Steam 回调在 Linux / GCC 编译期间触发警告

Steam Callbacks Trigger Warning During Compile In Linux / GCC

本文关键字：警告 编译 GCC 回调 Linux Steam      更新时间：2023-10-16

我已经在 Steamworks 集成上工作了一段时间，每次我在 Linux 上编译时，我所有的回调都会触发此警告。 每个一个，所以有一堵墙。话虽如此，回调工作得很好。

module.h: In member function 'virtual void Steam::CCallbackInternal__steam_api_call_completed::Run(void*)':
module.h:667:18: warning: offsetof within non-standard-layout type 'Steam' is conditionally-supported [-Winvalid-offsetof]
667 |   STEAM_CALLBACK(Steam, _steam_api_call_completed, SteamAPICallCompleted_t);

39 | #define _STEAM_CALLBACK_HELPER( _1, _2, SELECTED, ... )  _STEAM_CALLBACK_##SELECTED

当回调工作时，想知道是什么导致了这些警告以及如何修复它们。

我正在使用GCC/G ++ 9.2.1在Ubuntu Linux 19.10中进行编译，以供参考。

我不得不让他们沉默

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Winvalid-offsetof"
// my code
#pragma GCC diagnostic pop
