ldd - Shows run-time DSO dependencies
ldd [-D] [-a rldargs] object
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.
Sets the environment variable _RLD_ARGS to the string rldargs
before executing the runtime linker (rld).
-D Does not on delay-loaded DSOs.
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.
