<userinput>yes "" | make config:</userinput> This runs make config and
|
|
answers with the default answer to every question the config script asks
|
|
the user (it does this by simply doing the equivalent of hitting the
|
|
Enter key, thus accepting the default Y and N answers to the questions).
|
|
We're not configuring the real kernel here, we just need to have some sort
|
|
of configure file created so that we can run make dep next that will
|
|
create a few files in $LFS/usr/src/linux/include/linux, like version.h,
|
|
among others, that we will need to compile Glibc and other packages later
|
|
in chroot.

<para>
|
|
<userinput>make dep:</userinput> make dep checks dependencies and sets
|
|
up the dependencies file. We don't really care about the dependency
|
|
checks, but what we do care about is that make dep creates those
|
|
aforementioned files in $LFS/usr/src/linux/include/linux we will be
|
|
needing later on.

<para>
|
|
<userinput>ln -s ../src/linux/include/linux</userinput> and
|
|
<userinput>ln -s ../src/linux/include/asm:</userinput> These
|
|
commands create the linux and asm symlinks in the $LFS/usr/include
|
|
directory that point to the proper directories in the Linux source tree.
|
|
Packages that need kernel headers include them with lines like #include
|
|
<linux/errno.h>. These paths are relative to the /usr/include
|
|
directory so the /usr/include/linux link points to the directory
|
|
containing the Linux kernel header files. The same goes for the asm
|
|
symlink.
