Is there a way to do this?
Beyond identifying and copying just the changed files individually yourself by hand, I've never seen a way in unix to do this. If you know that there were changes only to a particular subdirectory, you could cd into and run make; make install from there. You don't have to run make or make install only from the top level directory. That's one way you can often somewhat limit the number of changed install files and contain the cascading dependency effect. Otherwise, it's a good time to go refill your cup of coffee or maybe poke your head out into the living room and confirm to your family that you still exist. (Expect some surprised looks the first few times you do this though.) :-) Curt. -- Curtis Olson IVLab / HumanFIRST Program FlightGear Project Twin Cities [EMAIL PROTECTED] [EMAIL PROTECTED] Minnesota http://www.menet.umn.edu/~curt http://www.flightgear.org _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
