[Insight-users] double to float problem

[Luis Ibanez]

Hi Yasser,

Thanks for letting us know that the changes worked for you.


About your questions:

1. Yes, it is very likely that when you update to ITK 2.4.1
    you will have to change other things in your code.
    Although we try hard to maintain backwards compatibility,
    there are always some changes in the API that have to be
    made. You may want to avoid updating to ITK 2.4.1. if you
    are in a critical period in your project.


2.  CMake 2.2 has a different way of asking for your
     compiler. It does it as a popup window. Please make
     sure that when you run CMake 2.2 you are creating
     a fresh binary directory from scratch, and that you
     provide the correct name of the compiler when CMake
     ask for it.



   Regards,


      Luis
