[Insight-users] problem in running the examples

[Luis Ibanez]

Hi Giorgos,


   You are missing to link to the ITKNumerics library.


   That's the library that contains the ITK Optimizers.



Please post to the mailing list the CMakeLists.txt file
that you wrote for the Registration examples.

    If you didn't write any CMakeLists.txt file,
    then...
               That's the problem   :-)


In that case, please refer to this recent email in the
Archives for details on how to do so:

http://public.kitware.com/pipermail/insight-users/2007-October/023866.html



BTW: When you install ITK, the ITK.sln file is not
      supposed to be copied to the installation directory,
      so that's not the reason why you are having linking
      problems.



   Regards,


       Luis
