The Eclipse Platform is a modern open source IDE with a built-in debugger GUI and support for several programming languages via plug-ins. Plug-ins can also be used to extend functionality. For many, programmer's notepad and insight will suffice, but others may find it a little out of date. This wiki will guide you through each stage in the setup process, but assumes that you are using Windows, have already installed DevkitPro and are relatively familiar with the concepts of developing Wii Homebrew.

Requirements

Getting Started

  • Extract the eclipse zip to a directory of your choice. I recommend C:\eclipse\ N.B. There is no installer. Create yourself a shortcut to C:\eclipse\eclipse.exe, for convenience.
  • Fire up Eclipse, and if all goes to plan you should be greeted with a box asking you to select a workspace. Pick wherever you like, but for the sake of this guide, we will choose C:\WiiDev\projects\. You should choose to make this the default if you aren't interested in using Eclipse for any other development projects.
  • You are greeted with the Welcome splash screen. There are some tutorials on using Eclipse, but leave them for now. Head to File > New > C++ project (Or C Project, if you prefer, but this guide will reference C++ primarily)
  • In the dialogue box, name your project "HelloWorld" and chose Makefile ¬ Empty Project, then hit Finish.
  • Head to the workbench by clicking the far right arrow icon.
  • You now see the main IDE with Project Explorer, File Editor, Console and others panes.
  • There will be an error and a probably warning in the problems pane. Don't worry about them for now, and open C:\devkitPro\examples\wii\template\source in Windows Explorer. Select the Source folder and makefile, and copy them to clipboard. Return to Eclipse, right click the HelloWorld project in Project Explorer, and paste. The files should now be a part of your project.
  • Head to Projects > Properties, or do the same from the right click menu of helloworld. Click C/C++ Build then choose the behaviour tab. Here, change the value of Build (Incremental Build) to build, then hit OK.
  • With default settings, Eclipse will immediately build your project. The error should no longer be there to pester you.
  • Now, to deal with the warning: Error launching external scanner info generator (gcc -E -P -v -dD C:/WiiDev/projects/.metadata/.plugins/org.eclipse.cdt.make.core/specs.cpp)

The easiest way to fix this is to add C:\devkitPro\devkitPPC\powerpc-gekko\bin; to the start of your PATH environmental variable. You may need to restart, and be careful not to remove part of the existing path.
