This is a cheap way to get 32-bit ARM working. We don’t support it
officially but lots of people have raspberry pis and similar hardware
they want to install the Nix package manager on.

Ran into the cross perl problem. I've seen this mentioned before, but I'm not clear on the best fix.

Use buildPackages for native dependencies
1996af4 
Unfortunately, releaseTools.nixBuild does not separate native and
non-native build inputs. As an alternative, we can just use
buildPackages to get the native version of some packages like:

- pkgconfig
- git
- curl
- utillinux

Hopefully fixed with 1996af4

Gets farther, up to compiling nix itself, but pkg-config still has issues. Tried a few combinations of including pkg-config and various envvars without success.

is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables OPENSSL_CFLAGS
and OPENSSL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

To get pkg-config, see <http://pkg-config.freedesktop.org/>.

It should work now as soon as NixOS/nixpkgs@987d4b9 hits release-18.09.

Compiles. And runs on ARM! Great work!

Anything blocking this (other than handling merge conflicts)?

Let's merge #3765 (also @matthewbauer's work, ignore my name at the top of the PR) and then fixing the conflicts here should be quite easy.

@matthewbauer What would it take to move this to the current flake based builds?

@matthewbauer

Yeah - it's just moving some stuff around. Updated to resolve conflicts.

@edolstra I think this is a very worthwhile change, could you take a look?

This doesn't seem to build the binaryTarball for armv6/7, does it?
Maybe tarball targets should be added as well. Or how would you install nix without the tarball?
It would be nice, if after this PR, I could shut down nix-on-armv7l

i would be very interested in this to get it working on armhf ubuntu touch devices, is there anything i can do to help?

I'm happy to merge this if someone updates the PR.

I'm happy to merge this if someone updates the PR.

only @matthewbauer can do that i think
since i pinged the author might as well just ask, if possible, could we have tarball targets as well?

Note that github actions run checks.${system} so we'll need to wire that up to really get it to build cross jobs

As our cross-compiling story is quite good these days, and we have a few Nix contributors that know it inside-out, it's reasonable to support ARMv6/7 and see if we are able to maintain it.

Looking at the diff there's little to be maintained inside Nix repo anyway.

Sweet, what is the easiest way to track those cross-compile jobs on Hydra and where would I fetch the binary tarball from?

@domenkozar

https://hydra.nixos.org/job/nix/master/binaryTarballCross.x86_64-linux.armv6l-linux & https://hydra.nixos.org/job/nix/master/binaryTarballCross.x86_64-linux.armv7l-linux

Click on a job and there's a download link for the tarball.
