Please check the configure log.

I have found that entry line: "Boost.Cobalt: not building, can't include ."

config-x64-linux-out.log config-x64-linux-dbg-CMakeCache.txt.log

try_compile(
        BOOST_COBALT_HAS_COROUTINE_INCLUDE
        ${CMAKE_CURRENT_BINARY_DIR}
        ${CMAKE_CURRENT_LIST_DIR}/coroutine.cpp
        CXX_STANDARD 20
        CXX_STANDARD_REQUIRED 20
        OUTPUT_VARIABLE TRY_COMPILE_OUTPUT)

if (NOT BOOST_COBALT_HAS_COROUTINE_INCLUDE)
    message(STATUS "Boost.Cobalt: not building, can't include <coroutine>.")
    message(DEBUG ${TRY_COMPILE_OUTPUT})
    return()
endif()

Need to check why try_compile fails

check the *.yaml file in the subfolder CMakeFiles of the build folder

gcc-10 probably needs -fcoroutines in CXXFLAGS

[mezdej]

exactly as you said: 295 | #error "the coroutine header requires -fcoroutines" Can you guys fix it?

[mezdej]

Please add -fcoroutines in CXXFLAGS for gcc-10 @FrankXie05

[FrankXie05]

@mezdej I will do it. :)
