or  other  shared  objects  can
override  the  object's  own definition. The linker should issue warnings for
undefined symbols unless there is an option in the Linker to force a fatal error if
any undefined symbols remain  at
 the end of the link. So I feel  we need to have a separate option in the Linker to
address this.

Thanks.
