tinmop doesn't pass the guix challenge #54

gandalf commented 2025年07月26日 20:23:44 +02:00

It's my first day using Guix, as suggested by tinmop's README.md, but I got this error when checking if build is correct. (On Void Linux distro):

Not sure if it interests you:

[gandalf@voidvm ~]$ guix challenge -v tinmop

Hi @gandalf

Not sure if it interests you:

I am definitely interested, thanks! This is the first time I heard about the guix challenge command, though, and I think I am going to ask to some guix expert to help me to try to figure out what's happening.

Thanks for your report and I hope you are going to have fun with this software!

Hi @gandalf !

As far as I can understand from this document, the command guix challenge fails because something in the building phase make it not deterministic.

Bye!

Is there a way to investigate what the cause of this "non-determineness" is?

Hi @gandalf

I think your question was the right one! 😄

I tried to run the command specified in the guix document above as:

guix challenge --diff=diffoscope tinmop

Note that you are going to need xxd installed also, to see a meaningful binary diff.

But I can not figure out what is going on.

I tried to install elfread from package elfutils (that seems to be used by diffoscope), but the guix command still complains about elfread is not available.

To be honest i have no clue, I am keeping this open, maybe some good idea is going to pop up.

Bye!
