ldconfig
LDCONFIG(8) Linux Programmer's Manual LDCONFIG(8)NAME
ldconfig - configure dynamic linker run-time bindings
SYNOPSIS
/sbin/ldconfig [-nNvXV] [-f conf] [-C cache] [-r root] directory...
/sbin/ldconfig -l [-v] library...
/sbin/ldconfig -p
DESCRIPTION
ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line,
in the file /etc/ld.so.conf, and in the trusted directories, /lib and /usr/lib (on some 64-bit architectures such as x86-64, lib and
/usr/lib are the trusted directories for 32-bit libraries, while /lib64 and /usr/lib64 are used for 64-bit libraries).
The cache is used by the run-time linker, ld.so or ld-linux.so. ldconfig checks the header and filenames of the libraries it encounters
when determining which versions should have their links updated.
ldconfig will attempt to deduce the type of ELF libraries (i.e., libc5 or libc6/glibc) based on what C libraries, if any, the library was
linked against.
Some existing libraries 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 used only for those ELF libraries 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 -c fmt, --format=fmt
(Since glibc 2.2) Cache format to use: old, new, or compat (default).
-C cache
Use cache instead of /etc/ld.so.cache.
-f conf
Use conf instead of /etc/ld.so.conf.
-i, --ignore-aux-cache
(Since glibc 2.7) Ignore auxiliary cache file.
-l (Since glibc 2.2) Library mode. Manually link individual libraries. Intended for use by experts only.
-n Process only the directories specified on the command line. Don't process the trusted directories, 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.
-p, --print-cache
Print the lists of directories and candidate libraries stored in the current cache.
-r root
Change to and use root as the root directory.
-v, --verbose
Verbose mode. Print current version number, the name of each directory as it is scanned, and any links that are created. Overrides
quiet mode.
-V, --version
Print program version.
-X Don't update links. Unless -N is also specified, the cache is still rebuilt.
FILES
/lib/ld.so
Run-time linker/loader.
/etc/ld.so.conf
File containing a list of directories, one per line, 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 the
trusted directories.
