Hi Syrine,


              Welcome to ITK !


Please follow first the ITK tutorials:

http://www.itk.org/ITK/help/tutorials.html

In particular:

"Getting Started I"
http://www.itk.org/CourseWare/Training/GettingStartedI-WebPage/index.htm

It will save you a lot of time.

The tutorial guide step-by-step on how to install
and use ITK.

You should also read the ITK Software Guide

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


Regarding your code:

A) You are passing a PNG image as input to a reader.
     You are currently not passing a DICOM image.
   
     for instructions on how to read a DICOM image,
     please look at the Chapter  "Reading and Writing Images"
     in the ITK Software Guide.

B) You CMakeLists.txt file was copies from the Examples
     directory. You may find easier to write your own, by
     following the instructions in the Tutorial.

You should only need something like

CMAKE_MINIMUM_REQUIRED(VERSION 2.4)
IF(COMMAND CMAKE_POLICY)
  CMAKE_POLICY(SET CMP0003 NEW)
ENDIF(COMMAND CMAKE_POLICY)

PROJECT(ImageExamples)
FIND_PACKAGE(ITK REQUIRED)
INCLUDE(${ITK_USE_FILE})


ADD_EXECUTABLE(Image2 Image2.cxx )
TARGET_LINK_LIBRARIES(Image2 ITKIO)


and then run the code from the command line.


C) Whenever you are in doubt about whether
     your messages make it to the mailing list,
     you can check the Archives:
http://www.itk.org/pipermail/insight-users/

     see for example:

    Regards,


           Luis

the c make file is as follow:
CMAKE_MINIMUM_REQUIRED(VERSION 2.4)
IF(COMMAND CMAKE_POLICY)
  CMAKE_POLICY(SET CMP0003 NEW)
ENDIF(COMMAND CMAKE_POLICY)

PROJECT(ImageExamples)
FIND_PACKAGE(ITK REQUIRED)
INCLUDE(${ITK_USE_FILE})
INCLUDE_REGULAR_EXPRESSION("^.*$")

SET(TEMP ${ITK_BINARY_DIR}/Testing/Temporary)

ADD_EXECUTABLE(Image2 Image2.cxx )
TARGET_LINK_LIBRARIES(Image2 ITKIO)

SET(IMAGE_EXAMPLES2 ${CXX_TEST_PATH}/ImageExamples2)
IF( NOT ITK_DISABLE_CXX_TESTING )

IF(BUILD_TESTING)

IF(NOT BORLAND)
  ADD_TEST(Image2Test ${IMAGE_EXAMPLES}
    Image2Test ${ITK_SOURCE_DIR}/Examples/Data/BrainMidSagittalSlice.png
  )
ENDIF(NOT BORLAND)
ENDIF(BUILD_TESTING)
ENDIF( NOT ITK_DISABLE_CXX_TESTING )

and the image2.cxx file is :
#if defined(_MSC_VER)
#pragma warning ( disable : 4786 )
#endif
#include "itkImage.h"
#include "itkImageFileReader.h"
int main( int , char * argv[])
{typedef unsigned char          PixelType;
  const unsigned int             Dimension = 3;

  typedef itk::Image< PixelType, Dimension >   ImageType;
typedef itk::ImageFileReader< ImageType >  ReaderType;
ReaderType::Pointer reader = ReaderType::New();
const char * filename = argv[1];
  reader->SetFileName( filename );
reader->Update();
ImageType::Pointer image = reader->GetOutput();
 return 0;}
