Installation instructions for Cygwin

This guide will help you install Theos on your Windows (7, 8, and 8.1) machine via Cygwin.

Please consider using Windows Subsystem for Linux instead if possible. Cygwin works but is quite limited.

Platform	Minimum OS version	Targets supported
Windows	XP	iOS

All the commands shown in the following instructions are meant to be run as the “user” user, not root. Similarly, Theos is also meant to be run as a normal user, not root.

Install the following prerequisites:
- Cygwin
- git (under Devel)
- make (under Devel)
- ca-certificates (under Net)
- openssh (under Net)
- perl (under Perl)
- python (under Python)
Set up the THEOS environment variable:
```
 echo "export THEOS=~/theos" >> ~/.profile
```
For this change to take effect, you must restart your shell. Open a new tab and do echo $THEOS on your shell to check if this is working.

Clone Theos to your device:

 git clone --recursive https://github.com/theos/theos.git $THEOS

Get the toolchain:

On 32 bit:

 git clone git://github.com/coolstar/iOSToolchain4Win.git $THEOS/toolchain/windows/iphone

On 64 bit:

 git clone -b x86_64 git://github.com/coolstar/iOSToolchain4Win.git $THEOS/toolchain/windows/iphone

You can get patched SDKs from our SDKs repo.
