See https://gcc.gnu.org/gcc-10/porting_to.html for more informations. I didn't put -fcommon to CFLAGS since: Compiling with -fno-common is useful on targets for which it provides better performance, or if you wish to verify that the program will work on other systems that always treat uninitialized variable definitions this way. from gcc man page Timothy Redaelli (3): examples/vhost_blk: fix building with GCC 10 examples/eventdev_pipeline: fix building with GCC 10 examples/qos_sched: fix building with GCC 10 examples/eventdev_pipeline/main.c | 2 ++ examples/eventdev_pipeline/pipeline_common.h | 4 ++-- examples/qos_sched/cfg_file.c | 3 +++ examples/qos_sched/main.h | 4 ++-- examples/vhost_blk/vhost_blk.c | 2 ++ examples/vhost_blk/vhost_blk.h | 4 ++-- 6 files changed, 13 insertions(+), 6 deletions(-) --=20 2.24.1
