172 <para>By default, the dynamic loader (<filename
173 class="libraryfile">/lib/ld-linux.so.2</filename>) searches through
174 <filename class="directory">/lib</filename> and <filename
175 class="directory">/usr/lib</filename> for dynamic libraries that are
176 needed by programs as they are run. However, if there are libraries in
177 directories other than <filename class="directory">/lib</filename> and
178 <filename class="directory">/usr/lib</filename>, these need to be
179 added to the <filename>/etc/ld.so.conf</filename> file in order
180 for the dynamic loader to find them. Two directories that are commonly
181 known to contain additional libraries are
182 <filename class="directory">/usr/local/lib</filename>,
183 <filename class="directory">/usr/local/lib64</filename>,
184 <filename class="directory">/opt/lib</filename>,
185 and <filename class="directory">/opt/lib64</filename>,
186 so add those directories to the dynamic loader's search path.</para>
