[vtkusers] VTK 6.0 with Visual Studio

Tue Jul 23 11:30:43 EDT 2013

Thanks for the suggestion.  That's the route I was going to go next (start small, get that working first).  I'll let you know how it goes.

1) Can you provide a small, compilable example that fails?
2) You could try some of the VTK Wiki Examples.
http://www.vtk.org/Wiki/VTK/Examples
3) Find one that uses a class that is failing.
    for example, in google search:

Have you run one of the failing programs in the VS debugger?

Thanks for your suggestion.  This is the definition I tried when I mentioned definition of VTK AUTOINIT.  The links you mentioned, and the ones I did, all discuss this within the context of the New() function returning a NULL value, however, not generating an exception.  As I said, I tried them anyway with no success.

Hello,

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   extra definitions must be added in preprocessor settings :
To have the os/rendering system  dependent classes created,  following macro must be set :
#define vtkRenderingCore_AUTOINIT 4(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingFreeTypeOpenGL,vtkRenderingOpenGL)

or a reference to a file, containing the previous macro, like this must be added in preprocessor definitions :
vtkRenderingCore_INCLUDE="vtkRenderingCore_AUTOINIT_vtkInteractionStyle_vtkRenderingFreeType_vtkRenderingFreeTypeOpenGL_vtkRenderingOpenGL.h"

Hope that helps !

P.S. Links which were useful to me :

Are you able to provide more information on the exact violation

exceptions with a back trace? Access violations can occur when you

call methods on a NULL object, so it could be a case that a object

factory that is NULL is being asked to create classes.

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: http://www.vtk.org/Wiki/VTK/VTK_6_Migration_Guide 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: http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Factories_now_require_defines  HOWEVER I'm not getting NULL objects with the New() call, I'm getting exceptions.  Furthermore, it doesn't happen with ever

 y VTK o

bject; some instantiate and can be used just fine.  Nonetheless, I tried the suggestions at the second link, regarding definition of VTK AUTOINIT, and they proved fruitless.  So I'm currently at a loss...

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:

- build shared libs

- don't build TESTING

- set custom install directory

Thanks for your time; any help would be greatly appreciated...
