Getting Started/devkitPPC
If your host platform is Windows then use the Windows Installer/Updater package. Otherwise you may proceed with manual installation.
The first thing that you need to do is create a folder for the devkitPro toolchains. Start by opening a terminal - on OSX use the apple key + space, then type terminal. This command creates the new folder.
mkdir /opt/devkitpro
When we're done the layout for your devkitPro folder should end up like this, each folder links to the appropriate sourceforge package.
devkitpro | +-- devkitPPC +-- examples | | | +-- gamecube | +-- wii +-- libogc
Nothing else should be placed inside these folders unless otherwise instructed by the devkitPro toolchain maintainers. On Windows several of these folders are removed and replaced by the update system.
The first package to install is the devkitARM tarball, obtained from the devkitPPC link shown above. Download the appropriate tarball for your host platform - the files are named as devkitPPC_<revision>-<processor>-<os>.tar.bz2.
