           You are not using CMake !


If you use CMake for configuring your project, it will take
care of setting up all the appropriate compiler flags required
for building ITK code. Instead of wasting your valuable time
wondering about these annoying details, you could have been
segmenting and registering medical images by now.

Your Visual Studio project currently have Exceptions disabled
(That's what the /GR- flag is). ITK uses exceptions for error
handling, and for taking advantage of RTTI.


Your best options at this point :


  1) Solve the immediate problem by just
     enabling the /GR flag, and wait for
     the next configuration problem to appear.


or


  2) Do the right thing and use CMake
     for configuring your project       :-)



You will find instructions on how to create a CMakeLists.txt
file for your project in the Tutorial sessions:

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

in particular in

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



as well as in the first chapter of the Software Guide
