[Nix-dev] clang-based stdenv for OSX Yosemite

2014-11-03 Thread Joel 
Daniel Peebles, John Wiegley, Eric Seidel, and myself have been working on a 
clang-based stdenv for OSX for the past few weeks. It is fully functional now 
and you can find it at https://github.com/joelteon/nixpkgs 
. It’s being continuously built on my 
Hydra instance at https://hydra.joelt.io/ . If you 
would like to use our branch you should add hydra.joelt.io to your binary 
caches. To my knowledge this is the only nixpkgs fork that works with Yosemite.

Daniel is also working on a 100% pure stdenv (which involves building Apple’s 
open source libc), but that’s still in the works.

There are a few notable changes besides the obvious change in compiler. We are 
willing to revert these before merging into NixOS upstream, since they’re 
pretty major:

* stdenv.gcc has been renamed to stdenv.cc . In the process 
we fixed a few bugs where packages incorrectly referred to gcc instead of the 
stdenv’s compiler. However, this does result in totally rebuilding the Linux 
stdenv as well, since the generic setup script now expects a $cc variable 
instead of a $gcc variable.
* Instead of using the string “gcc” or “${stdenv.gcc}/bin/gcc”, we now use 
`stdenv.progname` (and `stdenv.prognamexx`).

We had a few motivations for this effort. I’d been considering using clang as 
my stdenv’s main compiler ever since I found out that some of the packages I 
hold dear (such as vim and phantomjs) need to be built with Apple’s ported GCC 
4.2.1. Aside from my philosophical objection to this, Yosemite’s developer 
previews were unable to compile GCC at all (at least for the first 3). I think 
it’s possible to compile GCC on Yosemite GM, but I’m no longer inclined to try 
as this branch now uses Apple’s officially supported compiler.

We’d welcome your input and also your help; there’s still a lot left to do.___

Anyone interested in this project should join ##nix-darwin on
freenode. There's still lots to do!

Thank you so much guys for your stoic effort!
For the nix newbies like me, could you please expand upon
"If you would like to use our branch you should add hydra.joelt.io to your
binary caches."

I have absolutely no clue how to do it :)
Thanks!
Alfredo

You want to set the binary-caches option in nix.conf, e.g.

  binary-caches = http://cache.nixos.org http://hydra.joelt.io

I think nix looks for /etc/nix/nix.conf by default, but this is
configurable via the NIX_CONF_DIR environment variable.

So on a fresh 10.10 with XCode 6.1 the joelteon master branch can't build
things like Python. The error is below, I presume it is because the
downloaded clang depends on libraries that aren't available. Should I just
rebuild the world without binary cache?

Re: [Nix-dev] clang-based stdenv for OSX Yosemite

2014-11-12 Thread Eric Seidel 
Can you update to the latest joelteon/master (3b57c2b) and build Python again? 
Joel's hydra seems to be building Python just fine at the moment, and I've also 
just done it locally without issue.

Thanks!
Eric
