本小节里的步骤是可选的，但如果你的LFS分区容量比较小，知道有些不必要的内容可以被删除也是挺好的。目前编译好的可执行文件和库大概会有70MB左右不需要的调试符号。可以通过下面的命令移除这些符号：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">strip --strip-debug /tools/lib/*
|
||
/usr/bin/strip --strip-unneeded /tools/{,s}bin/*</kbd>
|
||
</pre>
|
||
<p>
|
||
这两个命令会跳过一些文件，并提示不可识别的文件格式。大多数是脚本文件而不是二进制文件。同样还可以用宿主系统里的strip命令为/tools目录下的strip二进制文件瘦身。
|
||
</p>
|
||
<p>
|
||
注意<span class="emphasis"><em>不要</em></span>对库文件使用<em class="parameter"><code>--strip-unneeded</code></em>选项。静态库会被损坏导致整个工具链将会需要全部重新编译。
|
||
</p>
|
||
<p>
|
||
更节省更多空间，还可以删除帮助文档：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">rm -rf /tools/{,share}/{info,man,doc}</kbd>
|
||
</pre>
|
||
<p>
|
||
这个时候，你应该在<code class="envar">$LFS</code>分区中为下个阶段编译安装Glibc和Gcc预留至少3GB剩余空间。如果你可以编译安装Glibc，那其他的就不会有问题了。
