[Insight-users] evolutionary optimizer...can't figure it out

[Luis Ibanez]

Hi Dennis,

You simply are missing to link
with the ITKStatistics library.

The NormalVariateGenerator is part
of the ITK Statistics framework.

Please modify your CMakeLists.txt
file and add ITKStatistics in the
TARGET_LINK_LIBRARIES()  command,
along with the other ITK libraries
that you may have right now.


For an example on the use of this
optimizer, you can look at the file
ModelToImageRegistration in


Insight/Examples/Registration/
           ModelToImageRegistration1.cxx



Regards,


    Luis
