## STEP BY STEP INSTALLATION GUIDE: ##

#### Step 1: ####

Get [Cygwin](https://cygwin.com):

32-Bit: https://cygwin.com/setup-x86.exe  
64-Bit: https://cygwin.com/setup-x86_64.exe

Note: *You can compile for 64-bit in a 32-bit environment.*

Click on setup-*.exe and install the following packages:

`git`, `make`, `clang`, `gcc-core`, `gcc-objc`, `gcc-g++`,  
`patch`, `wget`, `libuuid-devel`, `openssl` and `pkg-config`

For LTO support you will also need:

`libllvm-devel`, `libllvm` and `gendef`

The cygLTO.dll import library is missing, create it by hand:

`gendef /bin/cygLTO.dll && dlltool -d cygLTO.def -l /lib/libLTO.dll.a && rm cygLTO.def`

#### Step 2: ####

Open the Cygwin shell:

`C:\Cygwin*\home\<User>\osxcross\tarballs`.

Please see [README](README.md) for more.

#### Step 5: ####
