[ITK Community] [Insight-users] Multiple shared libraries and linking error: itk_nrrdSpaceDimension already defined

[Barbara Post]

Hello,

I'm not sure about what I should change in my project.
I read
https://issues.itk.org/jira/browse/ITK-2861?page=com.atlassian.streams.streams-jira-plugin:activity-stream-issue-tab so this indicates the error is from me, not ITK.

I build a shared library that is a custom Qt4 plugin. I use another set of libraries MYOTHERLIB that provides an itk-tools.dll shared lib with classes dedicating to talking to ITK.

I use MSVC 2010 64 bit compiler, compiled ITK with it.

My error when compiling :
LNK2005: itk_nrrdSpaceDimension already defined in itk-tools.lib(itk-tools.dll)

itk-tools base class, XITKTools, has following ITK includes:

#include <itkImage.h>
#include <itkImageFileWriter.h>
#include <itkImageFileReader.h>
#include <itkMinimumMaximumImageCalculator.h>
#include <itkImageMaskSpatialObject.h>

What else could I check about includes/linkings?

Thanks,

Barbara
