[Insight-users] ITK in Paraview Plugin

[Christian Werner]

I am afraid I did. My vtkITKImageBox was build as a shared library, too 
and this was only possible after rebuilding ITK with shared libraries.

Somehow, if you put that

ADD_PARAVIEW_PLUGIN(SampleImageFilter "1.0"
 SERVER_MANAGER_XML SampleImageFilter.xml
 #GUI_RESOURCE_FILES SampleImageFilterGUI.xml
 SERVER_MANAGER_SOURCES vtkITKSampleImageFilter.cxx
)

into your CMakeList, the compiler does not really seem to care about 
which libraries it has to compile against. It makes no difference for 
the compiling and linking process. I do not even have to mention my 
vtkITKImageBox library which is clearly needed by my filter.

So these libraries oviously have to be available "globally" when 
paraview runs. I added the ITK library path to the LD_LIBRARY_PATH, 
which I think is the place where ParaView looks for shared libraries but 
that did not help.

I asked the guys form ParaView too about that. If everything works fine 
and I have the time I could write a paper about my Paraview-ITK Filtering.

Best regards,
Christian
