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

177 <filename class="directory">/lib64</filename>,
178 <filename class="directory">/usr/lib</filename>,
179 and <filename class="directory">/usr/lib64</filename> for dynamic
180 libraries that are needed by programs as they are run. However, if
181 there are libraries in directories other than these, they need to be
182 added to the <filename>/etc/ld.so.conf</filename> file in order
183 for the dynamic loader to find them. Some directories that are commonly
184 known to contain additional libraries are
185 <filename class="directory">/usr/local/lib</filename>,

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