GCC requires the GMP, MPFR and MPC packages. As these packages may not be included in your host distribution, they will be built with GCC. Unpack each package into the GCC source directory and rename the resulting directories so the GCC build procedures will automatically use them:

There are frequent misunderstandings about this chapter. The procedures are the same as every other chapter, as explained earlier (<xref linkend='buildinstr'/>). First, extract the gcc-&gcc-version; tarball from the sources directory, and then change to the directory created. Only then should you proceed with the instructions below.

This option specifies the version of Glibc which will be used on the target. It is not relevant to the libc of the host distro because everything compiled by pass1 GCC will run in the chroot environment, which is isolated from libc of the host distro.

Since a working C library is not yet available, this ensures that the inhibit_libc constant is defined when building libgcc. This prevents the compiling of any code that requires libc support.

When creating a complete cross-compiler, GCC requires standard headers compatible with the target system. For our purposes these headers will not be needed. This switch prevents GCC from looking for them.

Those switches allow GCC to compile programs with some hardening security features (more information on those in the <xref linkend="pie-ssp-info"/> in chapter 8) by default. They are not strictly needed at this stage, since the compiler will only produce temporary executables. But it is cleaner to have the temporary packages be as close as possible to the final ones.

This switch forces GCC to link its internal libraries statically. We need this because the shared libraries require Glibc, which is not yet installed on the target system.
这个开关强制 GCC 静态链接它的内部库。我们必须这样做，因为动态库需要目标系统中尚未安装的 glibc。

These switches disable support for threading, libatomic, libgomp, libquadmath, libssp, libvtv, and the C++ standard library respectively. These features may fail to compile when building a cross-compiler and are not necessary for the task of cross-compiling the temporary libc.

Compile GCC by running:
 
Linux From Scratch 12.2/chapter05_gcc-pass1 — Chinese (Simplified Han script)
This build of GCC has installed a couple of internal system headers. Normally one of them, <filename>limits.h</filename>, would in turn include the corresponding system <filename>limits.h</filename> header, in this case, <filename>$LFS/usr/include/limits.h</filename>. However, at the time of this build of GCC <filename>$LFS/usr/include/limits.h</filename> does not exist, so the internal header that has just been installed is a partial, self-contained file and does not include the extended features of the system header. This is adequate for building Glibc, but the full internal header will be needed later. Create a full version of the internal header using a command that is identical to what the GCC build system does in normal circumstances:
刚刚构建的 GCC 安装了若干内部系统头文件。其中的 <filename>limits.h</filename> 一般来说，应该包含对应的系统头文件 <filename>limits.h</filename>，在我们的 LFS 环境中，就是 <filename>$LFS/usr/include/limits.h</filename>。然而，在构建 GCC 的时候，<filename>$LFS/usr/include/limits.h</filename> 还不存在，因此 GCC 安装的内部头文件是一个不完整的、自给自足的文件，不包含系统头文件提供的扩展特性。这对于构建临时的 libc 已经足够了，但后续工作将需要完整的内部头文件。使用以下命令创建一个完整版本的内部头文件，该命令与 GCC 构建系统在一般情况下生成该头文件的命令是一致的：

The command below shows an example of nested command substitution using two methods: backquotes and a <literal>$()</literal> construct. It could be rewritten using the same method for both substitutions, but is shown this way to demonstrate how they can be mixed. Generally the <literal>$()</literal> method is preferred.
