176 <para>By default, the dynamic loader (<filename
177 class="libraryfile">/lib/ld-linux.so.2</filename>) searches through
178 <filename class="directory">/lib</filename> and <filename
179 class="directory">/usr/lib</filename> for dynamic libraries that are
180 needed by programs as they are run. However, if there are libraries in
181 directories other than <filename class="directory">/lib</filename> and
182 <filename class="directory">/usr/lib</filename>, these need to be
183 added to the <filename>/etc/ld.so.conf</filename> file in order
184 for the dynamic loader to find them. Two directories that are commonly
185 known to contain additional libraries are
186 <filename class="directory">/usr/local/lib</filename>,
187 <filename class="directory">/usr/local/lib32</filename>,
188 <filename class="directory">/usr/local/lib64</filename>,
189 <filename class="directory">/opt/lib</filename>,
190 <filename class="directory">/opt/lib32</filename>,
191 and <filename class="directory">/opt/lib64</filename>,
192 so add those directories to the dynamic loader's search path.</para>
