如何在Makefile中使用自动变量获取第二个依赖文件? [英] How to get the second dependency file using Automatic Variables in a Makefile?

问题描述

我需要从规则中获取第n个依赖文件，类似于bash中的$ n.我需要这样做是因为我想将各个依赖文件作为构建程序的选项.

I need to get the nth dependency file from a rule, something similar to $n in bash. I need this because I'd like to feed in individual dependency files as options to the build program.

这是一个例子:

dep.o: dep.src config1.cfg config2.cfg
    parse -cfg1 $2 -cfg2 $3 -o $@ $<

有可能吗?

推荐答案

dep.o: dep.src config1.cfg config2.cfg
    @echo the second preq is $(word 2,$^), the third is $(word 3,$^)
