Question

Suppose I hava a make file like this. I can get normal build through make and get a debug build through make debug. But how to write a target so that I can get both normal build and debug build in one command like make both?

DST := /data/result
debug: CFLAGS += -DDEBUG -g
debug: DST = /some/dir
target: src1.c src2.c
    gcc -bla -bla -o target
    cp target $(DST)
debug: target

My final solution is as follows：

DST := /data/result
debug: CFLAGS += -DDEBUG -g
debug: DST = /some/dir
target: src1.c src2.c
    gcc -bla -bla -o target
    cp target $(DST)
debug: target

both:
    make debug && make clean && make all

Answer 1

NORMAL := /data/result/target
DEBUG := /some/dir/target

$(NORMAL) $(DEBUG): src1.c src2.c
    gcc -bla -bla $(CFLAGS) $^ -o $@

debug: $(DEBUG)
$(DEBUG): CFLAGS += -DDEBUG -g

both: $(NORMAL) $(DEBUG)
