From: Neil Horman Date: Mon, 22 Jan 2018 01:48:05 +0000 (-0500) Subject: mk: add experimental tag check X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a6ec31597a0b;p=dpdk.git mk: add experimental tag check Add checks during build to ensure that all symbols in the EXPERIMENTAL version map section have __experimental tags on their definitions, and enable the warnings needed to announce their use. Also add an ALLOW_EXPERIMENTAL_APIS define to allow individual libraries and files to declare the acceptability of experimental api usage Signed-off-by: Neil Horman Acked-by: Thomas Monjalon --- diff --git a/app/pdump/Makefile b/app/pdump/Makefile index e6b9eea91b..bd3c208195 100644 --- a/app/pdump/Makefile +++ b/app/pdump/Makefile @@ -7,6 +7,7 @@ ifeq ($(CONFIG_RTE_LIBRTE_PDUMP),y) APP = dpdk-pdump +CFLAGS += -DALLOW_EXPERIMENTAL_API CFLAGS += $(WERROR_FLAGS) #
