问题
It seems like the clang compiler flags are currently not compatible with the gnu standard library. Is there still a way to use coroutines?
回答1:
It's not quite accurate to say that GCC's header requires -fcoroutines, what it actually requires is for the __cpp_impl_coroutine macro to be defined by the compiler, indicating that the compiler supports C++20 Coroutines. With GCC, you activate that support by using -fcoroutines.
