Ldconfig
From HwdMediaShare Documentation
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). The cache is used by the run-time linker, ld.so or ld-linux.so.ldconfig checks the header and file names of the libraries it encounters when determining which versions should have their links updated.
