[bug] [reproducibility] installation contains a build log file mkmf.log

[Apteryks]

Installing nokogiri captures a build time mkmf.log file that contains a non-deterministic file name. See the following diffoscope diff across two builds:

Hi, I'd like to help, but I'm not sure I understand. Can you please help me understand what you're asking, why you think it's a problem, what you're hoping to do that you're prevented from doing? I'm unfamiliar with guix, I'm unfamiliar with diffoscope, and you haven't explained enough about your problem to put this into context for me.

This looks like a temporary file name being generated during the build process, likely part of Ruby's MakeMakefile system. Have you investigated whether this is nokogiri-specific or something more general?

This output is generated from MakeMakefile's have_func method. I'd like to suggest you open an issue upstream with Ruby if you feel the presence of temporary file names is a problem. I'm not at all sure this is actually a problem since it's a temporary file mentioned in a log file, but again without more information I can't judge.

[Apteryks]

Hello; the problem is that the log file gets installed, somehow, and is not reproducible (because of the changing temporary names it includes), so it breaks the reproducibility of builds (building the nokogiri package from source twice doesn't result in a bit indentical copy).

I'll check if this was fixed in later version of Ruby (Guix is still on the aging 2.7.4 version), and open a bug otherwise. Thanks for taking a look!

[flavorjones]

OK, to be clear, this log file is not "installed", we don't package it in the .gem file. It's a log file recording what happened during installation. Feel free to delete it if it bothers you?
