Makefile编译应用程序
cc = gccprom = calc
deps = $(shell find ./ -name "*.h")
src = $(shell find ./ -name "*.c")
obj = $(src:%.c=%.o) # 会将src所有的.c字串替换成.o
$(prom): $(obj)
$(cc) -o $(prom) $(obj)
%.o: %.c $(deps) # %.o:%.c,这是一个模式规则,表示所有的.o目标都依赖于与它同名的.c文件(当然还有deps中列出的头文件)
$(cc) -c $< -o $@ # $<代表的是依赖关系表中的第一项(如果想引用的是整个关系表,那么就应该使用$^),具体到这里就是%.c。而$@代表的是当前语句的目标,即%.o
clean:
