<para><userinput>make mrproper:</userinput> This will ensure that the kernel
|
|
tree is absolutely clean. We do this because the kernel team recommend
|
|
that this is done prior to <emphasis>each</emphasis> kernel compilation,
|
|
and that we shouldn't rely on the source tree being automatically clean
|
|
after untarring.</para>
|
|
|
|
<para><userinput>make include/linux/version.h</userinput> and
|
|
<userinput>make symlinks</userinput>: This creates the
|
|
<filename>include/linux/version.h</filename>, as well as the <filename
|
|
class="symlink">include/asm</filename> symlink.</para>
|
|
|
|
<para><userinput>mkdir $LFS/usr/include/asm</userinput>
|
|
and <userinput>cp include/asm/* $LFS/usr/include/asm</userinput>:
|
|
This copies the platform-specific assembler kernel header files to
|
|
<filename>$LFS/usr/include/asm</filename></para>
|
|
|
|
<para><userinput>cp -R include/linux $LFS/usr/include</userinput>:
|
|
This command copies the cross-platform kernel header files to
|
|
<filename>$LFS/usr/include</filename></para>
|
|
|
|
<para><userinput>touch $LFS/usr/include/linux/autoconf.h</userinput>: Some
|
|
kernel header files include this <filename>autoconf.h</filename> file, but
|
|
outside the Linux source tree, that file has no meaning so we just create
|
|
an empty one so we don't get compile errors whenever it happens to be a
|
|
dependency of another kernel header file.</para>
