Custom suffixes and rules Make uses a special target, named .SUFFIXES to allow you to define your own suffixes. For example, the dependency line: .SUFFIXES: .foo .bar tells make that you will be using these special suffixes to make your own rules. Similar to how make already knows how to make a .o file from a .c file, you can define rules in the following manner: .foo.bar: tr '[A-Z][a-z]' '[N-Z][A-M][n-z][a-m]' < $< > $@ .c.o: $(CC) $(CFLAGS) -c $< The first rule allows you to create a .bar file from a .foo file. (Don't worry about what it does, it basically scrambles the file.) The second rule is the default rule used by make to create a .o file from a .c file. Previous Index
