Makefile编译应用程序

cc = gcc prom = 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:       rm -rf $(obj) $(prom)
