The blocks coding guide (https://wiki.gnuradio.org/index.php/BlocksCodingGuide) suggests that if a blocking function must be used in the work function, that a boost thread call such as sleep should be used. In my case, I am reading IQ data from a socket using the recvfrom function that I can call as a non-blocking function in a loop containing a sleep function. Is the following sleep function the right one?
boost::this_thread::sleep_for(boost::chrono::milliseconds(10)) When I attempt to use this, I get a run-time error message stating that_ZN5boost6chrono12steady_clkck3nowEv is an undefined symbol. I expect that this is a linker error. I have included boost_system in my list of target_link_libraries. I'm just not sure if this is even the recommended sleep function to call. Is there another preferred method?
