此目标不支持 VSC 运行代码分析 __float128

Question

每次我在 C++ 项目中运行代码分析时，我都会收到 __float128 is not supported on this target

是否有可能关闭这些 clang 错误？

我一直在寻找答案几个小时，但找不到任何东西。

我的设置：Visual Studio Code V1.70.0、cmake、GCC v11.3.0.、clang 用 VSC、C++20 构建

整个错误：

Answer 1

我也遇到过同样的情况。 但就我而言，gnu g++、mingw、C++11 或 17。我已经搜索了 2 天的答案，但找不到。 最初，该错误是由于“std_abs.h”header 文件中未声明 __float128 的事实而产生的。 我通过在 main.cpp 的起始点添加一行来解决这个问题，就像这样#define __STRICT_ANSI__因为如果__STRICT_ANSI__没有定义，一些与 __float128 相关的代码将被激活。

鉴于我的英语水平不佳，请参考此答案。 谢谢
