[Insight-users] Link error with ITK and VTK ...

[Luis Ibanez]

Hi Sergio,

This conflict arises from the fact that the DICOMParser
library is distributed both with VTK and ITK.

The conflict has been solved in the CVS versions
of VTK and ITK by adding some symbol mangling.


Please use the CVS version of ITK.


Regards,


   Luis
