Miscellaneous shortcuts Although the examples we have shown do not explicitly say so, you can put more than one file in the target section of the dependency rules. If a file appears as a target more than once in a dependency, all of its source files are included as sources for that target. Here is our sample Makefile again: CFLAGS = -Aa -D_HPUX_SOURCE OBJECTS = data.o main.o io.o project1: $(OBJECTS) cc $(OBJECTS) -o project1 data.o main.o: data.h io.o main.o: io.h This Makefile shows main.o appearing in two places. Make knows by looking at all the dependencies that main.o depends on both data.h and io.h. Previous Next Index
