From 9eff97861b88999428d1254f95c83d94a2e95944 Mon Sep 17 00:00:00 2001 From: Derek Mauro Date: Thu, 9 Jun 2022 07:49:38 -0700 Subject: Fix C++17 constexpr storage deprecation warnings This change introduces the symbol ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL to guard redundant declarations of static constexpr data members that are needed prior to C++17. This change also introduces the symbol ABSL_INTERNAL_CPLUSPLUS_LANG, which is supposed to be set to the same value as __cplusplus, except it uses _MSVC_LANG on MSVC so that the value is correct on MSVC. Neither of these new symbols should be used outside of Abseil. Fixes #1191 PiperOrigin-RevId: 453923908 Change-Id: I1316c52c19fa0c168b93cced0c817e4cb7c9c862 --- absl/status/status.cc | 2 ++ 1 file changed, 2 insertions(+) (limited to 'absl/status') diff --git a/absl/status/status.cc b/absl/status/status.cc index c66009d6..89749a52 100644 --- a/absl/status/status.cc +++ b/absl/status/status.cc @@ -195,7 +195,9 @@ const std::string* Status::EmptyString() { return &empty.str; } +#ifdef ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL constexpr const char Status::kMovedFromString[]; +#endif const std::string* Status::MovedFromString() { static std::string* moved_from_string = new std::string(kMovedFromString); -- cgit v1.2.3
