The code seems fine except what are you using as an input argument? It does not link correctly on my machine, so I have not been able to test it yet.<div><br></div><div>Caleb</div><div><br><br><div class="gmail_quote">On Tue, May 18, 2010 at 6:35 PM, Qian Cheng <span dir="ltr"><<a href="mailto:qianc@ee.ethz.ch">qianc@ee.ethz.ch</a>></span> wrote:<br>

Hi Caleb,<br>
The code is here, very simple:<br>
/*****************************************/<br>
#include "itkImage.h"<br>
#include "itkImageFileReader.h"<br>
#include "itkImageToVTKImageFilter.h"<br>
<br>
#include "vtkImageViewer.h"<br>
#include "vtkRenderWindowInteractor.h"<br>
<br>
int main(int argc, char **argv){<br>
<br>
typedef itk::Image<unsigned short, 2> ImageType;<br>
typedef itk::ImageFileReader<ImageType> ReaderType;<br>
typedef itk::ImageToVTKImageFilter<ImageType> FilterType;<br>
<br>
ReaderType::Pointer reader = ReaderType::New();<br>
FilterType::Pointer connector = FilterType::New();<br>
<br>
reader->SetFileName(argv[1]);<br>
connector->SetInput(reader->GetOutput());<br>
<br>
vtkImageViewer *viewer = vtkImageViewer::New();<br>
<br>
vtkRenderWindowInteractor *renderWindowInteractor =
vtkRenderWindowInteractor::New();<br>
<br>
viewer->SetupInteractor(renderWindowInteractor);<br>
viewer->SetInput(connector->GetOutput());<br>
viewer->Render();<br>
viewer->SetColorWindow(2000);<br>
viewer->SetColorLevel(1000);<br>
renderWindowInteractor->Start();<br>
<br>
return 0;<br>
}<br>

A segmentation fault is caused by your program attempting to access a
protected region of memory. Its possible that is happening in your code
accidentally.<br>

all,<br>
I am compiling the simple example given by<br>
"<a href="http://www.itk.org/CourseWare/Training/GettingStarted-II.pdf" target="_blank">http://www.itk.org/CourseWare/Training/GettingStarted-II.pdf</a>".<br>
It seems working(showing a picture in a window). But whenever I close<br>
the rendered window, "Segmentation fault" shows up in the command line.<br>
Does anybody know what's wrong? I am running ITK+VTK in my lab's<br>
sever("Linux 2.6.18-194.3.1.el5 #1 SMP Sun May 2 04:17:42 EDT 2010<br>
x86_64 x86_64 x86_64 GNU/Linux") without TCL, QT and FLTK wrapped.<br>
I am new to VTK&ITK, I would appreciate if anybody can help out.<br>
Best,<br>
Cheng<br>
