[Insight-users] Re: make problem

[Luis Ibanez]

Hi Burak,

It seems that you forgot to put typedefs for "Pointer"
in the definition of the class: myLevelSetFunction"

We will need the source code of "myLevelSetFunction.h"
to verify this.

Please post that header file to the mailing list if you
are still interested in further advice.

Otherwise, please look at files such as

     itkShapeDetectionLevelSetFunction.h
     itkGeodesicActiveContoursLevelSetFunction.h

for examples on the basic typedefs that you should
have in a class that is managed by SmartPointers.


    Thanks


       Luis
