Hi there, I am trying to compile the asio co-routine example but as far as I can tell boost is looking for an <experimental/coroutine> header that does not exist on my system. I am using boost 1.71 and gcc on ubuntu 20.04. I tried both stock gcc (v9 on ubuntu) which does not have a coroutine header and gcc 10 which does have it but not under the experimental directory. Here is the output with gcc 10: /usr/lib/ccache/g++ -I../../src -g -Wall -pedantic -Wextra -Werror -DASIO_HAS_CO_AWAIT -DBOOST_ASIO_HAS_CO_AWAIT -fcoroutines --std=c++2a -fdiagnostics-color -MD -MT CMakeFiles/mcbridge.dir /src/main.cpp.o -MF CMakeFiles/mcbridge.dir/src/main.cpp.o.d -o CMakeFiles/mcbridge.dir/src/main.cpp.o -c ../../src/main.cpp In file included from /usr/include/boost/asio/co_spawn.hpp:22, from ../../src/main.cpp:4: /usr/include/boost/asio/awaitable.hpp:22:10: fatal error: experimental/coroutine: No such file or directory 22 | #include <experimental/coroutine> Any ideas on how to compile this example?
