[Insight-users] How to turn on Debug.

[Luis Ibanez]

Hi Yuanxin,

FLTK *IS NOT* required for printing out debug
information from ITK classes. We will be in
pretty bad shape if that were the case  :-)

ITK doesn *NOT DEPEND* on FLTK for any functionality.
FLTK is *only* used for some of the demo applications
in InsightApplications, and it is otherwise totally
unrelated to ITK.


What you need to do is to notify ITK that you
want that information to be printed out in
the console.

You will find many examples on how to do this
in the directory


    Insight/Testing/Code/Algorithms

it is more or less:


   #include "itkTextOutput.h"


   itk::OutputWindow::SetInstance(
        itk::TextOutput::New().GetPointer() );



After this, all debuggin messages will appear
in your console.


   Regards,


      Luis
