[Insight-users] tiff and jpeg duplicate symbols at link time.

[Luis Ibanez]

Hi Corinne,

This is due to the fact that both ITK and VTK
are supporting the TIFF, JPEG and PNG libraries.

Symbols from the VTK tiff library get in conflict
at link time with symbols from the ITK library.

This was recently solved in ITK...by masking the
common symbols.

My guess is that you don't have a fully updated
ITK version.  You may want to do

             cvs update -dPA

at the top level of your source checkout, and
then rebuild ITK.

Please let us know if you still find any problems,

Thanks


   Luis
