[Insight-users] Linker-Problem with ITK-DICOM-EXAMPLE

[Clemens M. Hentschke]

Hello, 


I just tried to get the DICOM-reader Demo from the ITK-Software-Guide 
(p. 327) to run with Microsoft Visual Studio 7. My ITK-Version is 2.6 
and the code is as follows:



#include "itkImage.h"

#include <iostream>

#include "itkImageFileReader.h"

#include "itkImageFileWriter.h"

#include "itkRescaleIntensityImageFilter.h"

#include "itkGDCMImageIO.h"

#include <itkSmartPointer.h>


int main()

{

  typedef signed short InputPixelType;

  const unsigned int InputDimension = 2;

  typedef itk::Image< InputPixelType, InputDimension > InputImageType;

  

  typedef itk::ImageFileReader< InputImageType > ReaderType;

  ReaderType::Pointer reader = ReaderType::New();

  reader->SetFileName( "test.dcm" );


  typedef itk::GDCMImageIO ImageIOType;

  ImageIOType::Pointer gdcmImageIO = ImageIOType::New();

  reader->SetImageIO( gdcmImageIO );


    try

       {

       reader->Update();

       }

       catch (itk::ExceptionObject & e)

       {

       std::cerr << "exception in file reader " << std::endl;

       std::cerr << e << std::endl;

       return EXIT_FAILURE;

       }

  

       return 0;

}


When I try to build the project there's a linker error:

I'm a new user of ITK and I have no idea why this Linker-error occurs. 
Does anybody else have some suggestions?

Thank you!
