Package: gcc-6 Version: 6.2.0-9 Severity: important Hi,
Since 6.2.0-7, building the linux kernel (4.8.3 in my case) with --fstack-protector-strong or -fstack-protector fails. I've tested wit h 6.2.0-7 and 6.2.0-9. The I've reverted to 6.2.0-6 and it works fine. -- System Information: Debian Release: stretch/sid APT prefers buildd-unstable APT policy: (500, 'buildd-unstable'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernelving directory '/usr/src/linux-4.8.3' make EXTRAVERSION=-i7-1 ARCH=x86_64 prepare make[2]: Entering directory '/usr/src/linux-4.8.3' scripts/kconfig/conf --silentoldconfig Kconfig SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/asm/unistd_32_ia32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/asm/unistd_64_x32.h SYSTBL arch/x86/entry/syscalls/../../include/generated/asm/syscalls_64.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_32.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_64.h SYSHDR arch/x86/entry/syscalls/../../include/generated/uapi/asm/unistd_x32.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 CHK include/config/kernel.release UPD include/config/kernel.release Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler Makefile:1048: recipe for target 'prepare-compiler-check' failed make[2]: *** [prepare-compiler-check] Error 1 make[2]: Leaving directory '/usr/src/linux-4.8.3' debian/ruleset/targets/common.mk:194: recipe for target 'debian/stamp/conf/kernel-conf' failed --- Cannot use CONFIG_CC_STACKPROTECTOR_REGULAR: -fstack-protector not supported by compiler Makefile:1048: recipe for target 'prepare-compiler-check' failed make[2]: *** [prepare-compiler-check] Error 1 make[2]: Leaving directory '/usr/src/linux-4.8.3' debian/ruleset/targets/common.mk:194: recipe for target 'debian/stamp/conf/kernel-conf' failed ---: Linux 4.8.3-i7-0.1 (SMP w/8 CPU cores; PREEMPT) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages gcc-6 depends on: ii binutils 2.27-9 ii cpp-6 6.2.0-9 ii gcc-6-base 6.2.0-9 ii libc6 2.24-5 ii libcc1-0 6.2.0-9 ii libgcc-6-dev 6.2.0-9 ii libgcc1 1:6.2.0-9 ii libgmp10 2:6.1.1+dfsg-1 ii libisl15 0.17.1-1 ii libmpc3 1.0.3-1 ii libmpfr4 3.1.5-1 ii libstdc++6 6.2.0-9 ii zlib1g 1:1.2.8.dfsg-2+b1 Versions of packages gcc-6 recommends: ii libc6-dev 2.24-5 Versions of packages gcc-6 suggests: pn gcc-6-doc <none> pn gcc-6-locales <none> ii gcc-6-multilib 6.2.0-9 pn libasan3-dbg <none> pn libatomic1-dbg <none> pn libcilkrts5-dbg <none> pn libgcc1-dbg <none> pn libgomp1-dbg <none> pn libitm1-dbg <none> pn liblsan0-dbg <none> pn libmpx2-dbg <none> pn libquadmath0-dbg <none> pn libtsan0-dbg <none> pn libubsan0-dbg <none> -- no debconf information
