Tool for debugging makefiles – Stack Overflow

Posted by jpluimers on 2021/11/23

I’m not good at makefiles, so I needed a tool to help me debug some relatively simple ones.

[Wayback] Tool for debugging makefiles – Stack Overflow came to the rescue.

The suggestion in the first answer was enough: run make -n.

But the other suggestions are great too, so here I quote them (thanks [Wayback] Rob Wells and [Wayback] User Rajish):

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 [Wayback] Debugging Makefiles available on O’Reilly’s site for their excellent book “Managing Projects with GNU Make” ([Wayback] Amazon Link).

I’m sure that [Waybackremake is what you are looking for.

From the homepage:

remake is a patched and modernized version of GNU make utility that adds improved error reporting, the ability to trace execution in a comprehensible way, and a debugger.

It has gdb-like interface and is supported by mdb-mode in (x)emacs which means breakponts, watches etc. And there’s [Wayback] DDD if you don’t like (x)emacs

The free chapter: [Wayback]

Remake documentation: [Wayback] remake – GNU Make with comprehensible tracing, profiling, extended error messages, and a debugger — remake 4.3+dbg-1.4 documentation
