[Insight-users] itkOptMattesMutualImageToImageMetric redefinition error

[Oscar Esteban Sanz-Dranguet]

Hi all,

I'm trying to use the optimized registration methods of itk. I've 
configured CMakeLists.txt of the project with:

SET( ITK_USE_OPTIMIZED_REGISTRATION_METHODS ON)
SET(ITK_USE_REVIEW ON)

Then I've used the example DeformableRegistration8.cxx, changing the 
include:

#include "itkMattesMutualInformationImageToImageMetric.h" -> #include 
"itkOptMattesMutualInformationImageToImageMetric.h"

And it doesn't compile:
> /usr/include/InsightToolkit/BasicFilters/itkBSplineInterpolateImageFunction.h:81: 
> error: redefinition of default argument for 'class TCoordRep'
> /usr/include/InsightToolkit/Review/itkOptBSplineInterpolateImageFunction.h:70: 
> note: original definition appeared here
> In file included from 
> /usr/include/InsightToolkit/BasicFilters/itkBSplineInterpolateImageFunction.h:243,

> from /usr/include/InsightToolkit/Review/itkOptImageToImageMetric.h:34,
> from 
> /usr/include/InsightToolkit/Review/itkOptMattesMutualInformationImageToImageMetric.h:20,

I tried too by deleting all the other includes, but using only the 
include of itkOptMattesMutualInformationImageToImageMetric.h the error's 
still there (plus the new errors of undefined classes).

How should I use the optimized registration methods? (how to configure 
CMake, how to include headers, how to call special members of this 
classes,...)

Thanks in advance,
