Hi all I'm looking for a feature or technique in GNU make - I'm not sure what it might be called, and it might be achievable only with other commands.
Basically, I want to concatenate a series of targets in the parameters of a rule command. As a f'rinstance: If I have a set of .A files, and a command AtoB which generates .B files, such that AtoB 1.A # creates 1.B AtoB 2.A # creates 2.B and AtoB 1.A 2.A 3.A 4.A # creates 1.B, 2.B, 3.B and 4.B My question is, how can I specify a rule so that *all* of the changed .A files are invoked on the AtoB command line - ie if 1.A, 2.A and 3.A are changed, I want make to invoke AtoB 1.A 2.A 3.A 4.A rather than AtoB 1.A AtoB 2.A AtoB 3.A Thanks for your thoughts.
