-.SH DESCRIPTION
-.B ldconfig
-creates the necessary links and cache (for use by the run-time linker,
-.IR ld.so )
-to the most recent shared libraries found in the directories specified
-on the command line, in the file
-.IR /etc/ld.so.conf ,
-and in the trusted directories
-.RI ( /usr/lib
-and
-.IR /lib ).
-.B ldconfig
-checks the header and file names of the libraries it encounters when
-determining which versions should have their links updated.
-.B ldconfig
-ignores symbolic links when scanning for libraries.
-.PP
-.B ldconfig
-will attempt to deduce the type of ELF libs (ie. libc5 or libc6/glibc)
-based on what C libs if any the library was linked against, therefore when
-making dynamic libraries, it is wise to explicitly link against libc (use -lc).
-.PP
-Some existing libs do not contain enough information to allow the deduction of
-their type, therefore the
-.IR /etc/ld.so.conf
-file format allows the specification of an expected type. This is
-.B only
-used for those ELF libs which we can not work out. The format
-is like this "dirname=TYPE", where type can be libc4, libc5 or libc6.
-(This syntax also works on the command line). Spaces are
-.B not
-allowed. Also see the
-.B -p
-option.
-.PP
-Directory names containing an
-.B = are no longer legal
-unless they also have an expected type specifier.
-.PP
-.B ldconfig
-should normally be run by the super-user as it may require write
-permission on some root owned directories and files.
-It is normally run automatically at bootup, from /etc/rc, or manually
-whenever new DLL's are installed.
-.SH OPTIONS
-.TP
-.B \-D
-Debug mode.
-Implies
-.B \-N
-and
-.BR \-X .

-Print current version number, the name of each directory as it
-is scanned and any links that are created.
-Overrides quiet mode.
-.TP
-.B \-q
-Quiet mode.
-Don't print warnings.
-.TP
-.B \-n
-Only process directories specified on the command line.
-Don't process the trusted directories
-.RI ( /usr/lib
-and
-.IR /lib )
-nor those specified in
-.IR /etc/ld.so.conf .
-Implies
-.BR \-N .
-.TP
-.B \-N
-Don't rebuild the cache.
-Unless
-.B \-X
-is also specified, links are still updated.
-.TP
-.B \-X
-Don't update links.
-Unless
-.B \-N
-is also specified, the cache is still rebuilt.
-.TP
-.B \-f conf
-Use
-.B conf
-instead of
-.IR /etc/ld.so.conf .
-.TP
-.B \-C cache
-Use
-.B cache
-instead of
-.IR /etc/ld.so.cache .
-.TP
-.B \-r root
-Change to and use
-.B root
-as the root directory.
-.TP
-.B \-l
-Library mode.
-Manually link individual libraries.
-Intended for use by experts only.
-.TP
-.B \-p
-Print the lists of directories and candidate libraries stored in
-the current cache.
-.SH EXAMPLES
-In the bootup file
-.I /etc/rc
-having the line
-.RS
-
-/sbin/ldconfig -v
-
-.RE
-will set up the correct links for the shared binaries and rebuild
-the cache.
-.TP
-On the command line
-.RS
-
-# /sbin/ldconfig -n /lib
-
-.RE
-as root after the installation of a new DLL, will properly update the
-shared library symbolic links in /lib.

-.LP
-.BR ldconfig 's
-functionality, in conjunction with
-.BR ld.so ,
-is only available for executables compiled using libc version 4.4.3 or greater.
-.PP
-.BR ldconfig ,
-being a user process, must be run manually and has no means of dynamically
-determining and relinking shared libraries for use by
-.BR ld.so
-when a new DLL is installed.
