ldd(1) ldd(1)

ldd returns zero when the operation is successful. A non-zero return code indicates that an error

occurred.

EXAMPLES

By default

ldd prints a simple dynamic path information. This consists of the dependencies recorded in

the executable (or the shared library) followed by the physical location where these libraries are found.

ldd a.out

./libx.so => ./libx.so

libc.so => /usr/lib/hpux32/libc.so.1

libdl.so => /usr/lib/hpux32/libdl.so.1

The -v option causes ldd to print dependency relationship along with the dynamic path information.

ldd -v a.out

find library=./libx.so; required by a.out

./libx.so => ./libx.so

find library=libc.so; required by a.out

libc.so => /usr/lib/hpux32/libc.so.1

find library=libdl.so; required by /usr/lib/hpux32/libc.so.1

libdl.so => /usr/lib/hpux32/libdl.so..1

The -r option to ldd causes it to analyze all symbol references and print information about unsatisﬁed

code and data symbols.

ldd -r a.out

./libx.so => ./libx.so

libc.so => /usr/lib/hpux32/libc.so.1

libdl.so => /usr/lib/hpux32/libdl.so.1

symbol not found: val1 (./libx.so)

symbol not found: count (./libx.so)

symbol not found: func1 (./libx.so)

WARNINGS

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