如何用clang 11编译Windows API C++代码

Question

我刚刚从llvm官方网站下载了llvm-11-win64(我需要使用clang而不是mingw-g++(。我正在尝试编译一个测试C++文件，该文件包括<windows.h>(头文件取自mingw64安装(

// test.cpp
#include <windows.h>
bool WINAPI DllMain(HINSTANCE hModule, DWORD fwdReason, LPVOID reserved)
{
return TRUE;
}

典型的命令行编译会出现错误，我应该做一些不同的操作吗？

$ clang++ -I "/c/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/x86_64-w64-mingw32/include/" -c test.cpp

头文件取自mingw64安装

Microsoft提供了可与Clang一起使用的官方Windows标头(如果我没有记错的话，Microsoft不久前就开始在Visual Studio中提供Clang(。
