	<userinput remap="configure">../configure --prefix=/usr \ --disable-werror \ --enable-kernel=&min-kernel; \ --enable-stack-protector=strong \ --disable-nscd \ libc_cv_slibdir=/usr/lib</userinput>	<userinput remap="configure">../configure --prefix=/usr \ --disable-werror \ --enable-kernel=&min-kernel; \ --enable-stack-protector=strong \ --with-headers=/usr/include \ libc_cv_slibdir=/lib</userinput>
	The meaning of the configure options:	配置选项的含义：
	<parameter>--disable-werror</parameter>	<parameter>--disable-werror</parameter>
	This option disables the -Werror option passed to GCC. This is necessary for running the test suite.	该选项禁用 GCC 的 -Werror 选项。这对于运行测试套件来说是必须的。
	<parameter>--enable-kernel=&min-kernel;</parameter>	<parameter>--enable-kernel=&min-kernel;</parameter>
	This option tells the build system that this Glibc may be used with kernels as old as &min-kernel;. This means generating workarounds in case a system call introduced in a later version cannot be used.	该选项告诉构建系统 Glibc 可能被与 &min-kernel; 这样老版本的内核一起使用。这样，Glibc 会生成代码，在后续版本引入的系统调用不可用时绕过它们。
	<parameter>--enable-stack-protector=strong</parameter>	<parameter>--enable-stack-protector=strong</parameter>
	This option increases system security by adding extra code to check for buffer overflows, such as stack smashing attacks. Note that Glibc always explicitly overrides the default of GCC, so this option is still needed even though we've already specified <option>--enable-default-ssp</option> for GCC.
	<parameter>--disable-nscd</parameter>	<parameter>--disable-werror</parameter>
	Do not build the name service cache daemon which is no longer used.
	<parameter>libc_cv_slibdir=/usr/lib</parameter>	<parameter>libc_cv_slibdir=/lib</parameter>
	This variable sets the correct library for all systems. We do not want lib64 to be used.	这个变量纠正库文件安装位置。我们不希望使用 lib64 目录。
	Compile the package:	编译该软件包：
	<userinput remap="make">make</userinput>	<userinput remap="make">make</userinput>
	In this section, the test suite for Glibc is considered critical. Do not skip it under any circumstance.	我们认为，在本节中，Glibc 的测试套件十分关键。在任何情况下都不要跳过它。
	Generally a few tests do not pass. The test failures listed below are usually safe to ignore.	通常来说，可能会有极少数测试不能通过，下面列出的失败结果一般可以安全地忽略。执行以下命令进行测试：
	<userinput remap="test">make check</userinput>	<userinput remap="test">make check</userinput>
	You may see some test failures. The Glibc test suite is somewhat dependent on the host system. A few failures out of over 5000 tests can generally be ignored. This is a list of the most common issues seen for recent versions of LFS:	您可能看到一些失败结果。Glibc 的测试套件和宿主系统之间有某种依赖关系。下面列出是在一些版本的 LFS 上发现的，最常见的问题：
	<emphasis>io/tst-lchmod</emphasis> is known to fail in the LFS chroot environment.	已知 <emphasis>io/tst-lchmod</emphasis> 在 LFS chroot 环境中会失败。
	Some tests, for example <emphasis>nss/tst-nss-files-hosts-multi</emphasis> and <emphasis>nptl/tst-thread-affinity*</emphasis> are known to fail due to a timeout (especially when the system is relatively slow and/or running the test suite with multiple parallel make jobs). These tests can be identified with:
	<userinput remap="test">grep "Timed out" $(find -name \*.out)</userinput>	<userinput remap="make">make</userinput>
	It's possible to re-run a single test with enlarged timeout with <command>TIMEOUTFACTOR=<replaceable><factor></replaceable> make test t=<replaceable><test name></replaceable></command>. For example, <command>TIMEOUTFACTOR=10 make test t=nss/tst-nss-files-hosts-multi</command> will re-run <emphasis>nss/tst-nss-files-hosts-multi</emphasis> with ten times the original timeout.
	Additionally, some tests may fail with a relatively old CPU model (for example <emphasis>elf/tst-cpu-features-cpuinfo</emphasis>) or host kernel version (for example <emphasis>stdlib/tst-arc4random-thread</emphasis>).
	Though it is a harmless message, the install stage of Glibc will complain about the absence of <filename>/etc/ld.so.conf</filename>. Prevent this warning with:	在安装 Glibc 时，它会抱怨文件 <filename>/etc/ld.so.conf</filename> 不存在。尽管这是一条无害的消息，执行以下命令即可防止这个警告：
	<userinput remap="install">touch /etc/ld.so.conf</userinput>	<userinput remap="install">touch /etc/ld.so.conf</userinput>
	Fix the Makefile to skip an outdated sanity check that fails with a modern Glibc configuration:	修正生成的 Makefile，跳过一个在 LFS 的不完整环境中会失败的完整性检查：
	<userinput remap="install">sed '/test-installation/s@$(PERL)@echo not running@' -i ../Makefile</userinput>	<userinput remap="install">sed '/test-installation/s@$(PERL)@echo not running@' -i ../Makefile</userinput>
	If upgrading Glibc to a new minor version (for example, from Glibc-2.36 to Glibc-&glibc-version;) on a running LFS system, you need to take some extra precautions to avoid breaking the system:
	Upgrading Glibc on a LFS system prior to 11.0 (exclusive) is not supported. Rebuild LFS if you are running such an old LFS system but you need a newer Glibc.
	If upgrading on a LFS system prior to 12.0 (exclusive), install <application>Libxcrypt</application> following <xref role='.' linkend='ch-system-libxcrypt'/> In addition to a normal <application>Libxcrypt</application> installation, <emphasis role='bold'>you MUST follow the note in Libxcrypt section to install <filename class='libraryfile'>libcrypt.so.1*</filename> (replacing <filename class='libraryfile'>libcrypt.so.1</filename> from the prior Glibc installation)</emphasis>.
	If upgrading on a LFS system prior to 12.1 (exclusive), remove the <command>nscd</command> program:
