LDCONFIG

NAME

SYNOPSIS

/sbin/ldconfig -l [ -v ] library ...

/sbin/ldconfig -p  

DESCRIPTION

ldconfig will attempt to deduce the type of ELF libs (i.e., libc5 or libc6/glibc) based on what C libs, if any, the library was linked against.

Some existing libs do not contain enough information to allow the deduction of their type. Therefore, the /etc/ld.so.conf file format allows the specification of an expected type. This is only used for those ELF libs which we can not work out. The format is "dirname=TYPE", where TYPE can be libc4, libc5, or libc6. (This syntax also works on the command line.) Spaces are not allowed. Also see the -p option. ldconfig should normally be run by the superuser as it may require write permission on some root owned directories and files.  

OPTIONS

-v

Verbose mode. Print current version number, the name of each directory as it is scanned, and any links that are created. Overrides quiet mode.

-n

Only process directories specified on the command line. Don't process the trusted directories (/lib and /usr/lib) nor those specified in /etc/ld.so.conf. Implies -N.

-N

Don't rebuild the cache. Unless -X is also specified, links are still updated.

-X

Don't update links. Unless -N is also specified, the cache is still rebuilt.

-f conf

Use conf instead of /etc/ld.so.conf.

-C cache

Use cache instead of /etc/ld.so.cache.

-r root

Change to and use root as the root directory.

-l

Library mode. Manually link individual libraries. Intended for use by experts only.

-p

Print the lists of directories and candidate libraries stored in the current cache.

FILES

/lib/ld.so

run-time linker/loader

/etc/ld.so.conf

File containing a list of colon, space, tab, newline, or comma-separated directories in which to search for libraries.

/etc/ld.so.cache

File containing an ordered list of libraries found in the directories specified in /etc/ld.so.conf, as well as those found in /lib and /usr/lib.
