bug#36806: guix package -i guile-emacs takes Build too slow

[Rostislav Svoboda]

Hi, I'm trying to install guile-emacs using:
    guix package -i guile-emacs
It's been running for almost 20 hours, most of the time at the step:
    building /gnu/store/h8n0z0ihpykz076paavfcp4ply3qx6q0-guile-emacs-0.0.0-0.41120e0.drv...
    \ 'build' phase
Is it hanging or not? If not:
- is there a way to show some progress bar?
- 20+ hours isn't it a bit too long anyway?

Thanx

Yes, you can pass “--verbosity=2” to see details.

We have little to no control over build times.  When a package is slow
to be compiled (such as a full bootstrap build of Guile) then it’s going
to take a long time.

I think, though, that Guile Emacs cannot actually be built at all, so
I’m expecting your 20+ hour build to eventually fail.  That’s why Guix
tries to build it locally in the first place instead of downloading a
ready-made binary from our build farm — because the build farm doesn’t
have a binary to offer (because it failed to build it).

This is the view from our build farm:

    https://ci.guix.gnu.org/search?query=guile-emacs+spec%3Aguix-master+system%3Ax86_64-linux

Doesn’t look good.

Hi Ricardo,

> I think, though, that Guile Emacs cannot actually be built at all,

I followed the https://www.emacswiki.org/emacs/GuileEmacsBuild#toc8 saying

```
The Guix package uses a known-good commit for both Guile and Emacs.
You can see which commits are being used by looking at the package
scripts:

$ guix edit guile-emacs
$ guix edit guile-for-guile-emacs
```

And using the `guix edit guile-emacs` I see the 41120e0 is suposed to
be the know-good commit :(

But I see that the d8d9a8d (build Id 909170) should work.
Unfortunately I'm new[*] to guix so I don't really know what to do
about it / how to change it.
Can you do something about it please?

Thanx
