我是做php开发的。初学C++两天。请帮帮我 :)
问题解答
回答1：find_package(Boost 1.62.0)应该改成find_package(Boost REQUIRED COMPONENTS system)再加上target_link_libraries(untitled1 ${Boost_LIBRARIES}) 让cmake去搞定Boost。另外，再加上链接Ws2_32.lib库。
if(WIN32) target_link_libraries(untitled wsock32 ws2_32)endif()回答2：
boost库的组件基本都需要链接
target_link_libraries(untitled1, boost_system)回答3：
undefined reference to boost::system::generic_category()`这是说你没有链接boost_system库
undefined reference to _imp__WSACleanup@0’`是说你没有链接Ws2_32.lib库
回答4：@ds2016 评论长度超过限制，这是加上DEBUG后的输出
