You first need to install on your system the following software:

• Expat (http://www.libexpat.org/) The Expat XML Parser.
• CMake (http://www.cmake.org) cross-platform, open-source build system.
• GD library (http://www.libgd.org/Main_Page) the GD library, an open source code library for the dynamic creation of images.

The Expat library and the GD library are not required, if you only plan to use the core library in your own programs.

If you do not have CMake installed on your system, you may also try to adopt our plain Makefile for your system.
