[Insight-users] problem with FLTK and ITK link

[Luis Ibanez]

Hi Richard,

                   Welcome to ITK !

This example depends on a library created in

            InsightApplications/Auxiliary/FltkImageViewer


You *MUST* take that directory too when you extract the
RegionGrowingSegmentation application.

Most of the symbols that the linker is not finding are
defined in that Library.


    Regards,


       Luis
