[Insight-users] Failed to allocate memory

[Nithiananthan, Sajendra]

Hi Luis and others,

What is the current status of ITK on 64bit windows? I found this post from a
year ago indicating (at the time) that there might still be problems:
http://public.kitware.com/pipermail/insight-users/2007-February/021058.html

Also, is there any CMake flags that need to be enabled to compile ITK for 64
bits or is it sufficient to just compile it on a 64 bit machine? I assume
there is no way to cross-compile it from 32bit Windows for a 64 bit machine?

Thank you
Sajendra
