[Insight-developers] Compile error with vnl_vector_fixed.h from ITK 2.2.0

[Karthik Krishnan]

To,

You definitely have SIZE multiply defined..

In otherwords you have some line like this in your code defined in the 
global namespace.

#define SIZE 5

Please do not do that.. What's usually done is to prefix global typedefs 
with application names as in #define VTK_SIZE 5

(Actually its a bad idea for vnl do do that since its classes are in the 
global namespace.. but we can't change the VNL code)

Thanks
karthik
