ldd - print shared library dependencies
ldd [OPTION]... FILE...
ldd prints the shared libraries required by each program or shared library
specified on the command line.
--version
Print the version number of ldd.
-v --verbose
Print all information, including, for example, symbol versioning
information.
-u --unused
Print unused direct dependencies. (Since glibc 2.3.4.)
-d --data-relocs
Perform relocations and report any missing objects (ELF only).
-r --function-relocs
Perform relocations for both data objects and functions, and report any
missing objects or functions (ELF only).
--help Usage information.
The standard version of ldd comes with glibc2. Libc5 came with an older
version, still present on some systems. The long options are not supported by
the libc5 version. On the other hand, the glibc2 version does not support -V
and only has the equivalent --version.
The libc5 version of this program will use the name of a library given on the
command line as-is when it contains a '/'; otherwise it searches for the
library in the standard locations. To run it on a shared library in the
current directory, prefix the name with "./".
ldd does not work on a.out shared libraries.
ldd does not work with some extremely old a.out programs which were built
before ldd support was added to the compiler releases. If you use ldd on one
of these programs, the program will attempt to run with argc = 0 and the
results will be unpredictable.
ld.so(8), ldconfig(8)
