[Nix-dev] instructions for setting up apache + mediawiki is broken

[Bjørn Forsman]

Hi,

Today I tried setting up Apache + MediaWiki, following this guide:

http://nixos.org/wiki/Setting_up_MediaWiki_%26_vhosts

It says I should add this to configuration.nix:

services.postgresql.enable = true;
services.httpd.enable = true;
services.httpd.adminAddr = "admin at example.org";
services.httpd.extraSubservices =
  [ { serviceType = "mediawiki";
      siteName = "My Wiki";
      logo = "http://www.example.org/wiki-logo.png"; # should be 135x135px
      extraConfig =
        ''
          # See http://www.mediawiki.org/wiki/Manual:Configuration_settings
          $wgEmailConfirmToEdit = true;
        '';
    }
  ];

But when I nixos-rebuild it fails pretty bad. The build log is below.

I tried to comment out the httpd config stuff and then I see that
having just "services.prostgresql.enable = true;" fails pretty badly
too.

Best regards,
Bjørn Forsman
