4.5.2. Contents of Linux-Headers
Installed headers:
${CLFS}/cross-tools/${CLFS_TARGET}/include/{asm,asm-generic,drm,linux,mtd,rdma,scsi,sound,video,xen}/*.h
The Linux Kernel contains a make target that installs “sanitized” kernel headers.
For this step you will need the kernel tarball.
Install the header files that are common to all architectures:
make mrproper
make ARCH=${CLFS_ARCH} headers
find usr/include -type f ! -name '*.h' -delete
cp -rv usr/include ${CLFS}/cross-tools/${CLFS_TARGET}
