Introduction

This article will cover the how to setup Obective-C and it's Standard Library Foundation. The following git repos will be used in this guide and will be described in more detail as we go:

  • Tools-Make - provides a set of make files that are used to properly configure Foundation
  • KOS - the main package for making Dreamcast Homebrew. We will need to patch your local git clone with pthread support
  • Libs-Base - provides the Foundation library for Objective-C
  • LibFFI - used for NSTimers and NSInvocation support

Important note: If you haven't setup KOS yet, you must follow the Getting Started Guide. You can then come back and continue with this one.
