[Insight-users] Re: Building and running examples

[Luis Ibanez]

Hi Xiang,


Please read the tutorials

http://www.itk.org/HTML/Tutorials.htm

in particular the "Getting Started I"

http://www.itk.org/CourseWare/Training/GettingStartedI-WebPage/index.htm


Where you will find details on how to
write and interpret a CMakeLists.txt file.

You should also look at the introductory
chapter of the ITK Software Guide

   http://www.itk.org/ItkSoftwareGuide.pdf

You will also find there instructions on
the content of CMakeLists.txt files


Regarding your questions


1) How to run the examples:

    Simply open a MS-DOS window, or a Cygwin shell,
    go to the directory where the executable of
    the example is, and type:

     ImageRegistration1 fixedImage.png
                        movingImage.png
                        resampledMovingImage.png
                        differenceAfter.png
                        differenceBefore.png


     all in a single command line.

     The images used in this example can be found in
     the directory:

            Insight/Code/Examples/


2) CMake takes care of Library dependencies for you.
    So, when you link to ITKIO, CMake knows that ITKIO
    depends on ITKCommon, and therefore kindly adds
    ITKCommon to your link line. As a consequence, you
    don't always have to list all the basic libraries,
    specially if you are listing the advanced ones.





   Regards,



      Luis
