I thought the quiet build lines like CPPCHECK .stamps/cppcheck/util/error_util.c were a bit ugly, so I came up with [1]. With that plus this change: - $(call quiet,CPPCHECK) --template=gcc --error-exitcode=1 --quiet $< + $(call quiet,CPPCHECK,$<) --template=gcc --error-exitcode=1 --quiet $< you get CPPCHECK util/error_util.c BR, Jani.
