Installation of Perl </h2> </div> <p> In multilib builds we install compilers and libraries for each available architecture. The description below says that perl installs several hundred libraries, but they are used by invoking <span><strong class="command">perl</strong></span>, not by linking to them with <span><strong class="command">ld</strong></span>. Although it is possible to install perl for 32 bits, move it to a different name, and then install the 64-bit version, it is almost always invoked as just <span><strong class= "command">perl</strong></span>. That means only the libraries and modules for the last version installed will be accessible. We therefore only install one version. </p> <p> Perl does not, by default, know about library directories with names other than lib, such as lib64. The following patch will allow it to install to lib64. </p> <pre class="userinput"><kbd class="command">patch -Np1 -i ../perl-5.8.8-Configure_multilib-1.patch</kbd></pre> <p> There is a further (possibly cosmetic) anomaly - if we install perl and then run <span><strong class="command">perl -V</strong></span> it will claim that libc is in /lib.
