<para>Building the kernel involves a few steps: configuring it and compiling
|
|
it. There are a few ways to configure the kernel. If you don't like the
|
|
way this book does it, read the <filename>README</filename> that comes
|
|
with the kernel source tree, and find out what the other options are.</para>
|
|
|
|
<para>Something you could do, is take the <filename>.config</filename>
|
|
file from your host distribution's kernel source tree and copy it to
|
|
<filename class="directory">$LFS/usr/src/linux</filename>.
|
|
This way you don't have to configure the entire kernel from scratch and
|
|
can use your current values. If you choose to do this, first run the
|
|
<userinput>make mrproper</userinput> command below, then copy the
|
|
<filename>.config</filename> file over, then run
|
|
<userinput>make menuconfig</userinput> followed by the rest of the commands
|
|
(<userinput>make oldconfig</userinput> may be better in some situations.
|
|
See the <filename>README</filename> file for more details when to use
|
|
<userinput>make oldconfig</userinput>).</para>
|
|
|
|
<para>The following commands are run to build the kernel:</para>

|
|
|
<para><screen><userinput>cd /usr/src/linux &&</userinput>
|

<userinput>make mrproper &&</userinput>

different platforms.</para>
