wondows使用clang-cl编译代码报The ＜experimental/coroutine＞, ＜experimental/generator＞ ...

使用clang-cl编译

代码编译遇到

The <experimental/coroutine>, <experimental/generator>, and <experimental/resumable> headers do not support Clang,
      but the C++20 <coroutine> header does

这个错误只需要

clang-cl  /D_SILENCE_CLANG_COROUTINE_MESSAGE test.cpp

原因是 microsoft/STL coroutine这个文件里有一行

#if defined(__clang__) && !defined(_SILENCE_CLANG_COROUTINE_MESSAGE)
#error The <experimental/coroutine>, <experimental/generator>, and <experimental/resumable> \
headers do not support Clang, but the C++20 <coroutine> header does.
#endif // defined(__clang__) && !defined(_SILENCE_CLANG_COR

OUTINE_MESSAGE)

所以只需要用-D选项加上_SILENCE_CLANG_COROUTINE_MESSAGE

解决问题。
