The problem is that V=1 is already too chatty, so people sometimes hide their stuff - as in this case. I have for some time thought about adding some option so we can select between: - less chatty than today - but print the usefull stuff - full debug - print almost everything It is not that this is hard to implment. But I never have made up my mind how to enable this. V=1 - could be the "less chatty" mode V=2 - could be the "full debug mode" But we already use "V=2" to tell what caused a file to be rebuild. This is on the other hand very seldomly used so we could get away with a new way to request this. So we limit V=n to select between different verbosity levels. What do you think? Sam
