SUMMARY = "Sanitized set of kernel headers for the C library's use" HOMEPAGE = "https://www.kernel.org/" DESCRIPTION = "Designed to maintain an Application Programming Interface (API) stable version of the Linux headers" SECTION = "devel" LICENSE = "GPLv2" ######################################################################### #### PLEASE READ ######################################################################### # # You're probably looking here thinking you need to create some new copy # of linux-libc-headers since you have your own custom kernel. To put # this simply, you DO NOT. # # Why? These headers are used to build the libc. If you customise the # headers you are customising the libc and the libc becomes machine # specific. Most people do not add custom libc extensions to the kernel # and have a machine specific libc. # # But you have some kernel headers you need for some driver? That is fine # but get them from STAGING_KERNEL_BUILDDIR where the kernel installs itself. # This will make the package using them machine specific but this is much # better than having a machine specific C library. This does mean your # recipe needs a # do_configure[depends] += "virtual/kernel:do_shared_workdir" # but again, that is fine and makes total sense. # # There can also be a case where your kernel extremely old and you want # an older libc ABI for that old kernel. The headers installed by this # recipe should still be a standard mainline kernel, not your own custom # one. # # -- RP LIC_FILES_CHKSUM ?= "file://COPYING;md5=bbea815ee2795b2f4230826c0c6b8814" RECIPE_NO_UPDATE_REASON = "Recipe is updated through a separate process" python __anonymous () { major = d.getVar("PV").split('.')[0] if major == "3": d.setVar("HEADER_FETCH_VER", "3.0") elif major == "4": d.setVar("HEADER_FETCH_VER", "4.x") elif major == "5": d.setVar("HEADER_FETCH_VER", "5.x") else: d.setVar("HEADER_FETCH_VER", "2.6") } MAJ_VER = "${@oe.utils.trim_version("${PV}", 2).split('.')[0]}" MIN_VER = "${@oe.utils.trim_version("${PV}", 2).split('.')[1]}" inherit kernel-arch pkgconfig multilib_header KORG_ARCHIVE_COMPRESSION ?= "xz" SRC_URI = "${KERNELORG_MIRROR}/linux/kernel/v${HEADER_FETCH_VER}/linux-${PV}.tar.${KORG_ARCHIVE_COMPRESSION}" UPSTREAM_CHECK_URI = "https://www.kernel.org/" S = "${WORKDIR}/linux-${PV}" EXTRA_OEMAKE = " HOSTCC="${BUILD_CC}" HOSTCPP="${BUILD_CPP}"" do_configure[noexec] = "1" do_compile[noexec] = "1" do_install() { oe_runmake headers_install INSTALL_HDR_PATH=${D}${exec_prefix} # Kernel should not be exporting this header rm -f ${D}${exec_prefix}/include/scsi/scsi.h # The ..install.cmd conflicts between various configure runs find ${D}${includedir} -name ..install.cmd | xargs rm -f } do_install:append:aarch64 () { do_install_armmultilib } do_install:append:arm () { do_install_armmultilib } do_install:append:armeb () { do_install_armmultilib } do_install_armmultilib () { if [ ${MAJ_VER} -gt 5 ]; then ARM_KVM_HEADER="" else if [ ${MAJ_VER} -eq 5 ] && [ ${MIN_VER} -ge 8 ]; then ARM_KVM_HEADER="" else ARM_KVM_HEADER="asm/kvm.h" fi fi oe_multilib_header asm/auxvec.h asm/bitsperlong.h asm/byteorder.h asm/fcntl.h asm/hwcap.h asm/ioctls.h $ARM_KVM_HEADER asm/kvm_para.h asm/mman.h asm/param.h asm/perf_regs.h asm/bpf_perf_event.h oe_multilib_header asm/posix_types.h asm/ptrace.h asm/setup.h asm/sigcontext.h asm/siginfo.h asm/signal.h asm/stat.h asm/statfs.h asm/swab.h asm/types.h asm/unistd.h } BBCLASSEXTEND = "nativesdk" RDEPENDS:${PN}-dev = "" RRECOMMENDS:${PN}-dbg = "${PN}-dev (= ${EXTENDPKGV})" INHIBIT_DEFAULT_DEPS = "1" DEPENDS += "unifdef-native bison-native rsync-native"
