我正在接近这组库，因为我需要为我的大学考试创建一个个人项目，并且我想做一些具有网络功能的事情。我已经有一本关于这个特定库的书，但现在我无法在我的项目中链接它（我的书只解释了如何在 linux 上将它与 GCC 链接，但我正在 Windows 10 上将 CLion 与 MinGW 结合起来）。当我像这样编译一个简单的空项目时：

#include <boost/asio.h>

int main ( int argc, char ** argv ) {

   return 0;
}

我得到了这个令人印象深刻的错误：

   CMakeFiles\Hello.dir/objects.a(main.cpp.obj): In function `_static_initialization_and_destruction_0':
   C:/boost_1_63_0/boost/system/error_code.hpp:221: undefined reference to `boost::system::generic_category()'

这是我的 CMakeLists.txt

   cmake_minimum_required(VERSION 3.6)
   project(Hello)


   set(CMAKE_CXX_STANDARD 14)

   set(SRC_FILES main.cpp)
   include_directories(C:\\boost_1_63_0)
   link_directories(C:\\boost_1_63_0)

   find_package(BOOST 1.63.0 REQUIRED)

   add_executable(Hello ${SRC_FILES})

我该如何解决这个问题？提前致谢！

编辑

我更新了我的 CMakeLists.txt，如下所示：

cmake_minimum_required(VERSION 3.8.0)
project(Hello)


set(CMAKE_CXX_STANDARD 14)

set(SRC_FILES main.cpp)

set(BOOST_ROOT C:\\boost_1_63_0)
find_package(Boost 1.63.0 COMPONENTS system REQUIRED)
find_library(WS2_32_LIBRARY ws2_32)

link_directories(C:\\boost_1_63_0)
link_libraries(${BOOST_LIBRARIES})

add_executable(Hello ${SRC_FILES})
target_link_libraries(Hello ${WS2_32_LIBRARY} ${BOOST_LIBRARIES})

现在我没有收到任何错误，无论如何，当我告诉我的程序时：

#include <boost/asio.hpp>

升压变红，静态分析器告诉我“找不到升压”。现在问题出在哪里？谢谢！

你应该用Boost.Systemand链接Winsock，所以在你的 CMakeLists.txt 中添加这样的东西：

find_package(Boost COMPONENTS system REQUIRED)
find_library(WS2_32_LIBRARY ws2_32)
target_link_libraries(Hello ${WS2_32_LIBRARY} ${Boost_SYSTEM_LIBRARY})
