Oh, you didn't say this. This is basically the same as my final note: > you'll just have to create explicit rules for all your targets. except instead of you doing it you're relying on your compiler to do it, which is fine. > May be this could have side effects I do not see Make always parses all the makefiles and included makefiles first, before it starts to build anything. During parsing all the prerequisites are gathered together, so this: foo: bar baz ; echo hi is identical to this: foo: ; echo hi foo: bar foo: baz Once the makefiles are parsed there's no way to know which of these was actually seen.
