From: Flavia Musatescu Date: Wed, 3 Jul 2019 09:23:43 +0000 (+0100) Subject: telemetry: fix build with gcc 9 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5c0bdc32034b2464305ee55b5829a45451f221ef;p=dpdk.git telemetry: fix build with gcc 9 Suppress the unaligned packed member address warnings by extending the telemetry library build flags with -Wno-address-of-packed-member option, through the WERROR_FLAGS makefile variable. With this change additional warnings are turned on to be treated as errors, which causes the following build issues to be seen: - no previous prototype [-Werror=missing-prototypes] - initialization discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers] - old-style function definition [-Werror=old-style-definition] - variable may be used before its value is set (when using icc compiler). Fixes: 0fe3a37924d4 ("telemetry: format json response when sending stats") Fixes: ee5ff0d3297e ("telemetry: add client feature and sockets") Fixes: 8877ac688b52 ("telemetry: introduce infrastructure") Fixes: 1b756087db93 ("telemetry: add parser for client socket messages") Fixes: fff6df7bf58e ("telemetry: fix using ports of different types") Fixes: 4080e46c8078 ("telemetry: support global metrics") Cc: stable@dpdk.org Signed-off-by: Reshma Pattan Signed-off-by: Flavia Musatescu Acked-by: Kevin Laatz --- diff --git a/lib/librte_telemetry/Makefile b/lib/librte_telemetry/Makefile index 1a05069132..1b3fe05475 100644 --- a/lib/librte_telemetry/Makefile +++ b/lib/librte_telemetry/Makefile @@ -7,7 +7,7 @@ include $(RTE_SDK)/mk/rte.vars.mk LIB = librte_telemetry.a CFLAGS += -O3 -CFLAGS += -I$(SRCDIR) +CFLAGS += $(WERROR_FLAGS) -I$(SRCDIR) CFLAGS += -DALLOW_EXPERIMENTAL_API LDLIBS += -lrte_eal -lrte_ethdev diff --git a/lib/librte_telemetry/meson.build b/lib/librte_telemetry/meson.build index 3e7db4f193..26a331140b 100644 --- a/lib/librte_telemetry/meson.build +++ b/lib/librte_telemetry/meson.build @@ -2,7 +2,7 @@ # Copyright(c) 2018 Intel Corporation sources = files('rte_telemetry.c', 'rte_telemetry_parser.c', 'rte_telemetry_parser_test.c') -headers = files('rte_telemetry.h', 'rte_telemetry_internal.h', 'rte_telemetry_parser.h', 'rte_telemetry_parser_test.h') +headers = files('rte_telemetry.h', 'rte_telemetry_internal.h', 'rte_telemetry_parser.h') deps += ['metrics', 'ethdev'] cflags += '-DALLOW_EXPERIMENTAL_API' diff --git a/lib/librte_telemetry/rte_telemetry.c b/lib/librte_telemetry/rte_telemetry.c index 9819b228bc..eb20cc6515 100644 --- a/lib/librte_telemetry/rte_telemetry.c +++ b/lib/librte_telemetry/rte_telemetry.c @@ -18,7 +18,6 @@ #include "rte_telemetry.h" #include "rte_telemetry_internal.h" #include "rte_telemetry_parser.h" -#include "rte_telemetry_parser_test.h" #include "rte_telemetry_socket_tests.h" #define BUF_SIZE 1024 @@ -32,13 +31,13 @@ static telemetry_impl *static_telemetry;
