6.33.1. 安装 Perl
</h2>
</div>
<p>
对 Perl 的设置进行更多的控制，你可以运行交互的 <strong class="command">Configure</strong> 脚本，精心选择编译配置。如果你能接受 Perl 的自动配置(是很明智的)，就用下面的命令：</p>
<pre class="userinput"><kbd class="command">./configure.gnu --prefix=/usr -Dpager="/bin/less -isR"</kbd></pre>
<p>
配置选项的含义：
</p>
<div class="variablelist">
<dl>
<dt>
<span class="term"><em class="parameter"><tt>-Dpager="/bin/less
-isR"</tt></em></span> </dt>
<dd>
<p>
纠正 <span><strong class="command">perldoc</strong></span> 代码调用 <span><strong class="command">less</strong></span>
程序时的一个错误。</p>
</dd>
</dl>
</div>
<p>编译软件包：</p>
<pre class="userinput"><kbd class="command">make</kbd></pre>
<p>
为了运行测试套件，要先创建一个基本的 <tt class="filename">/etc/hosts</tt> 文件，好几个测试都需要它来解析 localhost 的名称：</p>
<pre class="userinput"><kbd class="command">echo "127.0.0.1 localhost $(hostname)" > /etc/hosts</kbd></pre>
<p>如果你愿意，现在可以运行测试套件了：</p>
<pre class="userinput"><kbd class="command">make test</kbd></pre>
<p>
安装软件包：
</p>
<pre class="userinput"><kbd class="command">make install</kbd></pre>
