For debugging Quetoo , launch the game in
gdb either at the command line, or through Eclipse. Be sure that you start the game in windowed mode so that you can interact with
gdb when you reach a break-point.
If developing on OS X, open
quetoo.xcworkspace in Xcode, and run the game through Xcode. Xcode's
lldb debugger works wonderfully with Quetoo. OS X will correctly make Xcode the active window when breakpoints are hit, so you can debug the game while running it in fullscreen mode.
