调试makefile的工具 [英] Tool for debugging makefiles

问题描述

我有一个很大的遗留代码库与非常复杂的makefile，有很多变量。有时我需要改变它们，我发现很难弄清楚为什么这个变化不能像我所期望的那样工作。我想找到的是一个基本上完成make过程的逐步调试的工具，我将在其中给出一个目录，我可以看到不同变量在不同点的值处理。没有一个调试标志，似乎告诉我我想要什么，虽然可能我错过了一些东西。有没有人知道这样做的方式？

解决方案

你是否看过运行 make -n 和 make -np ，biggie make -nd ？

您是否使用最新版本的 gmake ？

调试Makefile他们出色的书使用GNU Make管理项目（ Amazon Link ）。

I have a large legacy codebase with very complicated makefiles, with lots of variables. Sometimes I need to change them, and I find that it's very difficult to figure out why the change isn't working the way I expect. What I'd like to find is a tool that basically does step-through-debugging of the "make" process, where I would give it a directory, and I would be able to see the value of different variables at different points in the process. None of the debug flags to make seem to show me what I want, although it's possible that I'm missing something. Does anyone know of a way to do this?

解决方案

Have you been looking at the output from running make -n and make -np, and the biggie make -nd?

Are you using a fairly recent version of gmake?

Have you looked at the free chapter on Debugging Makefiles available on O'Reilly's site for their excellent book "Managing Projects with GNU Make" (Amazon Link).
