In order to be able to build the toolchains for Gamecube�E processor (PowerPC 750) you have to have the CygWin Environment installed. This environment gives you a UNiX-like environment on Windows, a GCC compiler and BINUTILS inclusive.

The best and easiest way is to download the setup.exe file from here. Here's a step-by-step walkthrough of how to install the environment.

• Download the setup.exe
  
  
• Make a directory where the installer should be downloaded to
  
  
• The tool will ask what it should do. Choose Download from Internet
  
  
• Push button Next->
  
  
• Browse to the installer directory you created
  
  
• Push button Next->
  
  
• Choose appropriate internet configuration
  (mostly direct connection will do fine)
  
  
• Push button next->
  Choose a mirror close to you
  
  
• Push button next->
  On the next page you can select which packages to download
  Due to the fact that the whole Cygwin package grew quite large you may select default and add the following packages (or just make sure that they are enabled):
  
  dev:
  autconf
  automake
  binutils
  doxygen
  gcc
  gcc-g++
  gettext
  make
  nasm
  patchutils
  
  editors: (not really needed but might come in handy)
  vim
  
  libs:
  gettext
  
  utils:
  bzip2
  pcre
  
  
• Push button next->
  
  
• Sit back and enjoy a lengthy download
  

After the download finished you have the complete CygWin-Installer residing on your harddisk. Now it is time to install the packages you just downloaded:

• Run setup.exe again
  
  
• This time choose Install from Local Directory
  
  
• Choose the installer-directory (it's your source) and hit Next-->
  
  
• Choose a destination-directory (e.g. C:/Cygwin) and hit Next-->
  
  
• The installer starts it's work

Locate the folder Cygnus Solutions in your Startmenu and start CygWin Bash Shell. If a BASH prompt appears the installation was successful. Now you have a UNiX environment within your Windows.

Before being able to build the Cross Compiler, the tools and libraries for the Gamecube�Eyou need the sources for the components. You can grab the source packages here.

You will need the following packages:
(NOTE:These are the locations I got the sources from, in case these link do not work anymore please look @ http://www.gnu.org for another mirror)

1. binutils-2.14.tar.bz2
   
   
2. gcc-3.3.2.tar.bz2
   
   
3. newlib-1.11.0.tar.gz

The source packages above are confirmed to work together with the latest CygWin release, so you might take newer version but don't be surprised if they won't work correctly !
