[Insight-users] Building ITK 3 on AMD Win64 with VC2005

[Luis Ibanez]

Hi Reinhold,

Thanks for pointing out this problem and for exploring
solutions for it.

We entered this issue as Bug # 4165 in the bug tracker:

http://public.kitware.com/Bug/bug.php?op=show&bugid=4165


and yesterday we committed a fix in both the ITK 3.0 branch
and the main cvs trunk:


ITK 3.0 Branch:
http://www.itk.org/cgi-bin/viewcvs.cgi/Utilities/vxl/core/vnl/vnl_math.h?root=Insight&r1=1.5&r2=1.5.2.1

HEAD:
http://www.itk.org/cgi-bin/viewcvs.cgi/Utilities/vxl/core/vnl/vnl_math.h?root=Insight&r1=1.5&r2=1.6 



The fix consisted in updating the vnl_math.h file from
its most recent version in the CVS repository of VXL.

This happens to be:

            vnl_math.h revision 1.42 (from CVS VXL)


Please update your checkout of ITK and let us know if
you still find any problems.



    Thanks


       Luis
