120 <para>The install will finish by checking that everything is correctly installed.
121 Unfortunately, it will test for a multilib installation. On x86_64 Pure64 this means
122 it will try to test the non-existent 32-bit loader which has a different name
123 from the 64-bit loader (unlike on other 64-bit architectures). We fool it by
124 creating a symlink to the real loader.</para>

136 <para>Now we can remove this symlink. We also need to correct the <command>
137 /usr/bin/ldd</command> script - if you look at this, you will see it references
138 not only the 32-bit linker, but also /lib64 where it thinks the 64-bit linker
139 is. The following <command>sed</command> will correct this:</para>
140
141 <screen><userinput>rm -v /lib/ld-linux.so.2
142cp -v /usr/bin/ldd{,.bak}
143sed '/RTLDLIST/s%/ld-linux.so.2 /lib64%%' /usr/bin/ldd.bak >/usr/bin/ldd</userinput></screen>
144
145 <para>Check the script to make sure the sed worked correctly, then delete
146 the backup.</para>

167 <para>By default, the dynamic loader (<filename
168 class="libraryfile">/lib/ld-linux-x86-64.so.2</filename>) searches through
169 <filename class="directory">/lib</filename> and <filename
170 class="directory">/usr/lib</filename> for dynamic libraries that are
171 needed by programs as they are run. However, if there are libraries in
172 directories other than <filename class="directory">/lib</filename> and
173 <filename class="directory">/usr/lib</filename>, these need to be
174 added to the <filename>/etc/ld.so.conf</filename> file in order
175 for the dynamic loader to find them. Two directories that are commonly
176 known to contain additional libraries are <filename
177 class="directory">/usr/local/lib</filename> and <filename
178 class="directory">/opt/lib</filename>, so add those directories to the
179 dynamic loader's search path.</para>
