[Insight-users] RE: Installing ITK on Mac OS X

[Luis Ibanez]

Hi DZ,


         That's why we make releases   :-)


    ...because we fix bugs in between them...


You are facing a bug that ITK 2.6 had for building in
the Mac and that was fixed by the time we released ITK 3.2.


You may find interesting to look at the CVS logs of vnl_math.cxx:
http://www.itk.org/cgi-bin/viewcvs.cgi/Utilities/vxl/core/vnl/vnl_math.cxx?rev=1.18&root=Insight&view=log

In particular to the following CVS commits:
http://www.itk.org/cgi-bin/viewcvs.cgi/Utilities/vxl/core/vnl/vnl_math.cxx?root=Insight&r1=1.12&r2=1.13
http://www.itk.org/cgi-bin/viewcvs.cgi/Utilities/vxl/core/vnl/vnl_math.cxx?root=Insight&r1=1.13&r2=1.14


These two changes are from August 2006.


ITK 2.6 was released on March 2006.


   Regards,


      Luis
