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

[Sergio Andres]

Hi all,

Some days ago I sent a mail asking for help about some conflicts
I got when I compiled my application using ITK 1.6 and VTK 4.2 libs.

I downloaded CVS code of VTK and I got no link errors...

But I get similar link errors when I use vtkDICOMImageReader (CVS code, 
2004-04-26) and ITK 1.6..

The messages are like these:
-------------------------------------------------------------
vtkDICOMParser.lib(DICOMAppHelper.obj) : error LNK2005: "public: virtual

My CMakeLists.txt contains the following lines:

So, if you know how to avoid these errors, please let me know..
Thanks!
