NAME
       ldd - list dynamic dependencies

SYNOPSIS
       ldd [-d | -r] file

DESCRIPTION
       The ldd command lists the path names of all shared objects that would
       be loaded as a result of executing file.  If file is a valid
       executable but does not require any shared objects, ldd will succeed,
       producing no output.

       ldd may also be used to check the compatibility of file with the
       shared objects it uses.  It does this by optionally printing warnings
       for any unresolved symbol references that would occur if file were
       executed.  Two options govern this mode of ldd:


       -d     Causes ldd to check all references to data objects.

       -r     Causes ldd to check references to both data objects and
              functions.

       Only one of the above options may be given during any single
       invocation of ldd.

DIAGNOSTICS
       ldd prints its record of shared object path names to stdout.  The
       optional list of symbol resolution problems are printed to stderr.
       If file is not an executable file or cannot be opened for reading, a
       non-zero exit status is returned.

SEE ALSO
       cc(1), ld(1).

NOTES
       ldd doesn't list shared objects explicitly attached via dlopen(3X).

       ldd uses the same algorithm as the dynamic linker to locate shared
       objects.
