Exported header files used by applications should allow the strictest compiler flags. Language extensions used in many places must be explicitly marked to avoid warnings and compilation failures.
Unnamed structs/unions are allowed since C11, however many compiler versions do not use this mode by default. This commit prevents the following errors: error: ISO C99 doesn't support unnamed structs/unions error: struct has no named members Signed-off-by: Adrien Mazarguil <adrien.mazarguil at 6wind.com> --- lib/librte_cryptodev/rte_crypto.h | 3 +++ lib/librte_cryptodev/rte_crypto_sym.h | 4 ++++ lib/librte_cryptodev/rte_cryptodev.h | 5 +++++ lib/librte_cryptodev/rte_cryptodev_pmd.h | 2 ++ lib/librte_eal/common/include/arch/ppc_64/rte_cycles.h | 3 +++ lib/librte_eal/common/include/arch/x86/rte_atomic_32.h | 3 +++ lib/librte_eal/common/include/arch/x86/rte_cycles.h | 3 +++ lib/librte_eal/common/include/rte_common.h | 7 +++++++ lib/librte_eal/common/include/rte_devargs.h | 1 + lib/librte_eal/common/include/rte_interrupts.h | 2 ++ lib/librte_eal/common/include/rte_memory.h | 1 + lib/librte_eal/common/include/rte_memzone.h | 2 ++ lib/librte_eal/linuxapp/eal/include/exec-env/rte_interrupts.h | 1 + lib/librte_hash/rte_thash.h | 4 ++++ lib/librte_lpm/rte_lpm.h | 1 + lib/librte_mbuf/rte_mbuf.h | 5 +++++ lib/librte_pipeline/rte_pipeline.h | 3 +++ lib/librte_timer/rte_timer.h | 2 ++ 18 files changed, 52 insertions(+) diff --git a/lib/librte_cryptodev/rte_crypto.h b/lib/librte_cryptodev/rte_crypto.h index 5bc3eaa..11a7759 100644 --- a/lib/librte_cryptodev/rte_crypto.h +++ b/lib/librte_cryptodev/rte_crypto.h @@ -40,6 +40,8 @@ * */ +#include <rte_common.h> + #ifdef __cplusplus extern "C" { #endif @@ -111,6 +113,7 @@ struct rte_crypto_op { void *opaque_data;
