106 some failures are unavoidable. This is a list of the most common

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