I believe there's a fix for this about to come out in boost 1.73 Until then it will work with clang9 -fcoroutines-ts -stdlib=libc++ It's because gcc went straight to the c++20 version of coroutines without stopping fot coroutines.ts.

Hi there, I am trying to compile the asio co-routine example but as far as I can tell boost is looking for an
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
Any ideas on how to compile this example? _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org https://lists.boost.org/mailman/listinfo.cgi/boost-users
