gendev-macos

Genesis/MegaDrive Development Environment for Mac OS X

This project is based on mattkubilus's gendev project. Check his wonderful work first, please! https://github.com/kubilus1/gendev

The purpose of my project is to make gendev be able to build and work properly on Mac OSX with minimal changes applied.

Prerequisites

OS and Build tools

Mac OS X Yosemite 10.10.3 with Command Line Tools for XCode 6.4 is the reference build environment for current release. That means it should be built with Apple LLVM 6.1.0 (clang- 602.0.53).

4.9G disk storage space is required for temporary obj files and target files generation.

I have not tested building it with toolchain in MacPorts. So if you have MacPorts installed and got failed in building. I suggest you install a clean OS X in a Virtual Machine and get a copy of XCode command line tool from https://developer.apple.com/downloads/

Wget

Wget is required during the build progress to download several external source packages.

# Download, compile and install wget:
curl -O http://ftp.gnu.org/gnu/wget/wget-1.16.tar.gz
tar -xzf wget-1.16.tar.gz
cd wget-1.16
./configure --with-ssl=openssl
make
sudo make install
cd .. && rm -rf wget*

Build path accessibility

The path /opt/toolchains/gen/ may required to be created manually with root permission. It should be chmoded to make the shell user writable.

sudo mkdir -p /opt/toolchains/gen
sudo chmod -R 777 /opt

Basic Instructions:

git clone http://github.com/SONIC3D/gendev-macos.git
cd gendev-macos
make

How to use the toolchain

Make proper exports for the toolchain before compile any genesis/32x project:

  export GENDEV=/opt/toolchains/gen
  export PATH=$GENDEV/sh-elf/bin:$GENDEV/m68k-elf/bin:$GENDEV/bin:$PATH
