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

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

151 <para os="u">The stubs.h header installed by EGLIBC looks for stubs-32.h
152 and stubs-64.h. This configuration of EGLIBC only generates stubs-64.h. Fix
153 this with the following:</para>

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