Build fail can be observed while the kvm-unit-tests builds on Ubuntu Yakkety/Zesty release: /usr/bin/ld: x86/cstart64.o: relocation R_X86_64_32 against `.data' can not be used when making a shared object; recompile with -fPIC and can be fixed by adding "-fno-pic" and "-no-pie" option. There are other discussions: - gcc-6 6.2.0-7 breaks kernel build if stack protection is enabled https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=841368 - [yakkety,RFC,v1] disable -pie when gcc has it enabled by default https://patchwork.ozlabs.org/patch/616621/ - https://wiki.ubuntu.com/YakketyYak/ReleaseNotes#GCC Signed-off-by: Gavin Guo <gavin.guo@xxxxxxxxxxxxx> Signed-off-by: Hsiangkai Wang <hsiangkai@xxxxxxxxx> Signed-off-by: Cole Wang <cole945@xxxxxxxxx> Tested-by: Po-Hsu Lin <po-hsu.lin@xxxxxxxxxxxxx> --- Makefile | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/Makefile b/Makefile index a32333b0928e..4c9fbfbb6714 100644 --- a/Makefile +++ b/Makefile @@ -51,10 +51,14 @@ fomit_frame_pointer := $(call cc-option, $(frame-pointer-flag), "") fnostack_protector := $(call cc-option, -fno-stack-protector, "") fnostack_protector_all := $(call cc-option, -fno-stack-protector-all, "") wno_frame_address := $(call cc-option, -Wno-frame-address, "") +fno_pic := $(call cc-option, -fno-pic, "") +no_pie := $(call cc-option, -no-pie, "") CFLAGS += $(fomit_frame_pointer) CFLAGS += $(fno_stack_protector) CFLAGS += $(fno_stack_protector_all) CFLAGS += $(wno_frame_address) +CFLAGS += $(fno_pic) +CFLAGS += $(no_pie) CXXFLAGS += $(CFLAGS) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
