155 <para>By default, the dynamic loader (<filename
156 class="libraryfile">/lib/ld-linux.so.2</filename>) searches through
157 <filename class="directory">/lib</filename> and <filename
158 class="directory">/usr/lib</filename> for dynamic libraries that are
159 needed by programs as they are run. However, if there are libraries in
160 directories other than <filename class="directory">/lib</filename> and
161 <filename class="directory">/usr/lib</filename>, these need to be
162 added to the <filename>/etc/ld.so.conf</filename> file in order
163 for the dynamic loader to find them. Some directories that are commonly
164 known to contain additional libraries are
165 <filename class="directory">/usr/local/lib</filename>,
166 <filename class="directory">/usr/local/lib32</filename>,
167 <filename class="directory">/usr/local/lib64</filename>,
168 <filename class="directory">/opt/lib</filename>,
169 <filename class="directory">/opt/lib32</filename>,
170 and <filename class="directory">/opt/lib64</filename>,
171 so add those directories to the dynamic loader's search path.</para>
