6.53.1. 安装 Psmisc
</h2>
</div>
<p>为编译 Psmisc 做准备：</p>
<pre class="userinput"><kbd class="command">./configure --prefix=/usr --exec-prefix=""</kbd></pre>
<p>
配置选项的含义：
</p>
<div class="variablelist">
<dl>
<dt>
<span class="term"><em class="parameter"><tt>--exec-prefix=""</tt></em></span> </dt>
<dd>
<p>
这个确保 Psmisc 二进制文件按照 FHS 标准被安装在
<tt class="filename">/bin</tt> 而不是 <tt class="filename">/usr/bin</tt> ，因为一些 Psmisc 二进制文件将被 LFS-Bootscripts 使用。</p>
</dd>
</dl>
</div>
<p>编译软件包：</p>
<pre class="userinput"><kbd class="command">make</kbd></pre>
<p>
安装软件包：
</p>
<pre class="userinput"><kbd class="command">make install</kbd></pre>
<p>
没有理由把 <span><strong class="command">pstree</strong></span> 和 <span><strong class="command">pstree.x11</strong></span> 程序安装在
<tt class="filename">/bin</tt> 中，所以将他们移动到 <tt class="filename">/usr/bin</tt> 中：</p>
<pre class="userinput"><kbd class="command">mv /bin/pstree* /usr/bin</kbd></pre>
<p>
默认情况下， Psmisc 的 <span><strong class="command">pidof</strong></span> 程序未被安装。 这通常情况下不是问题。因为它将在这之后的 Sysvinit 包中被安装，而且这个包提供了一个更好的 <span><strong class="command">pidof</strong></span> 程序。 如果 Sysvinit 在某个特别的系统中不被使用，则可以通过创建以下的印象链接来完整安装 Psmisc：</p>
<pre class="userinput"><kbd class="command">ln -s killall /bin/pidof</kbd></pre>
