解决方案
看起来你安装升压的静态版本。
的的boost ::登录:: v2_mt_posix 命名空间在提升动态内置版本中实现（见的此链接）。您的应用程序将尝试对符号从这个命名空间链接，如果你在编译过程中定义BOOST_LOG_DYN_LINK宏。
如果您已经安装Boost.Log的静态建立的版本到/ usr / local，即尝试删除 -DBOOST_LOG_DYN_LINK 从 $ {CMAKE_CXX_FLAGS } 行，重新生成build目录并尝试再次构建。 （旁注：通常你会增加编译器定义的 add_definitions（）命令，看的此链接）
或者重新安装升压的动态版本。
I've tried to make the code as simple as possible and I'm still getting

解决方案
It looks like you installed a static version of boost.
The boost::log::v2_mt_posix namespace is implemented in dynamically built versions of boost (see this link). Your application will attempt to link against symbols from this namespace if you define the BOOST_LOG_DYN_LINK macro during compilation.
If you have the statically built version of Boost.Log installed to /usr/local, try removing the -DBOOST_LOG_DYN_LINK from your ${CMAKE_CXX_FLAGS} line, regenerate your build directory and attempt the build again. (Side note: typically you will add compiler definitions with the add_definitions() command, see this link)
Or, reinstall a dynamic version of boost.
