That is a very broad question ! I suppose you want the shortest distance on the road network ;)
If you want just the distance, there are several webs tools: http://maps.cloudmade.com/ http://openrouteservice.org/ http://www.yournavigation.org/ Plus others I don't have in mind right now. If you want to compute it on your own, then first you need to extract the data from the .osm files into something suited for routing. I did a small tool that you might use http://github.com/Tristramg/osm4routing Then you need to look at shortest path algorithms. If performance is not a real issue (a few seconds at most), then you can go for a plain dijkstra. Otherwise you'll have to look at some more efficient approaches.
