[Insight-users] How to turn on Debug.

[Yuanxin Zhu]

Hello, Everyone:

My program ran into a exception "Could not create IO object for file...".
I'd like to turn on the Debug flag so I could get more information about
the bug. Would any of you give me a hint as to how to turn on the debug?
In addition, would FLTK be required to do so? If so, which version of FLTK
should be used?

Thank you so much in advance.
