Question

我正在尝试运行应使用Boost库的程序，并且收到以下消息：

Undefined symbols for architecture x86_64:
  "boost::detail::thread_data_base::~thread_data_base()", referenced from:
      boost::detail::thread_data<KeyBoardAndSendTask>::~thread_data() in echoClient.cpp.o
      boost::detail::thread_data<GetterTask>::~thread_data() in echoClient.cpp.o
  "boost::thread::join_noexcept()", referenced from:

  "boost::thread::detach()", referenced from:

  "boost::thread::interrupt()", referenced from:
      _main in echoClient.cpp.o
  "typeinfo for boost::detail::thread_data_base", referenced from:

  "vtable for boost::detail::thread_data_base", referenced from:
      boost::detail::thread_data_base::thread_data_base() in echoClient.cpp.o
  NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[3]: *** [Boost_Echo_Client] Error 1
make[2]: *** [CMakeFiles/Boost_Echo_Client.dir/all] Error 2
make[1]: *** [CMakeFiles/Boost_Echo_Client.dir/rule] Error 2
make: *** [Boost_Echo_Client] Error 2

有人知道我该如何解决吗？如果有帮助，我正在编程服务器和客户端程序。

这是我的cmakeList：

cmake_minimum_required(VERSION 3.12)
project(Boost_Echo_Client)

set(CMAKE_CXX_STANDARD 14)

include_directories(include)

add_executable(Boost_Echo_Client
        include/connectionHandler.h
        src/connectionHandler.cpp
        src/echoClient.cpp
        makefile)



find_package(Boost COMPONENTS system filesystem REQUIRED)
IF (Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIR})
    target_link_libraries(Boost_Echo_Client
            ${Boost_FILESYSTEM_LIBRARY}
            ${Boost_SYSTEM_LIBRARY}
            )
endif()

恶作剧！
