[Insight-users] Problem with VC.NET 7.1

[Luis Ibanez]

Hi Ender

Why do you have the header guards commented out ?

 > /*
 > #ifndef __itkEnhancingLevelSetFunction_h_
 > #define __itkEnhancingLevelSetFunction_h_
 > */

and still have the (uncommented) #endif at the
end of your .h file ?


You are also including the .cpp file  at the end of the
header

>> 
>> #ifndef ITK_MANUAL_INSTANTIATION
>> #include "EnhancingLevelSetFunction.cpp"
>> #endif
>> 


If that .cpp file contains the implementation of the
templated class... then you better use extension .txx
because otherwise VisualStudio will attempt to compile
this file.


Please fix the guards of the header file, because if
you are including this header from your .cpp file,
then you are running into a recursive (infinite)
inclusion.




    Regards,


       Luis
