If you have everthing properly installed but get this error message within eclipse try this advice from https://stackoverflow.com/questions/9407430/launch-failed-binary-not-found-eclipse-for-c-in-windows

Press CTRL+B (Project -> Build All) before running your project.
The message should disappear now.
