[Insight-users] Simple image program help

[RJ Stevens]

Hi again, I am building a simple program to open an image based off
the example Image2.
I have included all the information this time, namely the program, the
CMakeLists.txt, and the error messages.

I am running SUSE linux 9.2 with Itk version 1.8. 
Thanks for any input.

Simple program based off of image2 example:

#include "itkImage.h"
#include "itkImageFileReader.h"
#include <iostream>

int main(int , char ** argv)
{

//define variables for image def
typedef unsigned char		PixelType;
const unsigned int		Dimension = 2;

//set pixel type and dimension
typedef itk::Image< PixelType, Dimension > ImageType;

//instantiate the image reader class
typedef itk::ImageFileReader< ImageType > ReaderType;

//use reader class to create a reader object
ReaderType::Pointer reader = ReaderType::New();

//give reader oject filename of image to be loaded into memory
const char * filename = argv[1];
reader->SetFileName(filename);

//reader object is a pipeline source object and responds to pipeline
//update requests. Since this pipeline is of length 1, we must send the
//update reqest manually
reader->Update();

//put the image into an image object
ImageType::Pointer image = reader -> GetOutput();


return 0;
}

The CMakeLists.txt file this program that is mostly borrowed from
InsightApplications after my first attempt did not work:

CMAKE_MINIMUM_REQUIRED(VERSION 1.6)
PROJECT(Segment1)
INCLUDE_REGULAR_EXPRESSION("^.*$")

# Tell CMake's FIND_PACKAGE command where to look for our Find<pkg>
# modules.
SET(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${InsightApplications_SOURCE_DIR})

IF(NOT WIN32)
  OPTION(BUILD_SHARED_LIBS "Build Insight-Applications with shared
libraries." OFF)
ENDIF(NOT WIN32)

# Don't build anything unless the version of CMake is high enough.
# The matching ELSE/ENDIF should be the last lines in the file.
IF("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" GREATER 1.5)


FIND_PACKAGE(ITK)
IF(ITK_FOUND)
	INCLUDE(${ITK_USE_FILE})
ELSE(ITK_FOUND)
	MESSAGE(FATAL_ERROR
		"ITK not found. Set ITK_DIR.")
ENDIF(ITK_FOUND)

#added from CMakeLists.txt from InsightApplications

ADD_EXECUTABLE( Segment1 Segment1.cxx)


# If the version of CMake was too old, complain and build nothing.
# These should be the last lines in this file.
ELSE("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" GREATER 1.5)
  MESSAGE(SEND_ERROR
          "This version of CMake is too old to build InsightApplications.  "
          "Please upgrade to CMake 1.6.")
ENDIF("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" GREATER 1.5)
