them to locate shared objects at runtime. The @code{-rpath} option is
also used when locating shared objects which are needed by shared
objects explicitly included in the link; see the description of the
@code{-rpath-link} option.
The @code{-rpath} option may also be used on SunOS. By default, on
SunOS, the linker will form a runtime search patch out of all the
@code{-L} options it is given. If a @code{rpath} option is used, the
@code{-L} options it is given. If a @code{-rpath} option is used, the
runtime search path will be formed exclusively using the @code{-rpath}
options, ignoring the @code{-L} options. This can be useful when using
gcc, which adds many @code{-L} options which may be on NFS mounted
filesystems.

@item -rpath-link @var{DIR}
When using ELF or SunOS, one shared library may require another. This
happens when an @code{ld -shared} link includes a shared library as one
of the input files.
When the linker encounters such a dependency when doing a non-shared,
non-relocateable link, it will automatically try to locate the required
shared library and include it in the link, if it is not included
explicitly. In such a case, the @code{-rpath-link} option
specifies the first set of directories to search. The
@code{-rpath-link} option may specify a sequence of directory names
either by specifying a list of names separated by colons, or by
appearing multiple times.
The linker uses the following search paths to locate required shared
libraries.
@enumerate
@item
Any directories specified by @code{-rpath-link} options.
@item
Any directories specified by @code{-rpath} options. The difference
between @code{-rpath} and @code{-rpath-link} is that directories
specified by @code{-rpath} options are included in the executable and
used at runtime, whereas the @code{-rpath-link} option is only effective
at link time.
@item
On SunOS, if the @code{-rpath} option was not used, search any
directories specified using @code{-L} options.
@item
For a native linker, the contents of the environment variable
@code{LD_LIBRARY_PATH}.
@item
The default directories, normally @file{/lib} and @file{/usr/lib}.
@end enumerate
If the required shared library is not found, the linker will issue a
warning and continue with the link.
