If the only requirement is that the timestamp file is not exposed, then why don't we introduce a phony target (similar to all, clean, install, etc)? For example we can call the target 'schema'. In our case we need a piece of code to let the user type $ make schema-hello to build hello.dtb and run a schema check. We can do this with something along the lines of # Prevent make from removing *.checked and *.dtb files. .NOTINTERMEDIATE: .%.dtb.checked %.dtb schema-%: .%.dtb.checked; .%.dtb.checked: %.dtb $(info checking the schema of $*) @touch $@ %.dtb: %.dts cp $< $@ regards, Dmitry
