When cross-compiling with v5.12-rc3, prepare fails[1] build of vdso at the objcopy stage since it seems to be using the local host's objcopy rather than the cross-compile version we want it to use.
This can be trivially reproduced in a localbuild of the kernel following the build parameters provided in the process[2] Lets fix this by passing OBJCOPY over to the kernel.

This is a different problem and is not resolved with https://lists.openembedded.org/g/openembedded-core/message/149943 2. Though reproduced during a dunfell build, this should probably apply else where as well. 3. I have'nt been able to cleanly bisect things, but my best guess was that this might be a consequence of kernel fixup exposing this. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a5b8ca97fbf8300a5e21c393df25ce6f521e7939 meta/classes/kernel-arch.bbclass | 3 +++ meta/recipes-kernel/make-mod-scripts/make-mod-scripts_1.0.bb | 2 +- 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/meta/classes/kernel-arch.bbclass b/meta/classes/kernel-arch.bbclass index 07ec242e63bb..3d25fc7ac531 100644 --- a/meta/classes/kernel-arch.bbclass +++ b/meta/classes/kernel-arch.bbclass @@ -60,9 +60,12 @@ TARGET_LD_KERNEL_ARCH ?= "" HOST_LD_KERNEL_ARCH ?= "${TARGET_LD_KERNEL_ARCH}" TARGET_AR_KERNEL_ARCH ?= "" HOST_AR_KERNEL_ARCH ?= "${TARGET_AR_KERNEL_ARCH}" +TARGET_OBJCOPY_KERNEL_ARCH ?= "" +HOST_OBJCOPY_KERNEL_ARCH ?= "${TARGET_OBJCOPY_KERNEL_ARCH}" KERNEL_CC = "${CCACHE}${HOST_PREFIX}gcc ${HOST_CC_KERNEL_ARCH} -fuse-ld=bfd ${DEBUG_PREFIX_MAP} -fdebug-prefix-map=${STAGING_KERNEL_DIR}=${KERNEL_SRC_PATH}" KERNEL_LD = "${CCACHE}${HOST_PREFIX}ld.bfd ${HOST_LD_KERNEL_ARCH}" KERNEL_AR = "${CCACHE}${HOST_PREFIX}ar ${HOST_AR_KERNEL_ARCH}" +KERNEL_OBJCOPY = "${CCACHE}${HOST_PREFIX}objcopy ${HOST_OBJCOPY_KERNEL_ARCH}" TOOLCHAIN = "gcc" diff --git a/meta/recipes-kernel/make-mod-scripts/make-mod-scripts_1.0.bb b/meta/recipes-kernel/make-mod-scripts/make-mod-scripts_1.0.bb index 87b7d240f51a..2d73e8093c2e 100644 --- a/meta/recipes-kernel/make-mod-scripts/make-mod-scripts_1.0.bb +++ b/meta/recipes-kernel/make-mod-scripts/make-mod-scripts_1.0.bb @@ -25,7 +25,7 @@ EXTRA_OEMAKE = " HOSTCC="${BUILD_CC} ${BUILD_CFLAGS} ${BUILD_LDFLAGS}" HOSTCPP=" do_configure() { unset CFLAGS CPPFLAGS CXXFLAGS LDFLAGS for t in prepare scripts_basic scripts; do - oe_runmake CC="${KERNEL_CC}" LD="${KERNEL_LD}" AR="${KERNEL_AR}" \ + oe_runmake CC="${KERNEL_CC}" LD="${KERNEL_LD}" AR="${KERNEL_AR}" OBJCOPY="${KERNEL_OBJCOPY}"\ -C ${STAGING_KERNEL_DIR} O=${STAGING_KERNEL_BUILDDIR} $t done } -- 2.31.0
