Hello there,
I have rules
a.h a.o a:
command
a.h:
a.o: b.h
a: b.o b.h
Since in my case the command creates all target files at one invocation, I would like
to specify something like this in addition:
a.h: b.o b.h
a.o: b.o
which actually amounts to
a.h a.o a: b.o b.h
But I need the two last directives to behave unusually. I need that 'make' checks for
existence of dependency files (and possibly invokes some other commands that create
them) but does not invoke command on account of any of those dependencies to create
targets.
For example, I need that a.o is recreated because of newer b.h nad not because of
newer b.o, but if it gets recreated (because it does not exist or b.h is newer) 'make'
should assure that b.o is present.
I know it is strange but ... maybe somebody knows some trick.
