如何解决在克利翁未定义的参考`GetAcceptExSockAddrs的'（Boost.Asio的） [英] How to fix undefined reference to `GetAcceptExSockaddrs' (Boost.Asio) in CLion

问题描述

我已经包括升压1.61.0。我的C ++项目有<一个href=\"http://stackoverflow.com/questions/38767653/how-to-fix-undefined-reference-to-imp-wsacleanup-boost-asio-in-clion\">similar问题，我加了 target_link_libraries（WsServer WS2_32）和固定它。然后，另一个错误出现了。在code：<一href=\"https://github.com/zaphoyd/websocketpp/blob/master/examples/simple_broadcast_server/simple_broadcast_server.cpp\"相对=nofollow>的WebSocket ++例子：simple_broadcast_server.cpp 。我怎样才能解决这个问题？

解决方案

看来你必须添加 WSOCK32 来链接库，请参阅this帖子。

I have included Boost 1.61.0. My C++ project had similar problem, I added target_link_libraries(WsServer ws2_32) and fixed it. Then, another error appeared. The code: WebSocket++ examples: simple_broadcast_server.cpp . How I can fix it?

Console:

CMakeFiles\WsServer.dir/objects.a(main.cpp.obj): In function `boost::asio::detail::socket_ops::complete_iocp_accept(unsigned long long, void*, unsigned long, sockaddr*, unsigned long long*, unsigned long long, boost::system::error_code&)':

CMakeLists.txt:

cmake_minimum_required(VERSION 3.5)
project(WsServer)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")

set(SOURCE_FILES src/main.cpp)

include_directories(C:/Users/Marczak/CPPLibs)
find_package(Boost REQUIRED COMPONENTS filesystem)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(WsServer ${SOURCE_FILES})
target_link_libraries(WsServer ${Boost_LIBRARIES})

target_link_libraries(WsServer ws2_32)

解决方案

It seems that you have to add wsock32 to link libraries, see this post.
