Checking it now, this is what I disabled in the recent containers with recent enough distros/tollchains to build this, like debian:experimental: +# make -C /git/linux O=/tmp/build/linux allmodconfig && \ +# make -C /git/linux O=/tmp/build/linux headers_install && \ +# make -C /git/linux O=/tmp/build/linux samples/bpf/o [root@jouet bin]# dsh debian:experimental $ bash perfbuilder@91b0b6879760:/$ make -C /git/linux O=/tmp/build/linux allmodconfig make: Entering directory '/git/linux' make[1]: Entering directory '/tmp/build/linux' HOSTCC scripts/basic/fixdep GEN ./Makefile HOSTCC scripts/kconfig/conf.o SHIPPED scripts/kconfig/zconf.tab.c SHIPPED scripts/kconfig/zconf.lex.c SHIPPED scripts/kconfig/zconf.hash.c HOSTCC scripts/kconfig/zconf.tab.o HOSTLD scripts/kconfig/conf scripts/kconfig/conf --allmodconfig Kconfig # # configuration written to .config # make[1]: Leaving directory '/tmp/build/linux' make: Leaving directory '/git/linux' perfbuilder@91b0b6879760:/$ make -C /git/linux O=/tmp/build/linux headers_install make: Entering directory '/git/linux' make[1]: Entering directory '/tmp/build/linux' CHK include/generated/uapi/linux/version.h UPD include/generated/uapi/linux/version.h SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_32.h HOSTCC arch/x86/tools/relocs_32.o HOSTCC arch/x86/tools/relocs_64.o HOSTCC arch/x86/tools/relocs_common.o HOSTLD arch/x86/tools/relocs HOSTCC scripts/unifdef INSTALL usr/include/asm-generic/ (35 files) INSTALL usr/include/drm/ (22 files) INSTALL usr/include/linux/android/ (1 file) INSTALL usr/include/linux/byteorder/ (2 files) INSTALL usr/include/linux/caif/ (2 files) INSTALL usr/include/linux/can/ (5 files) INSTALL usr/include/linux/dvb/ (8 files) INSTALL usr/include/linux/hdlc/ (1 file) INSTALL usr/include/linux/hsi/ (2 files) INSTALL usr/include/linux/iio/ (2 files) INSTALL usr/include/linux/isdn/ (1 file) INSTALL usr/include/linux/mmc/ (1 file) INSTALL usr/include/linux/netfilter/ipset/ (4 files) INSTALL usr/include/linux/netfilter/ (87 files) INSTALL usr/include/linux/netfilter_arp/ (2 files) INSTALL usr/include/linux/netfilter_bridge/ (17 files) INSTALL usr/include/linux/netfilter_ipv4/ (9 files) INSTALL usr/include/linux/netfilter_ipv6/ (12 files) INSTALL usr/include/linux/nfsd/ (5 files) INSTALL usr/include/linux/raid/ (2 files) INSTALL usr/include/linux/spi/ (1 file) INSTALL usr/include/linux/sunrpc/ (1 file) INSTALL usr/include/linux/tc_act/ (15 files) INSTALL usr/include/linux/tc_ematch/ (4 files) INSTALL usr/include/linux/usb/ (11 files) INSTALL usr/include/linux/wimax/ (1 file) INSTALL usr/include/linux/ (452 files) INSTALL usr/include/misc/ (1 file) INSTALL usr/include/mtd/ (5 files) INSTALL usr/include/rdma/hfi/ (2 files) INSTALL usr/include/rdma/ (18 files) INSTALL usr/include/scsi/fc/ (4 files) INSTALL usr/include/scsi/ (4 files) INSTALL usr/include/sound/ (15 files) INSTALL usr/include/video/ (3 files) INSTALL usr/include/xen/ (4 files) INSTALL usr/include/uapi/ (0 file) /git/linux/scripts/Makefile.headersinst:62: *** Missing generated UAPI file ./arch/x86/include/generated/uapi/asm/unistd_64.h.
