I tried to change the kernel config file and then rebuild the kernel, but it fails like this on two up to date stable systems:
# make && make modules_install && make firmware_install HOSTCC scripts/kconfig/conf.o HOSTLD scripts/kconfig/conf scripts/kconfig/conf --silentoldconfig Kconfig 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 CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CC arch/x86/purgatory/purgatory.o AS arch/x86/purgatory/stack.o AS arch/x86/purgatory/setup-x86_64.o CC arch/x86/purgatory/sha256.o AS arch/x86/purgatory/entry64.o CC arch/x86/purgatory/string.o LD arch/x86/purgatory/purgatory.ro BIN2C arch/x86/purgatory/kexec-purgatory.c CC kernel/bounds.s CHK include/generated/bounds.h CHK include/generated/timeconst.h CC arch/x86/kernel/asm-offsets.s CHK include/generated/asm-offsets.h CALL scripts/checksyscalls.sh DESCEND objtool make[4]: *** No rule to make target '/usr/lib/gcc/x86_64-pc-linux- gnu/4.9.4/include/stddef.h', needed by '/usr/src/linux-4.9.16- gentoo/tools/objtool/fixdep.o'.

Running fix_libtool.sh on 4.9.4 doesn't change anything. :-/ Am I supposed to emerge a later version gentoo-sources to be able to build a kernel with gcc-5.4.0? -- Regards, Mick
