149 <para>By default, the dynamic loader (<filename
150 class="libraryfile">/lib/ld-linux.so.2</filename>) searches through
151 <filename class="directory">/lib</filename> and <filename
152 class="directory">/usr/lib</filename> for dynamic libraries that are
153 needed by programs as they are run. However, if there are libraries in
154 directories other than <filename class="directory">/lib</filename> and
155 <filename class="directory">/usr/lib</filename>, these need to be
156 added to the <filename>/etc/ld.so.conf</filename> file in order
157 for the dynamic loader to find them. Two directories that are commonly
158 known to contain additional libraries are
159 <filename class="directory">/usr/local/lib</filename>,
160 <filename class="directory">/usr/local/lib64</filename>,
161 <filename class="directory">/opt/lib</filename>,
162 and <filename class="directory">/opt/lib64</filename>,
163 so add those directories to the dynamic loader's search path.</para>
