what difference between %.c , *.c in makefiles. example may have: vpath %.c $(base_dir)platform/$(target) and files += $(wildcard *.c) both include files in directory end .c take account. when use %.c , when *.c ? in other words why can't use vpath *.c $(base_dir)platform/$(target) instead of vpath %.c $(base_dir)platform/$(target) ? thank you. both % , * in gnu make wildcard functions. difference between them % can used part of text substitution function whereas * cannot. if trying make fastest possible makefile, should try , use * wildcard function in preference % substitution function there should no resources used store name of matched item , substitute subsequent function call. if not bothered optimising make system limit, not need worry 1 choose.
