How do I install new dynamically linked shared libraries?
These instructions apply regardless of how you build a dynamically linked shared library: • If your library will be used by programs that run in single user mode (when /usr is not yet mounted), you should install your library in the /shlib directory. If it’s an X library, then put it in /usr/X11R6/lib. Otherwise, the standard locations are /usr/contrib/lib or /usr/lib. All of these directories are in the standard shared library path in /etc/ld.so.conf. If you use the standard make headers, the LIBDIR variable and the /etc/shlib.map file control the location of the dynamically linked shared library (see above). • After you install a new shared library (that is, if you did not merely overwrite an existing shared library), you must run the ldconfig program as the superuser in order to rebuild the /etc/ld.so.cache database that the dynamic linker queries when it searches for shared libraries.
