13 <para>Your host system should have the following software with the
14 minimum versions indicated. This should not be an issue for most
15 modern Linux distributions. Also note that many distributions will
16 place software headers into separate packages, often in the form of
17 <quote>&lt;package-name&gt;-devel</quote> or
18 <quote>&lt;package-name&gt;-dev</quote>. Be sure to install those if
19 your distribution provides them.</para>

86
87 <para>The reason for the kernel version requirement is that we specify
88 that version when building <application>glibc</application> in Chapter&nbsp;6
89 at the recommendation of the developers. It is also required by
90 udev.</para>
91
92 <para>If the host kernel is earlier than &min-kernel; you will need to replace
93 the kernel with a more up to date version. There are two ways
94 you can go about this. First, see if your Linux vendor provides a &min-kernel;
95 or later kernel package. If so, you may wish to install it. If your
96 vendor doesn't offer an acceptable kernel package, or you would prefer not to
97 install it, you can compile a kernel yourself. Instructions for
98 compiling the kernel and configuring the boot loader (assuming the host
99 uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>
