To put 11# this simply, you DO NOT. 12# 13# Why? These headers are used to build the libc. If you customise the 14# headers you are customising the libc and the libc becomes machine 15# specific. Most people do not add custom libc extensions to the kernel 16# and have a machine specific libc. 17# 18# But you have some kernel headers you need for some driver? That is fine 19# but get them from STAGING_KERNEL_DIR where the kernel installs itself. 20# This will make the package using them machine specific but this is much 21# better than having a machine specific C library. This does mean your 22# recipe needs a 23# do_configure[depends] += "virtual/kernel:do_shared_workdir" 24# but again, that is fine and makes total sense. 25# 26# There can also be a case where your kernel extremely old and you want 27# an older libc ABI for that old kernel. The headers installed by this 28# recipe should still be a standard mainline kernel, not your own custom 29# one. 30# 31# -- RP 32 33LIC_FILES_CHKSUM = "file://COPYING;md5=d7810fab7487fb0aad327b76f1be7cd7" 34 35python __anonymous () { 36 major = d.getVar("PV").split('.')[0] 37 if major == "3": 38 d.setVar("HEADER_FETCH_VER", "3.0") 39 elif major == "4": 40 d.setVar("HEADER_FETCH_VER", "4.x") 41 else: 42 d.setVar("HEADER_FETCH_VER", "2.6") 43} 44 45inherit kernel-arch pkgconfig multilib_header 46 47KORG_ARCHIVE_COMPRESSION ?= "xz" 48 49SRC_URI = "${KERNELORG_MIRROR}/linux/kernel/v${HEADER_FETCH_VER}/linux-${PV}.tar.${KORG_ARCHIVE_COMPRESSION}" 50UPSTREAM_CHECK_URI = "https://www.kernel.org/" 51 52S = "${WORKDIR}/linux-${PV}" 53 54EXTRA_OEMAKE = " HOSTCC="${BUILD_CC}" HOSTCPP="${BUILD_CPP}"" 55 56do_configure() { 57 oe_runmake allnoconfig 58} 59 60do_compile () { 61} 62 63do_install() { 64 oe_runmake headers_install INSTALL_HDR_PATH=${D}${exec_prefix} 65 # Kernel should not be exporting this header 66 rm -f ${D}${exec_prefix}/include/scsi/scsi.h 67 68 # The ..install.cmd conflicts between various configure runs 69 find ${D}${includedir} -name ..install.cmd | xargs rm -f 70} 71 72do_install_append_aarch64 () { 73 do_install_armmultilib 74} 75 76do_install_append_arm () { 77 do_install_armmultilib 78} 79 80do_install_armmultilib () { 81 oe_multilib_header asm/auxvec.h asm/bitsperlong.h asm/byteorder.h asm/fcntl.h asm/hwcap.h asm/ioctls.h asm/kvm.h asm/kvm_para.h asm/mman.h asm/param.h asm/perf_regs.h asm/bpf_perf_event.h 82 oe_multilib_header asm/posix_types.h asm/ptrace.h asm/setup.h asm/sigcontext.h asm/siginfo.h asm/signal.h asm/stat.h asm/statfs.h asm/swab.h asm/types.h asm/unistd.h 83} 84 85BBCLASSEXTEND = "nativesdk" 86 87RDEPENDS_${PN}-dev = "" 88RRECOMMENDS_${PN}-dbg = "${PN}-dev (= ${EXTENDPKGV})" 89 90INHIBIT_DEFAULT_DEPS = "1" 91DEPENDS += "unifdef-native" 92
