155 <para>By default, the dynamic loader (<filename
156 class="libraryfile">/lib/ld-linux.so.2</filename>) searches through
[54d004a8]157 <filename class="directory">/lib</filename>,
[6bb43b3]158 <filename class="directory">/lib64</filename>,
[54d004a8]159 <filename class="directory">/usr/lib</filename>,
160 and <filename class="directory">/usr/lib64</filename> for dynamic
161 libraries that are needed by programs as they are run. However, if
162 there are libraries in directories other than these, they need to be
[3f8be484]163 added to the <filename>/etc/ld.so.conf</filename> file in order
[014d098b]164 for the dynamic loader to find them. Some directories that are commonly
[3f8be484]165 known to contain additional libraries are
166 <filename class="directory">/usr/local/lib</filename>,
167 <filename class="directory">/usr/local/lib64</filename>,
168 <filename class="directory">/opt/lib</filename>,
169 and <filename class="directory">/opt/lib64</filename>,
