  <title>创建 $LFS/tools 目录</title>

  <!--para>All programs compiled in <xref linkend="chapter-temporary-tools"/>
  will be installed under <filename class="directory">$LFS/tools</filename>
  to keep them separate from the programs compiled in <xref
  linkend="chapter-building-system"/>. The programs compiled here are
  temporary tools and will not be a part of the final LFS system. By keeping
  these programs in a separate directory, they can easily be discarded later
  after their use. This also prevents these programs from ending up in the
  host production directories (easy to do by accident in <xref
  linkend="chapter-temporary-tools"/>).</para-->
  <para><xref linkend="chapter-temporary-tools"/>
	  中编译的所有程序都会被安装在
	  <filename class="directory">$LFS/tools</filename>
	  目录中，以便和 <xref linkend="chapter-building-system"/>
	  中编译的程序分离开来。因为前者是临时工具，
	  并不是最终的 LFS 系统的一部分，将它们保存在单独的目录树中，
	  就可以在使用完后容易地删除。
	  另外，这也可以防止它们被意外地安装在宿主环境中 (这种意外在
	  <xref linkend="chapter-temporary-tools"/> 中容易发生)。</para>

  <!--para>Create the required directory by running the following as
  <systemitem class="username">root</systemitem>:</para-->
  <para>以 <systemitem class="username">root</systemitem> 身份执行以下命令，
	  创建这个目录：</para>

<screen><userinput>mkdir -v $LFS/tools</userinput></screen>

  <!--para>The next step is to create a <filename class="symlink">/tools</filename>
  symlink on the host system. This will point to the newly-created directory on
  the LFS partition. Run this command as <systemitem
  class="username">root</systemitem> as well:</para-->
  <para>下一步是在宿主系统中创建一个
	  <filename class="symlink">/tools</filename> 符号链接。
	  这个链接指向刚刚创建的，在 LFS 分区中的目录。以
	  <systemitem class="username">root</systemitem> 身份执行以下命令：
  </para>

<screen><userinput>ln -sv $LFS/tools /</userinput></screen>

  <note>
    <!--para>The above command is correct. The <command>ln</command> command
    has a few syntactic variations, so be sure to check
    <command>info coreutils ln</command> and <filename>ln(1)</filename>
    before reporting what you may think is an error.</para-->
    <para>这个命令是正确的，<command>ln</command>命令的语法有一些变种。
		请先阅读 <command>info coreutils ln</command> 和
		<filename>ln(1)</filename>，而不是直接发邮件断言这是一个错误。
	</para>
  </note>

  <!--para>The created symlink enables the toolchain to be compiled so that it
  always refers to <filename class="directory">/tools</filename>, meaning
  that the compiler, assembler, and linker will work both in Chapter&nbsp;5
  (when we are still using some tools from the host) and in the next (when
  we are <quote>chrooted</quote> to the LFS partition).</para-->
  <para>这个符号链接使得临时工具链总是可以通过
	  <filename class="directory">/tools</filename> 这个路径访问，
	  这样，无论是在第 5 章（我们仍然需要使用宿主的一些工具）和第 6 章
	  （我们已经 <quote>chroot</quote> 到 LFS 分区）中，它们都能正常工作。
