The
ldd
utility displays all shared objects that are needed to run the given program or
to load the given shared object.
Contrary to
nm(1),
the list includes
"indirect"
dependencies that are the result of needed shared objects which themselves
depend on yet other shared objects.
Zero, one or two
-f
options may be given.
The argument is a format string passed to
rtld(1)
and allows customization of
Ns
output.
If one is given, it sets
LD_TRACE_LOADED_OBJECTS_FMT1.
If two are given, they set
LD_TRACE_LOADED_OBJECTS_FMT1
and
LD_TRACE_LOADED_OBJECTS_FMT2,
respectively.
See
rtld(1)
for details, including a list of recognized conversion characters.
The
-a
option displays the list of all objects that are needed by each loaded
object.
This option does not work with
a.out(5)
binaries.
The
-v
option displays a verbose listing of the dynamic linking headers
encoded in the executable.
See the source code and include
files for the definitive meaning of all the fields.
