bug#49372: lagrange: illegal instruction

[Christopher Howard]

Hi, I've discovered lagrange is another one of those packages which, if I use a substitute, it gives the error "illegal instruction" when I try to run it. but if I download the source and build it
myself, I have no trouble running it. I'm certain without any research that this is a reproducibility error, due to native instructions not on my processor, but I could do the guix challenge if
somebody could remind me exactly how to tell guix to rebuild that one package from source.

$ guix gc --delete /gnu/store/...-lagrange-VERSION

Take note that lagrange must be removed from all profiles first,
and no file from the "lagrange" package may be opened ...

Greetings,
Maxime.

To test reproducibility, you can also try

# To avoid building the dependencies
$ guix environment lagrange --system=i686-linux --no-grafts
$ (exit environment)
$ guix build lagrange --no-substitutes --system=i686-linux
$ guix challenge lagrange --system=i686-linux

Maybe the issue also exists for the iN86 architecture family ...

Greetings,
Maxime.

I found that there is a spot in the code where it tests if the compiling
computer can support sse4.1, and if so then it enables it. I've added a
configure-flag to disable that. Can you test the new version?

Test it as a substitute?

It seems to have downloaded as a substitute, and I was able to launch the program without getting an error.

I rebuilt from source and challenge now seems to be okay:

christopher@nightshade ~/Repos/guix-working$ guix challenge lagrange

1 store items were analyzed:
  - 1 (100.0%) were identical
  - 0 (0.0%) differed
  - 0 (0.0%) were inconclusive

It sounds like everything's working now so I'm going to close the bug.
