[Insight-users] problem linking QT with ITK

Hi Yannick


Please try the following,

Take the symbols that are being reported as duplicate
symbols at link time, and add them to the file


        Insight/Utilities/png/
                  itk_png_mangle.h


Then

      1) recompile ITK.
      2) recompile your application.


The symbols in the itk_png_mangle.h file are mangled to
prevent them from colliding with external PNG libraries.


Please let us know if that works ok for you.


   Thanks


     Luis
