I added following in main.cpp

include <boost/date_time/posix_time/posix_time.hpp>

include <boost/thread/thread.hpp>

Now the error changed as follows

in function void boost::this_thread::sleep<boost::date_time::subsecond_duration<boost::posix_time::time_duration, 1000000l> >(boost::date_time::subsecond_duration<boost::posix_time::time_duration, 1000000l> const&)': main.cpp:(.text._ZN5boost11this_thread5sleepINS_9date_time18subsecond_durationINS_10posix_time13time_durationELl1000000EEEEEvRKT_[_ZN5boost11this_thread5sleepINS_9date_time18subsecond_durationINS_10posix_time13time_durationELl1000000EEEEEvRKT_]+0x231): undefined reference toboost::detail::get_current_thread_data()'

Compiling on Linux, I get the same error. Using standard library did the trick for me - only thing to change is line 142 in main.cpp to std::this_thread::sleep_for(std::chrono::milliseconds(100000));

No further includes needed.
