## Build instructions for Xcode 10.1

**NB** These are used for OS X 10.6/10.7 build, after the [Building using Xcode][xcode] instructions.

### Download libraries

Download [**libiconv-1.15**](http://www.gnu.org/software/libiconv/#downloading) and unpack to ***BuildPath*/Libraries/macold/libiconv-1.15**

### Clone source code and prepare libraries

Go to ***BuildPath*** and run
