This is done by way of sanitizing various C header files that are shipped in the Linux kernel source tarball. Make sure there are no stale files and dependencies lying around from previous activity: make mrproper Now extract the user-visible kernel headers from the source. The recommended make target headers_install cannot be used, because it requires rsync, which is not available in /tools. The headers are first placed in ./usr, then some files used by the kernel developers are removed, then the files are copied to their final location. make headers find usr/include -name '.*' -delete rm usr/include/Makefile cp -rv usr/include/* /usr/include Contents of Linux API Headers Installed headers Installed directories /usr/include/asm/*.h, /usr/include/asm-generic/*.h, /usr/include/drm/*.h, /usr/include/linux/*.h, /usr/include/misc/*.h, /usr/include/mtd/*.h, /usr/include/rdma/*.h, /usr/include/scsi/*.h, /usr/include/sound/*.h, /usr/include/video/*.h, and /usr/include/xen/*.h /usr/include/asm, /usr/include/asm-generic, /usr/include/drm, /usr/include/linux, /usr/include/misc, /usr/include/mtd, /usr/include/rdma, /usr/include/scsi, /usr/include/sound, /usr/include/video, and /usr/include/xen Short Descriptions /usr/include/asm/*.h The Linux API ASM Headers /usr/include/asm/*.h /usr/include/asm-generic/*.h The Linux API ASM Generic Headers /usr/include/asm-generic/*.h /usr/include/drm/*.h The Linux API DRM Headers /usr/include/drm/*.h /usr/include/linux/*.h The Linux API Linux Headers /usr/include/linux/*.h /usr/include/misc/*.h The Linux API Miscellaneous Headers /usr/include/misc/*.h /usr/include/mtd/*.h The Linux API MTD Headers /usr/include/mtd/*.h /usr/include/rdma/*.h The Linux API RDMA Headers /usr/include/rdma/*.h /usr/include/scsi/*.h The Linux API SCSI Headers /usr/include/scsi/*.h /usr/include/sound/*.h The Linux API Sound Headers /usr/include/sound/*.h /usr/include/video/*.h The Linux API Video Headers /usr/include/video/*.h /usr/include/xen/*.h The Linux API Xen Headers /usr/include/xen/*.h
