[Insight-users] Creating an 3D image fails with an exeptional error

[Luis Ibanez]

Hi Pieter,

Your C++ code looks fine and the CMakeList.txt seems to be Ok too.

The problem could be originated by a mix of old and new versions of the
libraries at link time...

Are you running on Windows or Unix  ?

Please correct me if I'm wrong:
When you said that the problem lies near the declaration of the image
with it's pointer, you mean the line:

  ImageType::Pointer myImage = ImageType::New();

Is that right ?

At this level the only library involved is ITKCommon.lib which manages
the Factories for creation of new objects through the New() operator.
I would suspect that for some reason your program is being linked with
an old version of the ITKCommon.lib library.  Are you creating dll's for
ITK libraries ?  

Do you have by any chance, both an ITKCommon.dll and
ITKCommon.lib in the same ITK binary directory ?



  Thanks

     Luis
