	Linux From Scratch 12.3/chapter02_hostreqs — Chinese (Simplified Han script)	Your host system should have the following software with the minimum versions indicated. This should not be an issue for most modern Linux distributions. Also note that many distributions will place software headers into separate packages, often in the form of <literal><replaceable>&lt;package-name&gt;</replaceable>-devel</literal> or <literal><replaceable>&lt;package-name&gt;</replaceable>-dev</literal>. Be sure to install those if your distribution provides them.	您的宿主系统必须拥有下列软件，且版本不能低于我们给出的最低版本。对于大多数现代 Linux 发行版来说这不成问题。要注意的是，很多发行版会把软件的头文件放在单独的软件包中，这些软件包的名称往往是 <quote>&lt;软件包名&gt;-devel</quote> 或者 <quote>&lt;软件包名&gt;-dev</quote>。如果您的发行版为下列软件提供了这类软件包，一定要安装它们。
	Linux From Scratch 12.3/chapter02_hostreqs — Chinese (Simplified Han script)	The reason for the kernel version requirement is that we specify that version when building <application>glibc</application> in <xref linkend="chapter-cross-tools"/> and <xref linkend="chapter-building-system"/>, so the workarounds for older kernels are not enabled and the compiled <application>glibc</application> is slightly faster and smaller. As at Dec 2024, &min-kernel; is the oldest kernel release still supported by the kernel developers. Some kernel releases older than &min-kernel; may be still supported by third-party teams, but they are not considered official upstream kernel releases; read <ulink url='https://kernel.org/category/releases.html'/> for the details.	内核版本的要求是为了符合第 6 章中编译 <application>glibc</application> 时开发者推荐的配置选项。udev 也要求一定的内核版本。
	Linux From Scratch 12.3/chapter02_hostreqs — Chinese (Simplified Han script)	If the host kernel is earlier than &min-kernel; you will need to replace the kernel with a more up-to-date version. There are two ways you can go about this. First, see if your Linux vendor provides a &min-kernel; or later kernel package. If so, you may wish to install it. If your vendor doesn't offer an acceptable kernel package, or you would prefer not to install it, you can compile a kernel yourself. Instructions for compiling the kernel and configuring the boot loader (assuming the host uses GRUB) are located in <xref linkend="chapter-bootable"/>.	如果宿主内核比 &min-kernel; 更早，您需要将内核升级到较新的版本。升级内核有两种方法，如果您的发行版供应商提供了 &min-kernel; 或更新的内核软件包，您可以直接安装它。如果供应商没有提供一个足够新的内核包，或者您不想安装它，您可以自己编译内核。编译内核和配置启动引导器 (假设宿主使用 GRUB) 的步骤在<xref linkend="chapter-bootable"/>中。
