Upon entering the chroot environment in <xref linkend="chapter-chroot-temporary-tools"/>, the temporary installations of programs needed for the proper operation of the toolchain are performed. From this point onwards, the core toolchain is self-contained and self-hosted. In <xref linkend="chapter-building-system"/>, final versions of all the packages needed for a fully functional system are built, tested, and installed.
在<xref linkend="chapter-chroot-temporary-tools"/>中，进入 chroot 环境后，首先安装 libstdc++。之后临时性地安装工具链的正常工作所必须的程序。还要构建测试其他程序时必须的程序。此后，核心工具链成为自包含的本地工具链。在<xref linkend="chapter-building-system"/>中，构建、测试并最后一次安装所有软件包，它们组成功能完整的系统。

At the end of <xref linkend="chapter-temporary-tools"/> the native LFS compiler is installed. First binutils-pass2 is built, in the same <envar>DESTDIR</envar> directory as the other programs, then the second pass of gcc is constructed, omitting some non-critical libraries. Due to some weird logic in gcc's configure script, <envar>CC_FOR_TARGET</envar> ends up as <command>cc</command> when the host is the same as the target, but different from the build system. This is why <parameter>CC_FOR_TARGET=$LFS_TGT-gcc</parameter> is declared explicitly as one of the configuration options.
在<xref linkend="chapter-temporary-tools"/>一节的末尾，构建 lfs 本地编译器。首先使用和其他程序相同的 <envar>DESTDIR</envar> 第二次构建 binutils，然后第二次构建 GCC，构建时忽略 libstdc++ 和其他不重要的库。由于 GCC 配置脚本的一些奇怪逻辑，<envar>CC_FOR_TARGET</envar> 变量在 host 系统和 target 相同，但与 build 不同时，被设定为 <command>cc</command>。因此我们必须显式地在配置选项中指定 <parameter>CC_FOR_TARGET=$LFS_TGT-gcc</parameter>。

As mentioned above, the standard C++ library is compiled next, followed in <xref linkend="chapter-temporary-tools"/> by other programs that must be cross-compiled to break circular dependencies at build time. The install step of all those packages uses the <envar>DESTDIR</envar> variable to force installation in the LFS filesystem.
正如前文所述，接下来构建 C++ 标准库，然后是<xref linkend="chapter-temporary-tools"/>中那些需要自身才能构建的程序后。在安装这些软件包时使用 <envar>DESTDIR</envar> 变量，将它安装到 LFS 文件系统中。

Next comes glibc. The most important considerations for building glibc are the compiler, binary tools, and kernel headers. The compiler is generally not an issue since glibc will always use the compiler relating to the <parameter>--host</parameter> parameter passed to its configure script; e.g., in our case, the compiler will be <command>$LFS_TGT-gcc</command>. The binary tools and kernel headers can be a bit more complicated. Therefore, we take no risks and use the available configure switches to enforce the correct selections. After the run of <command>configure</command>, check the contents of the <filename>config.make</filename> file in the <filename class="directory">build</filename> directory for all important details. Note the use of <parameter>CC="$LFS_TGT-gcc"</parameter> (with <envar>$LFS_TGT</envar> expanded) to control which binary tools are used and the use of the <parameter>-nostdinc</parameter> and <parameter>-isystem</parameter> flags to control the compiler's include search path. These items highlight an important aspect of the glibc package&mdash;it is very self-sufficient in terms of its build machinery, and generally does not rely on toolchain defaults.
下一步安装 Glibc。在构建 Glibc 时需要着重考虑编译器，二进制工具，以及内核头文件。编译器一般不成问题，Glibc 总是使用传递给配置脚本的 <parameter>--host</parameter> 参数相关的编译器。例如，在我们的例子中，使用的编译器是 <command>$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。

Next up: sanitized Linux API headers. These allow the standard C library (glibc) to interface with features that the Linux kernel will provide.
下一步安装“净化的” (sanitized) Linux API 头文件。这允许 C 标准库 (Glibc) 与 Linux 内核提供的各种特性交互。

Detailed information can be obtained from <command>gcc</command> by passing it the <parameter>-v</parameter> command line option while compiling a program. For example, <command>$LFS_TGT-gcc -v <replaceable>example.c</replaceable></command> (or without <command> $LFS_TGT-</command> if coming back later) will show detailed information about the preprocessor, compilation, and assembly stages, including <command>gcc</command>'s search paths for included headers and their order.
通过向 <command>gcc</command> 传递 <parameter>-v</parameter> 参数，可以知道在编译样品程序时发生的细节。例如，<command>gcc -v dummy.c</command> 会输出预处理、编译和汇编阶段中的详细信息，包括 <command>gcc</command> 的包含文件搜索路径和顺序。
