Once you have downloaded, you can compile the code by running. You can download CoCo's complete source code from Precompiled binaries for the three major platforms are provided below if you do not have a compiler installed on your computer. A README accompanies the source code repository to tell you how to compile the program. You may download it by cloning the github repository or by downloading a zip file of the source. The entire source for CoCo is available on GitHub free of charge. Its was designed for educational purposes for learning C++, assembly language, and higher level language implementation. This virtual machine was implemented in C++. Since the majority of Objective-C developers are on Mac OS X using Xcode this allows one to develop and maintain a cross-platform project within one IDE.Welcome to CoCo, a virtual machine based on the Python virtual machine. The CDT is intended to be used from within Apple Inc.'s Xcode as a cross-compiler, and Cocotron itself is an Xcode project. The CDT is a collection of well known and popular open source tools, specifically gcc, binutils and MinGW, which are organized and patched to support the Cocotron project. The Cocotron proper is only source code to a runtime, without a compiler and sufficient tools this is relatively useless, so the project also maintains The Cocotron Developer Tools (CDT). In particular the NT based versions, 2000 up to 10. However, most of the work at this time is focused on providing support for Microsoft Windows. The general goal is to provide complete support on any viable platform, the project is intended to be as portable as possible. In particular, source code level compatibility with recent versions of Apple's frameworks. The purpose of the project is to provide an easy to use cross-platform solution for Objective-C development. This includes the AppKit, Foundation, Objective-C runtime and support APIs such as CoreGraphics and CoreFoundation.

The Cocotron is an open source project which aims to implement a cross-platform Objective-C API similar to that described by Apple Inc.'s Cocoa documentation. You need to install cross-compilers and cross-compile the frameworks using Xcode on Mac OS X. Cocotron is a developer SDK which implements a usable amount AppKit and Foundation for Windows and Foundation for Linux/BSD in Objective-C.
