163 <para>By default, the dynamic loader (<filename

166 <filename class="directory">/lib64</filename>,
167 <filename class="directory">/usr/lib</filename>,
168 and <filename class="directory">/usr/lib64</filename> for dynamic
169 libraries that are needed by programs as they are run. However, if
170 there are libraries in directories other than these, they need to be
171 added to the <filename>/etc/ld.so.conf</filename> file in order
172 for the dynamic loader to find them. Some directories that are commonly
173 known to contain additional libraries are
174 <filename class="directory">/usr/local/lib</filename>,

176 <filename class="directory">/opt/lib</filename>,
