4<para><userinput>ln -s /static/bin/pwd /bin/pwd</userinput>: The kernel
5source hard-wires the path to <filename>pwd</filename> to be
6<filename>/bin/pwd</filename> so we create a temporary symlink to deal with
7it.</para>
8
9<para><userinput>make mrproper:</userinput> This will ensure that the kernel
10tree is absolutely clean. We do this because the kernel team recommend
11that this is done prior to <emphasis>each</emphasis> kernel compilation,
12and that we shouldn't rely on the source tree being automatically clean
13after untarring.</para>
14
15<para><userinput>make include/linux/version.h</userinput> and
16<userinput>make symlinks</userinput>: This creates the
17<filename>include/linux/version.h</filename>, as well as the <filename
18class="symlink">include/asm</filename> symlink.</para>
19
20<para><userinput>mkdir $LFS/usr/include/asm</userinput>
21and <userinput>cp include/asm/* $LFS/usr/include/asm</userinput>:
22This copies the platform-specific assembler kernel header files to
23<filename>$LFS/usr/include/asm</filename></para>
24
25<para><userinput>cp -R include/linux $LFS/usr/include</userinput>:
26This command copies the cross-platform kernel header files to
27<filename>$LFS/usr/include</filename></para>
28
29<para><userinput>touch $LFS/usr/include/linux/autoconf.h</userinput>: Some
30kernel header files include this <filename>autoconf.h</filename> file, but
31outside the Linux source tree, that file has no meaning so we just create
32an empty one so we don't get compile errors whenever it happens to be a
33dependency of another kernel header file.</para>
