Boost Novelty, Boost :: Bind Nightmare

Question

I have this header (redone from boost asio example):

#ifndef MSGSRV_H_ #define MSGSRV_H_ #include <asio.hpp> #include <boost/array.hpp> #include <boost/bind.hpp> #include <boost/shared_ptr.hpp> #include <boost/system/error_code.hpp> namespace msgSrv { class msgSrv { private: asio::ip::udp::socket *asioSocket; asio::io_service *asioIoService; int listenPort; boost::array<char,1> rcvBuff; asio::ip::udp::endpoint lastRcvdPcktEndp; public: msgSrv(int listenPort); virtual ~msgSrv(); void start(); void pckRcvd( boost::system::error_code &, std::size_t); }; } 

and .cpp:

 #include "msgSrv.h" namespace msgSrv { msgSrv::msgSrv(int listenPort) { // TODO Auto-generated constructor stub this->listenPort = listenPort; try{ asioIoService = new asio::io_service(); asioSocket = new asio::ip::udp::socket(*asioIoService, asio::ip::udp::endpoint(asio::ip::udp::v4(), listenPort)); //new asio::ip::udp::socket_(*asioIoService, udp::endpoint(udp::v4(), listenPort)); }catch(std::exception &e){ std::cerr << "Error initializing ioservice or socket:" << e.what(); } } msgSrv::~msgSrv() { // TODO Auto-generated destructor stub delete asioIoService; delete asioSocket; } void msgSrv::start(){ asioSocket->async_receive_from( asio::buffer(rcvBuff), lastRcvdPcktEndp, boost::bind(&msgSrv::pckRcvd, this, asio::placeholders::error, asio::placeholders::bytes_transferred)); } void msgSrv::pckRcvd( boost::system::error_code &error, std::size_t bytesRcvd){ std::cout << "Rcvd!\n"; } } 

Now he refuses to compile, giving unobvious results:

... and so on. I really don’t know what to do, because I can’t understand what a mistake is!

Answer 1

Due to the large number of templates created, the error messages are quite long, but most of them give what may be a useful context. I made the first mistake and cut the lines too long.

At first, the compiler says where the error is, and what sequence of the template instances led to the fact that the particular template instance led to the creation of the error instance.

 /usr/include/boost/bind.hpp: In member function 'void boost::_bi::list3<A1, A2, A3>::operator()(boost::_bi::type<void>, F&, A&, int) ... /usr/include/boost/bind/bind_template.hpp:61: instantiated from ... /usr/include/asio/detail/bind_handler.hpp:95: instantiated from ... /usr/include/asio/handler_invoke_hook.hpp:62: instantiated from ... /usr/include/asio/detail/handler_invoke_helpers.hpp:39: instantiated from ... /usr/include/asio/detail/bind_handler.hpp:129: instantiated from ... /usr/include/asio/detail/handler_invoke_helpers.hpp:39: instantiated from ... /usr/include/asio/detail/handler_queue.hpp:191: instantiated from ... /usr/include/asio/detail/handler_queue.hpp:171: instantiated from ... /usr/include/asio/detail/handler_alloc_helpers.hpp:137: instantiated from ... /usr/include/asio/detail/handler_queue.hpp:116: instantiated from ... /usr/include/asio/detail/task_io_service.hpp:190: instantiated from ... /usr/include/asio/impl/io_service.ipp:125: instantiated from ... /usr/include/asio/detail/reactive_socket_service.hpp:1376: instantiated from ... /usr/include/asio/datagram_socket_service.hpp:310: instantiated from ... /usr/include/asio/basic_datagram_socket.hpp:756: instantiated from ... 

And here is the line of your code that led to all of this:

 ../src/msgSrv/msgSrv.cpp:37: instantiated from here 

And here is the real mistake:

 /usr/include/boost/bind.hpp:348: error: no match for call to '(boost::_mfi::mf2<void, msgSrv::msgSrv, boost::system::error_code&, unsigned int>) (msgSrv::msgSrv*&, asio::error::basic_errors&, int&)' /usr/include/boost/bind/mem_fn_template.hpp:272: note: candidates are: R boost::_mfi::mf2<R, T, A1, A2>::operator()(T*, A1, A2) const [with R = void, T = msgSrv::msgSrv, A1 = boost::system::error_code&, A2 = unsigned int] /usr/include/boost/bind/mem_fn_template.hpp:291: note: R boost::_mfi::mf2<R, T, A1, A2>::operator()(T&, A1, A2) const [with R = void, T = msgSrv::msgSrv, A1 = boost::system::error_code&, A2 = unsigned int] 

In order to pass arguments, msgSrv::msgSrv*& converted to msgSrv::msgSrv* , but parameter A1 is a link, and boost::system::error_code and asio::error::basic_errors are not referenced.

Edit:

If you read the type requirements for the read handler , you will see that the handler works with the first parameter l - a value of type const error_code . This means that your first parameter must be either const boost::system::error_code& (i.e., a constant reference), or boost::system::error_code , not a reference parameter.

Answer 2

Try STL Error Decryptor to help understand error messages from boilerplate code.

Answer 3

boost:: asio, , :

/usr/include/boost/bind/bind_template.hpp:61: 'typename :: _ -:: result_traits:: :: _ :: bind_t:: () (A1 &, A2 &) [ A1 = asio:: error:: basic_errors , A2 = int , R = void, F = boost:: _ mfi:: mf2, L = boost:: _ bi:: list3bi:: , boost:: arg < 1 > ()(), boost:: arg < 2 > (*)() > ]

, pckRcvd :

 void pckRcvd(asio::error::basic_errors&, int&); 

, ?

Answer 4

- . , ( ):

 boost::bind(&msgSrv::pckRcvd, this, asio::placeholders::error(),asio::placeholders::bytes_transferred()) 

pckRcvd :

 void msgSrv::pckRcvd(boost::system::error_code err, std::size_t siz) 

asioSocket->async_receive_from , :

 asioSocket->async_receive_from( asio::buffer(rcvBuff), lastRcvdPcktEndp, boost::bind(&msgSrv::pckRcvd, this, asio::placeholders::error(),asio::placeholders::bytes_transferred())); 

. :

It seems that the recipient needs a different signature, so I think I need to somehow change pckRcvd ... but ... how?
