ldconfig

Configure symlinks and cache for shared library dependencies.

• Update symlinks and rebuild the cache (usually run when a new library is installed):

sudo ldconfig

• Update the symlinks for a given directory:

sudo ldconfig -n {{path/to/directory}}

• Print the libraries in the cache and check whether a given library is present:

ldconfig -p | grep {{library_name}}
