This document contains all the instructions to create a fully working toolchain targeting the Sega Dreamcast system under Berkeley Software Distribution (BSD).

This document was written when using FreeBSD (13.2) but it should be applicable on all BSD systems like NetBSD and OpenBSD.

Introduction

On FreeBSD system, the package manager is the pkg tool.

If you never used the pkg tool before, you will be asked to install it. Please do this before continuing reading the document.

All the operations in this document should be executed with the root user. If you don't want to use with the root user, another option is to escalate your account privileges using the sudo command, which you will need to install:

pkg install sudo

If that is the case, you will need to add the sudo command before all the commands specified below.

Prerequisites

Before doing anything, you will have to install some prerequisites in order to build the whole toolchain.

Installation of required packages

The packages below need to be installed:

pkg install gcc gmake binutils texinfo bash libjpeg-turbo png libelf git subversion python3

On BSD systems, the make command is NOT the same as the GNU Make tool; instead GNU Make is invoked using gmake; you must use gmake instead of make on BSD systems.

Additionally, by default the sh shell is used on BSD, while KallistiOS scripts require the use of bash.

Preparing the environment installation

Enter the following to prepare KallistiOS and the toolchains:

mkdir -p /opt/toolchains/dc/
cd /opt/toolchains/dc/
git clone git://git.code.sf.net/p/cadcdev/kallistios kos
git clone git://git.code.sf.net/p/cadcdev/kos-ports

Compilation

The dc-chain system may be customized by setting up a [Makefile.cfg] file in the root of the dc-chain directory tree. If this is desired, read the main README for more information on setting up custom options for the toolchain; however, in most circumstances, the stable defaults already present in Makefile.dreamcast.cfg will be fine.

Building the toolchain

To build the toolchain, do the following:

Run bash, if not already done: bash
Navigate to the dc-chain directory by entering: cd /opt/toolchains/dc/kos/utils/dc-chain/
(Optional) Copy and alter the Makefile.cfg file options to your liking.
Enter the following to start downloading and building toolchain: gmake

Now it's time to have a coffee as this process can be long: several minutes to hours will be needed to build the full toolchain, depending on your system.

Removing all useless files

After everything is done, you can cleanup all temporary files by entering:

gmake distclean

Next steps

After following this guide, the toolchains should be ready.

Now it's time to compile KallistiOS.

You may consult the README file from KallistiOS now.
