Update GNU jobs to more recent NixOS release

[rgmorris]

Hi,

According to
https://hydra.nixos.org/jobset/gnu/emacs-trunk#tabs-configuration
GNU Emacs jobs are still on NixOS release-14.12.

Please could someone update this to a more recent release, like 18.09, or whatever seems appropriate?

I don't see any reason not to apply the same change to all GNU jobs (all of them seem to be still on 14.12, except coreutils, which seems to be on master).

Thanks!

Does anybody still use the GNU jobsets? If yes we can easily update them, but otherwise it would be better to disable them.

That sounds like a pre-guix thing to me.

I'm a GNU Emacs developer, and I still use and appreciate the hydra Emacs jobs, yes.
A few months ago a GNU findutils developer asked about re-activating the findutils jobs:
http://lists.gnu.org/r/hydra-users/2018-09/msg00003.html

I can't speak to the other components.

They point to the 18.09 channel now. However this means some Nix expressions will need updating, e.g. the Emacs jobset now fails to evaluate with:

error: undefined variable 'gtkLibs' at /nix/store/7a0bxz9265gqi08w8ncnvr8kb4v48flb-source/emacs/release.nix:55:12

Thanks for the speedy response. I've fixed the Emacs jobset, and had a go at some of the other GNU ones.

Thanks! I'll close this issue.
