[Insight-users] GettingStarted-II compilation problem

[Luis Ibanez]

Hi David,

The error messages indicate that the
compiler have not found the declaration
of the class ImageToVTKImage.

Didn't you get a message saying that the
header file "itkImageToVTKImageFilter.h"
wasn't found ?

This is the typical cause for these errors.

In order to compile this example, the
simplest thing to do is to copy the
files

      itkImageToVTKImageFilter.h
      itkImageToVTKImageFilter.txx

in the same directory where your .cxx
file is. These files are available at

   InsightApplications/Auxiliary/vtk

The reason why these files are not
along with the basic source tree of
ITK is that they are a bridge between
ITK and VTK. Putting these files into
ITK will create an artificial dependendy
between ITK and VTK.

Please let us know if you still find
any problems after copying these files
into your directory.


Thanks


    Luis
