C++ Boost asio set_选项错误
我试图在redhat中使用参数0.0.0.0 127.0.0.1运行以下程序,但在socket.set_选项(boost::asio::ip::multicast::join_group(multicast_address))处出现“Exception:set_option:Invalid argument”错误 它还尝试在窗口中运行它,并且在vc++中运行良好。我快没主意了。请帮帮我C++ Boost asio set_选项错误,c++,boost-asio,C++,Boost Asio,我试图在redhat中使用参数0.0.0.0 127.0.0.1运行以下程序,但在socket.set_选项(boost::asio::ip::multicast::join_group(multicast_address))处出现“Exception:set_option:Invalid argument”错误 它还尝试在窗口中运行它,并且在vc++中运行良好。我快没主意了。请帮帮我 // // receiver.cpp // ~~~~~~~~~~~~ // // Copyright (c)
