Quick self-reply: My make-audit tool only reports a few errors, but they are very general and apply to all rules. This is probably the best way to compare the tools. Here are the make-audit reports: * Error: Target TARGET : unreported prerequisites: SET : The make recipe for creating TARGET is reading from the prerequisites in SET, but the makefile fails to report them as dependencies. You may want to add SET to the prerequisites of TARGET. * Error: Target TARGET : claimed but unused prerequisites: SET : The make recipe for creating TARGET claims that it depends on SET, but the items in SET were never read. You may want to remove SET from the prerequisites of TARGET. * Error: Target TARGET : unreported target: SET The make recipe for updating TARGET also modifies the files in SET but this is not reported. The easy solution is to use GNU make's grouped targets feature that it added in version 4.3, e.g., TARGET SET &: PREREQUISITES. There are alternative solutions. * Error: Target TARGET : unmodified reported target: SET The make recipe for updating TARGET does not appear to actually write to TARGET. You may need to add a missing command to actually modify TARGET.
