我在Windows 10上使用示例构建websocketpp时遇到问题。

这是我的工作:

我首先打开CMake GUI,并指定“D:/ third-party-software / websocketpp”(这是我将websocketpp克隆到的目录)作为源代码的位置,并将“D:/ third-party-software” / websocketpp / build”作为构建二进制文件的位置。

然后,我按下“配置”按钮,它询问我是否要创建构建文件夹,我要选择该文件夹,然后询问我要用于该项目的生成器,要使用的任何可选工具集(-T的参数),以及要使用的编译器,我分别选择“Visual Studio 15 2017 Win64”,没有可选工具集(空字符串)和“使用默认本机编译器”。

然后设置以下参数:

  • BUILD_EXAMPLES:
  • BOOST_ROOT:“C:/ Program1 / boost / boost_1_67_0”
  • Boost_<LIBRARY-NAME>_LIBRARY_DEBUGBOOST_<LIBRARY-NAME>_LIBRARY_RELEASE:
    “C:/Program1/boost/boost_1_67_0/lib64-msvc-14.1/boost_ -vc141-mt-gd-x64-1_67.lib”和
    “C:/Program1/boost/boost_1_67_0/lib64-msvc-14.1/boost_ -vc141-mt-x64-1_67.lib”,
    分别针对原子库,计时库,date_time库,random库,系统库和线程库
  • Boost_INCLUDE_DIR:“C:/ Program1 / boost / boost_1_67_0 /”
  • Boost_LIBRARY_DIR_DEBUGBoost_LIBRARY_DIR_RELEASE:“C:/Program1/boost/boost_1_67_0/lib64-msvc-14.1”

  • (我保留Boost_DIR未初始化)

    然后我再次按“配置”,它给出了输出

    我按生成(Generate)创建Visual Studio解决方案,然后按Open Project(开放项目)在Visual Studio 2017中打开该解决方案。

    (我不知道在终端中按这些按钮中的每个命令对应什么命令。)

    在Visual Studio中,我右键单击目标INSTALL,然后单击Build,然后执行两次(以消除很多多余的输出)。这是我第二次执行以下输出的结果:
