147 <para>By default, the dynamic loader (<filename
148 class="libraryfile">/lib/ld-linux.so.2</filename>) searches through
149 <filename class="directory">/lib</filename> and <filename
150 class="directory">/usr/lib</filename> for dynamic libraries that are
151 needed by programs as they are run. However, if there are libraries in
152 directories other than <filename class="directory">/lib</filename>,
153 <filename class="directory">/lib64</filename>,
154 <filename class="directory">/usr/lib</filename>, and
155 <filename class="directory">/usr/lib64</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. Some 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>
