Next comes glibc. The most important considerations for building glibc are the compiler, binary tools, and kernel headers. The compiler and binary tools are generally not an issue since glibc will always those relating to the <parameter>--host</parameter> parameter passed to its configure script; e.g., in our case, the compiler will be <command>$LFS_TGT-gcc</command> and the <command>readelf</command> tool will be <command>$LFS_TGT-readelf</command>. The kernel headers can be a bit more complicated. Therefore, we take no risks and use the available configure switch to enforce the correct selection. After the run of <command>configure</command>, check the contents of the <filename>config.make</filename> file in the <filename class="directory">build</filename> directory for all important details. These items highlight an important aspect of the glibc package&mdash;it is very self-sufficient in terms of its build machinery, and generally does not rely on toolchain defaults.
下一步安装 Glibc。在构建 Glibc 时需要着重考虑编译器，二进制工具，以及内核头文件。编译器一般不成问题，Glibc 总是使用传递给配置脚本的 <parameter>--host</parameter> 参数相关的编译器。例如，在我们的例子中，使用的编译器是 <command>$LFS_TGT-gcc</command>。但二进制工具和内核头文件的问题比较复杂。安全起见，我们使用配置脚本提供的开关，保证正确的选择。在 <command>configure</command> 脚本运行完成后，可以检查 <filename>build</filename> 目录中的 <filename>config.make</filename> 文件，了解全部重要的细节。注意参数 <parameter>CC="$LFS_TGT-gcc"</parameter> (其中 <envar>$LFS_TGT</envar> 会被展开) 控制构建系统使用正确的二进制工具，而参数 <parameter>-nostdinc</parameter> 和 <parameter>-isystem</parameter> 控制编译器的包含文件搜索路径。这些事项凸显了 Glibc 软件包的一个重要性质 —— 它的构建机制是相当自给自足的，通常不依赖于工具链默认值。

Note the use of <parameter>CC="$LFS_TGT-gcc"</parameter> (with <envar>$LFS_TGT</envar> expanded) to control which binary tools are used and the use of the <parameter>-nostdinc</parameter> and <parameter>-isystem</parameter> flags to control the compiler's include search path. These items highlight an important aspect of the Gglibc package&mdash;it is very self-sufficient in terms of its build machinery, and generally does not rely on toolchain defaults.

You should also be aware of the name of the platform's dynamic linker, often referred to as the dynamic loader (not to be confused with the standard linker <command>ld</command> that is part of binutils). The dynamic linker provided by package glibc finds and loads the shared libraries needed by a program, prepares the program to run, and then runs it. The name of the dynamic linker for a 32-bit Intel machine is <filename class="libraryfile">ld-linux.so.2</filename>; it's <filename class="libraryfile">ld-linux-x86-64.so.2</filename> on 64-bit systems. A sure-fire way to determine the name of the dynamic linker is to inspect a random binary from the host system by running: <userinput>readelf -l &lt;name of binary&gt; | grep interpreter</userinput> and noting the output. The authoritative reference covering all platforms is in <ulink url='https://sourceware.org/glibc/wiki/ABIList'>a Glibc wiki page</ulink>.
另外注意平台的动态链接器的名称，它又被称为动态加载器 (不要和 Binutils 中的普通链接器 <command>ld</command> 混淆)。动态链接器由 Glibc 提供，它寻找并加载程序所需的共享库，为程序运行做好准备，然后运行程序。在 32 位 Intel 机器上动态链接器的名称是 <filename class="libraryfile">ld-linux.so.2</filename> (在 64 位系统上是 <filename class="libraryfile">ld-linux-x86-64.so.2</filename>)。一个确定动态链接器名称的准确方法是从宿主系统找一个二进制可执行文件，然后执行：<userinput>readelf -l &lt;二进制文件名&gt; | grep interpreter</userinput> 并观察输出。包含所有平台的权威参考可以在 Glibc 源码树根目录的 <filename>shlib-versions</filename> 文件中找到。
