此目標不支持 VSC 運行代碼分析 __float128

Question

每次我在 C++ 項目中運行代碼分析時，我都會收到 __float128 is not supported on this target

是否有可能關閉這些 clang 錯誤？

我一直在尋找答案幾個小時，但找不到任何東西。

我的設置：Visual Studio Code V1.70.0、cmake、GCC v11.3.0.、clang 用 VSC、C++20 構建

整個錯誤：

Answer 1

我也遇到過同樣的情況。 但就我而言，gnu g++、mingw、C++11 或 17。我已經搜索了 2 天的答案，但找不到。 最初，該錯誤是由於“std_abs.h”header 文件中未聲明 __float128 的事實而產生的。 我通過在 main.cpp 的起始點添加一行來解決這個問題，就像這樣#define __STRICT_ANSI__因為如果__STRICT_ANSI__沒有定義，一些與 __float128 相關的代碼將被激活。

鑒於我的英語水平不佳，請參考此答案。 謝謝
