When I ported VTK 5.9.1 to VTK 5.6, I encountered such issues maybe you are encountering the same, ensure you've done following :<o:p></o:p></p>
<p style="margin-left:1.0in">o<span style="font-size:7.0pt"> </span>extra definitions must be added in preprocessor settings :

To have the os/rendering system dependent classes created, following macro must be set :
<br>
<i>#define vtkRenderingCore_AUTOINIT 4(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingFreeTypeOpenGL,vtkRenderingOpenGL)</i><br>
<br>
or a reference to a file, containing the previous macro, like this must be added in preprocessor definitions :<br>
<i>vtkRenderingCore_INCLUDE="vtkRenderingCore_AUTOINIT_vtkInteractionStyle_vtkRenderingFreeType_vtkRenderingFreeTypeOpenGL_vtkRenderingOpenGL.h"</i><o:p></o:p></p>

<pre>I'm attempting to port an existing code base from VTK 5.10 to 6.0. This code base has existed and worked happily with VTK 5.x for a few years now, being built with Visual Studio 2008. When I began the port to 6.0, I followed the migration guide found here: <a href="http://www.vtk.org/Wiki/VTK/VTK_6_Migration_Guide" target="_blank">http://www.vtk.org/Wiki/VTK/VTK_6_Migration_Guide</a> and the code builds and links just fine. However, when I run it, I'm getting access violation exceptions (attempts to read/write protected memory) when I try instantiating with New(). Researching further, I see that this problem is mentioned here: <a href="http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Factories_now_require_defines" target="_blank">http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Factories_now_require_defines</a> HOWEVER I'm not getting NULL objects with the New() call, I'm getting exceptions.

<pre>For what it's worth, I'm building VTK with CMAKE and the only options I'm changing from the default configuration are the following:<o:p></o:p></pre>

<pre>- don't build TESTING<o:p></o:p></pre>
