As a follow-up tp my previous comment #12 (https://bugs.launchpad.net/ubuntu/+source/xtables-addons/+bug/1830961/comments/12), I have discovered 2 new facts: - I am not able to build dpdk 19.05 on the same system anymore, (cf. build log), unless I modify the gcc symlink to point to gcc-8 instead of gcc-9 - however, the xtables -addons issue encountered on the previous system has not been seen on 2 other Ubuntu Eoan platforms with the exact same versions of: + gcc-9 (and/usr/bin/gcc -> gcc-9) + linux kernels + xtables-addons-dkms/common
** Attachment added: "DPDK 19.05 build log" https://bugs.launchpad.net/ubuntu/+source/xtables-addons/+bug/1830961/+attachment/5276174/+files/dpdk_19.05_amd64.build -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1830961 Title: Kernels & kernel drivers fail to build with gcc-9 [error: ‘-mindirect- branch’ and ‘-fcf-protection’ are not compatible] Status in gcc-9 package in Ubuntu: Invalid Status in linux package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-430 package in Ubuntu: Fix Committed Status in virtualbox package in Ubuntu: Confirmed Status in xtables-addons package in Ubuntu: New Bug description: Compiling kernels & kernel modules fails due to these errors: ./include/linux/compiler.h:193:1: error: ‘-mindirect-branch’ and ‘-fcf-protection’ are not compatible (This happens with any kernel modules.) This appears to be due to the changes in 9.1.0-3ubuntu1 enabling -fcf- protection by default on 19.10's gcc-9. Switching to gcc-8 allows compilation to proceed.
