This is being worked on, please maintain your patience. I have successfully done this before but I don't remember what I did, so I will have to recreate a lot of stuff.

You need:

  • a mind so deadset on cross-compiling you won't stop to think
  • the Xcode .dmg for your target OS X version
  • root access to your build system
  • a good processor and a lot of RAM

I used Ubuntu 14.04 "Trusty Tahr" for doing the initial chroot. The process was as follows:

apt-get install dchroot debootstrap

Then edit /etc/schroot/schroot.conf with your favourite text editor, and add this at the end:

[trusty]
description=Ubuntu Trusty
location=/var/chroot
priority=3
users=your_username
groups=sbuild
root-groups=root

Install a base system:

sudo debootstrap --variant=buildd --arch amd64 trusty /var/chroot/ http://mirror.url.com/ubuntu/

where http://mirror.url.com/ubuntu/ can be any of these mirrors.

Now copy your resolv.conf for internet access (required):

sudo cp /etc/resolv.conf /var/chroot/etc/resolv.conf

Finally, chroot into your target:

sudo chroot /var/chroot

You should now have a working chroot, free for you to destroy as you see fit.
