NAME

ldd - list dynamic dependencies of executable ®les or shared libraries

SYNOPSIS

ldd [-b] [-d] [-r] [-s] [-v] ®lename...

DESCRIPTION

ldd is a command that can list the dynamic dependencies of incomplete executable ®les or shared libraries.

ldd lists verbose information about dynamic dependencies and symbol references. If the object ®le is an executable ®le, ldd lists all shared libraries that would be loaded as a result of executing the ®le. If it is a shared library, ldd lists 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/dld.sl and /usr/lib/pa20_64/dld.sl) to locate the shared libraries at runtime. See "Dynamic Path List" in dld.sl(5) for more information.

Options

ldd recognizes the following options:

-bPA32-only. Used in conjunction with -dand/or -rto force dld.sl to bind all dependent libraries and report unsats. By default, the smartbind mechanism in dld.sl only binds libraries whose symbols are explicitly referenced.

-dCheck reference to data symbols.

-rCheck reference to data and code symbols.

-sDisplay the search path used to locate the shared libraries. -vDisplay all dependency relationships.

EXTERNAL INFLUENCES

Environment Variables

ldd uses the following environment variables to locate shared libraries.

LD_LIBRARY_PATH

64-bit mode: A colon-separated list of path names which de®nes the search path for shared libraries at runtime. See "Dynamic Path List" in dld.sl(5) for more information.

SHLIB_PATH

A colon-separated list of path names which de®nes the search path for shared libraries at runtime. See "Dynamic Path List" in dld.sl(5) for more information.

The following internationalization variables affect the execution of ldd:

LANG

Determines the locale category for native language, local customs and coded character set in the absence of LC_ALL and other LC_* environment variables. If LANG is not speci®ed or is set to the empty string, a default of C (see lang(5)) is used instead of LANG.

LC_ALL

Determines the values for all locale categories and has precedence over LANG and other LC_* environment variables.

LC_MESSAGES

Determines the locale that should be used to affect the format and contents of diagnostic messages written to standard error.

LC_NUMERIC

Determines the locale category for numeric formatting.

LC_CTYPE

Determines the locale category for character handling functions.

NLSPATH

Determines the location of message catalogs for the processing of LC_MESSAGES .

If any internationalization variable contains an invalid setting, ldd behaves as if all internationalization variables are set to C. See environ(5).
