<pre>Compiling a .cpp file that uses the coroutine library with the command.
clang-11 -std=c++20 -stdlib=libstdc++ main.cpp
The error is as follows:
/usr/lib/gcc/x86_64-linux-gnu/10/../../../../include/c++/10/coroutine:295:2:
error: "the coroutine header requires -fcoroutines"
#error "the coroutine header requires -fcoroutines"
Adding the -fcoroutine flag doesn't help:
clang-11 -std=c++20 -stdlib=libstdc++ main.cpp -fcoroutines
which generates the error:
clang-11: error: unknown argument: '-fcoroutines'</pre>
