With VERBOSE=1, this error was seen in debug mode with gcc 9.1: In file included from /tmp/dpdk.auto-config-h.sh.c.w0VWMi:1: In file included from rdma-core/build/include/infiniband/mlx5dv.h:47: In file included from rdma-core/build/include/infiniband/verbs.h:46: In file included from rdma-core/build/include/infiniband/verbs_api.h:66: In file included from rdma-core/build/include/infiniband/ib_user_ioctl_verbs.h:38: include/rdma/ib_user_verbs.h:161:28: fatal error: zero size arrays are an extension [-Wzero-length-array] __aligned_u64 driver_data0; ^ 1 error generated. As a result, buildtools/auto-config-h.sh was not generating a correct autoconf file, so the compilation was generating such error: fatal error: redefinition of 'mlx5_ib_uapi_flow_action_packet_reformat_type' It is fixed by disabling -pedantic option when calling auto-config-h.sh from the makefile-based system.
