我正在尝试使用 MinGW STL（clang 和 mingw 的最新版本）在 windows 下使用 Clang 编译一个简单的 dll。如您所见，我禁用了 ms 兼容模式和硬编码的 VS 标头。包含 MinGW STL 映射标头时出现以下错误：

这些函数在 MinGW 中stdio.h和/或wchar.h在__MSVCRT__定义宏时声明。MinGW 编译器定义了__MSVCRT__它何时重新构建msvcrt.dll运行时而不是旧的crtdll运行时（我认为它几乎不再使用了）。

我不知道 clang 是否会定义该宏或在什么条件下会定义（或者即使 clang 将链接到msvcrt.dll）。

您可以尝试-D__MSVCRT__=1在 clang 命令行中添加 a 以查看是否可以正常工作。
