stdenv-darwin build problem

[davidak]

Issue description

i want to build a package on darwin (from git master commit https://github.com/NixOS/nixpkgs/tree/358900674b9ecf85ef4add5fa36aa0eb94f76c36) but get this error:

building path(s) ‘/nix/store/f2cdni6pj5mj7cv59w8hyny8gjn6q8gf-stdenv-darwin’
output ‘/nix/store/f2cdni6pj5mj7cv59w8hyny8gjn6q8gf-stdenv-darwin’ is not allowed to refer to path ‘/nix/store/96kz6yfzhx9v7i591sdp015lscwp1xa8-llvm-3.7.1’

same error on different machines, so not a local problem.

Steps to reproduce

nix-env -iA hello -f ~/code/nixpkgs/

Technical details

• System: OS X 10.10.5 / 10.9.5
• Nix version: nix-env (Nix) 1.11.2
• Nixpkgs version: git master

I'll try to take a look this weekend, but unsure I'll have the time

👍 Thank you, @copumpkin!

We should also fix mysql as it's blocking the channel: http://hydra.nixos.org/build/34620439

[davidak]

@domenkozar here is my latest error #11861 (comment)

[copumpkin]

@davidak @domenkozar I will take a look and see if it's an easy fix. Is there a bug for the actual mariadb brokenness? I couldn't see one

[davidak]

@copumpkin the linked issue is about that problem.

[copumpkin]

@davidak I think mariadb/mysql is good again. Can you give it a quick go to make sure I didn't break something subtle?

[davidak]

@copumpkin it builds now but again this priority conflict:

[copumpkin]

That sounds like a broader multiple-outputs issue that shouldn't be specific to darwin. It looks like the post-install script explicitly copies mysql_config into $lib/bin: https://github.com/NixOS/nixpkgs/blob/master/pkgs/servers/sql/mariadb/default.nix#L112-L115

Not sure what the proper multiple-outputs behavior here is. @vcunat, any ideas?
