NAME    [Toc]    [Back]

     ldd - Shows run-time DSO dependencies

SYNOPSIS    [Toc]    [Back]

     ldd [-D] [-a rldargs] object

IMPLEMENTATION    [Toc]    [Back]

     IRIX systems

DESCRIPTION:
     The runtime dynamic linker	loads the object (an executable	or DSO)	and
     all of the	libraries reporting what libraries were	loaded.	 But does
     not execute the program or	DSO.

     This is to	make it	easy to	detect what libraries are loaded by an
     executable	without	having to run it.

     Options:

     -a	rldargs
	  Sets the environment variable	_RLD_ARGS to the string	rldargs
	  before executing the runtime linker (rld).

     -D	  Does not on delay-loaded DSOs.

NOTES    [Toc]    [Back]

     ldd will not report on libraries opened using dlopen(3C).

     Unless the	-D option is specified,	ldd will report	on delay-loaded
     libraries.	 If the	-D option is not specified, ldd	may show messages
     other than	those it would show during normal execution, since the
     order of DSO loading and symbol resolution	is necessarily different.

     ldd honors	the _RLD*_PATH environment variables for use in	testing	ldd
     and rld.  If the appropriate _RLD*_PATH is	pointing to an rld, not	an
     rld.debug,	ldd will not do	anything useful.

     There is a	-x option used to debug	ldd that is not	normally useful.
