Env:
$ apt-get install libbison-dev libfl-dev

Usage:

$ mkdir build
$ cd build
$ cmake ..
$ make
$ ls bin
mdns_client  mdns_responder
$ ./bin/mdns_responder -h
Usage: mdns_responder [-v level ] [-r] [-n name] [-t type] [-d domain] [-p port] [-f file] [-b] [-P pidfile] [-x name=val ...]
          -v verbose mode, level is a number from 0 to 2
             0 = no debugging info (default)
             1 = standard debugging info
             2 = intense debugging info
             can be cycled kill -USR1
          -r also bind to port 53 (port 5353 is always bound)
          -n uses 'name' as the service name (required)
          -t uses 'type' as the service type (default is '_afpovertcp._tcp.')
          -d uses 'domain' as the service domain (default is 'local.')
          -p uses 'port' as the port number (default is '548')
          -f reads a service list from 'file'
          -b forces daemon (background) mode
          -P uses 'pidfile' as the PID file
             (default is '/var/run/mDNSResponder.pid')
             only meaningful if -b also specified
          -x stores name=val in TXT record (default is empty).
             MUST be the last command-line argument;
             all subsequent arguments after -x are treated as name=val pairs.
mdns_responder: You must specify a service name to register (-n) or a service file (-f).

$ ./bin/mdns_client  -h
./bin/mdns_client: invalid option -- 'h'
Usage: mdns_client [-v level] [-t type] [-d domain]
          -v verbose mode, level is a number from 0 to 2
             0 = no debugging info (default)
             1 = standard debugging info
             2 = intense debugging info
          -t uses 'type' as the service type (default is '_afpovertcp._tcp')
          -d uses 'domain' as the domain to browse (default is 'local.')

$ ./bin/mdns_responder -t _study._tcp. -d local -n changyy -b
$ ./bin/mdns_client -t _study._tcp.
Hit ^C when you're bored waiting for responses.
*** Found name = 'changyy', type = '_study._tcp.', domain = 'local.'
