To put 13*# this simply, you DO NOT. 14*# 15*# Why? These headers are used to build the libc. If you customise the 16*# headers you are customising the libc and the libc becomes machine 17*# specific. Most people do not add custom libc extensions to the kernel 18*# and have a machine specific libc. 19*# 20*# But you have some kernel headers you need for some driver? That is fine 21*# but get them from STAGING_KERNEL_BUILDDIR where the kernel installs itself. 22*# This will make the package using them machine specific but this is much 23*# better than having a machine specific C library. This does mean your 24*# recipe needs a 25*# do_configure[depends] += "virtual/kernel:do_shared_workdir" 26*# but again, that is fine and makes total sense. 27*# 28*# There can also be a case where your kernel extremely old and you want 29*# an older libc ABI for that old kernel. The headers installed by this 30*# recipe should still be a standard mainline kernel, not your own custom 31*# one. 32*# 33*# -- RP 34* 35*LIC_FILES_CHKSUM ?= "file://COPYING;md5=bbea815ee2795b2f4230826c0c6b8814" 36* 37*RECIPE_NO_UPDATE_REASON = "Recipe is updated through a separate process" 38* 39*python __anonymous () { 40* major = d.getVar("PV").split('.')[0] 41* if major == "3": 42* d.setVar("HEADER_FETCH_VER", "3.0") 43* elif major == "4": 44* d.setVar("HEADER_FETCH_VER", "4.x") 45* elif major == "5": 46* d.setVar("HEADER_FETCH_VER", "5.x") 47* elif major == "6": 48* d.setVar("HEADER_FETCH_VER", "6.x") 49* else: 50* d.setVar("HEADER_FETCH_VER", "2.6") 51*} 52* 53*MAJ_VER = "${@oe.utils.trim_version("${PV}", 2).split('.')[0]}" 54*MIN_VER = "${@oe.utils.trim_version("${PV}", 2).split('.')[1]}" 55* 56*inherit kernel-arch pkgconfig multilib_header 57* 58*KORG_ARCHIVE_COMPRESSION ?= "xz" 59* 60*SRC_URI = "${KERNELORG_MIRROR}/linux/kernel/v${HEADER_FETCH_VER}/linux-${PV}.tar.${KORG_ARCHIVE_COMPRESSION}" 61*UPSTREAM_CHECK_URI = "https://www.kernel.org/" 62* 63*S = "${WORKDIR}/linux-${PV}" 64* 65*EXTRA_OEMAKE = " HOSTCC="${BUILD_CC}" HOSTCPP="${BUILD_CPP}"" 66* 67*do_configure[noexec] = "1" 68* 69*do_compile[noexec] = "1" 70* 71*do_install() { 72* oe_runmake headers_install INSTALL_HDR_PATH=${D}${exec_prefix} 73* # Kernel should not be exporting this header 74* rm -f ${D}${exec_prefix}/include/scsi/scsi.h 75* 76* # The ..install.cmd conflicts between various configure runs 77* find ${D}${includedir} -name ..install.cmd | xargs rm -f 78*} 79* 80*do_install:append:aarch64 () { 81* do_install_armmultilib 82*} 83* 84*do_install:append:arm () { 85* do_install_armmultilib 86*} 87* 88*do_install:append:armeb () { 89* do_install_armmultilib 90*} 91* 92*do_install_armmultilib () { 93* if [ ${MAJ_VER} -gt 5 ]; then 94* ARM_KVM_HEADER="" 95* else 96* if [ ${MAJ_VER} -eq 5 ] && [ ${MIN_VER} -ge 8 ]; then 97* ARM_KVM_HEADER="" 98* else 99* ARM_KVM_HEADER="asm/kvm.h" 100* fi 101* fi 102* oe_multilib_header asm/auxvec.h asm/bitsperlong.h asm/byteorder.h asm/fcntl.h asm/hwcap.h asm/ioctls.h $ARM_KVM_HEADER asm/kvm_para.h asm/mman.h asm/param.h asm/perf_regs.h asm/bpf_perf_event.h 103* oe_multilib_header asm/posix_types.h asm/ptrace.h asm/setup.h asm/sigcontext.h asm/siginfo.h asm/signal.h asm/stat.h asm/statfs.h asm/swab.h asm/types.h asm/unistd.h 104*} 105* 106*BBCLASSEXTEND = "nativesdk" 107* 108*DEV_PKG_DEPENDENCY = "" 109*RRECOMMENDS:${PN}-dbg = "${PN}-dev (= ${EXTENDPKGV})" 110* 111*INHIBIT_DEFAULT_DEPS = "1" 112*DEPENDS += "unifdef-native bison-native rsync-native" 113*
