[Insight-developers] Itkzlib stuck at version 1.1.4?

[Luis Ibanez]

Good point,



Sean: as Bill pointed out, please note that we have to
       mangle the symbols from the zlib library in order
       to avoid conflicts with other packages (e.g. VTK)
       that also use the zlib library.

       You will find the mangling file at:

         Insight/Utilities/itkzlib/itk_zlib_mangle.h

       inside you will find a list of #defines that
       convert the zlib symbols to "itk_" symbols.

       The same is done in ITK for tiff, png, jpeg...



    Luis
