Viewing library dependencies with ldd(1)

Viewing library dependencies with ldd(1)

The ldd command works on 64-bit executables or shared libraries.

The ldd(1) command lists the dynamic dependencies of executable files or shared libraries. ldd displays verbose information about dynamic dependencies and symbol references:

Executable All shared libraries that would be loaded as a result of executing the file.

Shared library All shared libraries that would be loaded as a result of loading the library.

ldd uses the same algorithm as the dynamic loader

(/usr/lib/pa20_64/dld.sl) to locate the shared libraries.

ldd does not list shared libraries explicitly loaded using dlopen(3X) or shl_load(3X).

ldd prints the record of shared library path names to stdout. It prints the optional list of symbol resolution problems to stderr.

To do this

Use the

option

 

 

 

Check reference to data symbols.

-d

 

 

Check reference to data and code symbols.

-r

 

 

Displays the search path used to locate the shared

-s

libraries.

 

 

 

Display all dependency relationships.

-v

 

 

Examples

By default, ldd prints simple dynamic path information, including the dependencies recorded in the executable (or the shared library) followed by the physical location where the dynamic loader finds these libraries.
