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
<https://github.com/joelteon/nixpkgs>. It’s being continuously built on my
Hydra instance at https://hydra.joelt.io/ <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 <http://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._______________________________________________
