I am not sure if you got the answer you needed but I had a similar problem. The goal was to write in our logger the specific version of the project. The problem was that while we are making our own makefile, the overall build system is controlled by our configuration management. This means that all the solutions which say "sync to something then do something" don't really work and I didn't want to manually change the version whenever we commit (a sure source for errors). The solution (which is actually hinted in some of the answers above) is this: in our makefile, I do p4 changes -m1 "./...#have" The result for this is Change change_number on date by user@client 'msg' I simply create the message into a string which is printed by the logger (the change number is the important element but the other is also useful to quickly decide if a certain version contains changes you know you made yourself without going to perforce to check). Hope this helps.
