Load Linux-side dependencies

cd /media/sf_SHAREDFOLDER/osxcross/tools
sudo ./get_dependencies.sh

Download the Apple Xcode SDK

1. Boot into OS X
2. [Download Xcode (used 5.1)]
3. [Mount Xcode.dmg (Open With -> DiskImageMounter)]
4. Run: ./tools/gen_sdk_package.sh (from the OSXCross package). This script will generate a packaged SDK for each version of OS X that is contained in the Xcode disk image. You only need to move the one you need in the next step (todo: need to specify if it's going to be 10.8 or 10.9)
5. Copy the packaged SDK (.tar. or *.pkg) on a USB Stick
6. Reboot back into Linux
7. Copy or move the SDK into the tarball/ directory of OSXCross

Build the toolchain

(FIRST TEST PASS: OSX10.9SDK with min version 10.7)

1. From /media/sf_SHAREDFOLDER/osxcross, run OSX_VERSION_MIN=10.7 ./build.sh (It will search 'tarballs' for your SDK and then build in its own directory)

Building GCC

1. sudo apt-get install libmpc-dev libmpfr-dev libgmp-dev
2. ./build_gcc.sh
