列出GNU make中包含在其定义中包含变量的目标/目标 [英] List goals/targets in GNU make that contain variables in their definition

问题描述

我有一个相当大的makefile，它通过计算变量的名称来动态创建多个目标. (例如foo $(VAR):$(PREREQS)).在扩展这些变量之后，可以说服gnu make吐出一系列目标吗?

I have a fairly large makefile that creates a number of targets on the fly by computing names from variables. (eg foo$(VAR) : $(PREREQS)). Is there any way that gnu make can be convinced to spit out a list of targets after it has expanded these variables?

我希望能够获取任意makefile的目标.我正在尝试为我的外壳编写一个完成函数.

I'd like to be able to get the targets for an aribitrary makefile. I'm trying to write a completion function for my shell.

推荐答案

您可以解析make -pn(即make --print-data-base --dry-run)的输出吗?它打印出所有变量，规则，隐式规则以及将要费力的细节运行哪些命令.

Can you parse the output from make -pn (i.e. make --print-data-base --dry-run)? It prints out all the variables, rules, implicit rules and which commands will be run in laborious detail.
