Hi Mykola, As always, thank you very much.
I am surprised. I used the following command to install ZeroMQ: sudo apt-get install libzmq3-dev I am using Ubuntu 14.04 LTS 64 Bit OS. Thanks again. -Ravi On Sunday, 26 November 2017 12:01 AM, Mykola Ostrovskyy via zeromq-dev <[email protected]> wrote: Ravi, It looks like you have a very old version of zmq.hpp header. Both of those methods are templates added along with C++11 support [1]. Check if you have them, if not, you can either update the header or use non-template methods: int timeout = 1000; zmq_socket.setsockopt(ZMQ_ RCVTIMEO, &timeout, sizeof(timeout)); unsigned char* byteptr = static_cast<unsigned char*>(msg.data()); [1] https://github.com/zeromq/cppzmq/commit/34c8e4395c94d34a89bbeaaf2b8f9c94a8293c84 Regards, Mykola 2017-11-25 14:24 GMT+02:00 Ravi Joshi via zeromq-dev <[email protected]>: Hi, >I am trying to use a subscriber in C++ in the following way: >zmq_socket.setsockopt(ZMQ_ RCVTIMEO, 1000); > >But the above line is throwing following error: >no matching function for call to ‘zmq::socket_t::setsockopt( int, int)’ > > >I am also trying to receive published byte array using following code: >unsigned char* byteptr = msg.data<unsigned char>(); > >But the above line is throwing following error: >error: expected primary-expression before ‘unsigned’ > >Please check out the following Pastebin link in order to see the complete code >(https://pastebin.com/XEYduhaD ) > >- >Thanks >Ravi >______________________________ _________________ >zeromq-dev mailing list >[email protected] >https://lists.zeromq.org/ mailman/listinfo/zeromq-dev > _______________________________________________ zeromq-dev mailing list [email protected] https://lists.zeromq.org/mailman/listinfo/zeromq-dev _______________________________________________ zeromq-dev mailing list [email protected] https://lists.zeromq.org/mailman/listinfo/zeromq-dev
