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 header files in <filename>include/linux</filename>, likeversion.h, among others, that we will need to compile Glibc and otherpackages later in chroot.</para><para><userinput>make dep:</userinput> make dep checks dependencies and setsup the dependencies file. We don't really care about the dependencychecks, but what we do care about is that make dep creates thoseaforementioned files in <filename>include/linux</filename> we will beneeding later on.</para><para><userinput>cp -HR include/asm $LFS/usr/include</userinput>and <userinput>cp -HR include/linux $LFS/usr/include</userinput>:These commands copy the required kernel header files to<filename>$LFS/usr/include</filename>.</para></sect2>
