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

128 <para>Now we can remove this symlink. We also need to correct the <command>
129 /usr/bin/ldd</command> script - if you look at this, you will see it references
130 not only the 32-bit linker, but also /lib64 where it thinks the 64-bit linker
131 is. The following <command>sed</command> will correct this:</para>

134cp -v /usr/bin/ldd{,.bak}
135sed '/RTLDLIST/s%/ld-linux.so.2 /lib64%%' /usr/bin/ldd.bak >/usr/bin/ldd</userinput></screen>
136
137 <para>Check the script to make sure the sed worked correctly, then delete
138 the backup.</para>

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