install g++ on your ubuntu machine. I have used ubuntu 11.10 to develop this application.

if you are on ubuntu

  sudo apt-get install g++

then follow this three steps. Goto your terminal write this

  make clean
  make
  ./output/advent

if the application is running successfully, then the server is running. You now need connect to this server using telnet from another terminal prompt.

  telnet localhost 3333

This will connect to the server as a client. And you can start playing the game. Enjoy !!!

If you need help running this contact me through github :)
