[Insight-users] Problem when running wiki example ITK/Examples/IO/ImageFileReader

[Cory Quammen]

When running a slightly modified version of the example at
http://www.itk.org/Wiki/ITK/Examples/IO/ImageFileReader as

./ImageFileReader
/Users/cquammen/dev/packages/ITK/Testing/Data/Input/cthead1.bmp

I get the error:

terminate called after throwing an instance of 'itk::ImageFileReaderException'
  what():  /Users/cquammen/dev/packages/ITK/Modules/IO/Base/include/itkImageFileReader.txx:144:
 Could not create IO object for file
/Users/cquammen/dev/packages/ITK/Testing/Data/Input/cthead1.bmp
  Tried to create one of the following:
  You probably failed to set a file suffix, or
    set the suffix to an unsupported type.



The exact code I am running is:

#include "itkImage.h"
#include "itkImageFileReader.h"

//#include "QuickView.h"

int main(int argc, char *argv[])
{
  if( argc < 2 )
    {
    std::cerr << "Usage: " << std::endl;
    std::cerr << argv[0] << " inputImageFile" << std::endl;
    return EXIT_FAILURE;
    }

  typedef itk::Image< double, 2 >         ImageType;
  typedef itk::ImageFileReader<ImageType> ReaderType;

  ReaderType::Pointer reader = ReaderType::New();
  reader->SetFileName(argv[1]);
  reader->Update();

  //QuickView viewer;
  //viewer.AddImage<ImageType>(reader->GetOutput());
  //viewer.Visualize();

  return EXIT_SUCCESS;
}



I am compiling the example against a recent git repository version of ITK:

I've compiled ITK with the following non-default options:

BUILD_TESTING=OFF
CMAKE_BUILD_TYPE=Debug
ITK_BUILD_ALL_MODULES=ON



I've set the following environment variables:
ITK_AUTOLOAD_PATH="/Users/cquammen/dev/build/ITK-Git-IO-Test/lib/"
DYLD_LIBRARY_PATH="/Users/cquammen/dev/build/ITK-Git-IO-Test/lib/"



ls -1 $ITK_AUTOLOAD_PATH yields

This should be a piece of cake to get to run. What am I missing?

By the way, in a different build of the same ITK source file with
BUILD_TESTING on, ITK tests that read images work fine, so I am
stymied.
