[Insight-users] conencted componentimage filter build errror

[Luis Ibanez]

   Hi Ilker,

   The error message from your linker
   is telling you what the problem is:

  "external symbol _main referenced in function _mainCRTStartup"



   You don't have a "main()" function in your code.



   The reason is that you took code from a Test, where we don't
   use "main()" because the "main()" function is in the test
   driver that collects a groups of tests.


   The solution to your problem is to replace the function
   name:


          ConfidenceConenctedImageFilterTest()


   in the file ConfidenceConenctedImageFilterTest.cxx with


                         main()





   You may find useful to read an introductory book
   to C++ before you continue your journey with ITK.




    Regards,



       Luis
