<div>Hi,<span><br></span></div><div><br></div><div>I'm trying to use ITK v4. I have been able to install it successfully (note that the option ITK_USE_SYSTEM_GDCM doesn't work, it produce a link error to gdcmMSFF).</div>
<div>Anyway, I built it with the internal version of GDCM.<br></div><div><br></div><div>Unfortunately, when I try a reader class
such as itkImageFileReader, I got an error regarding the IO factory classes :</div><div>" Could not create IO object for file "C:/test.png"</div><div> Tried to create one of the
following:<br> You probably failed to set a file suffix, or set the suffix to an unsupported type."</div><div><br></div><div>As you can see, the list of IO object is empty. It seems ITK can't find them. I checked in the include dir and several IO files are available such as itkGDCMImageIO<br>
</div><div><br></div><div>Can someone tell me what's wrong ?</div><div><br></div><div>Regarding the CMakeLists, I created and used two variables <br></div><div>- a ITK_INCLUDE_DIR (path to the include dir) to find the include files<br>
</div><div>- a ITK_LIBRARIES list (list of path to the
libs). Since the libs are not the same compared to ITKv3, I'm not sure which libraries to include in this list and in which order (if it matters), thus I listed all of them in alphabetical order.<br><br>I have no warning/error at compilation time.<br>
</div><div><br></div><div>I hope someone will be able to help me.</div><div>Best</div><div>James.</div></div></div></div></div></div><br>_____________________________________<br>
