[Insight-users] Failed to allocate memory

[Luis Ibanez]

Hi Sajendra,



The Status of ITK in Windows 64 is the following:


1) ITK builds Nightly on "redwall.kitware", which
    is a Windows 64bits, running Windows Vista and
    Visual Studio 2005.

    The build today has all 1306 unit test passing:
http://www.itk.org/Testing/Sites/redwall.kitware/Win64-Vista-vs8-Release/20080327-0100-Nightly/Test.html

    The compilation produces zero errors and 156 warnings,
    most of them in Third partylibraries:
http://www.itk.org/Testing/Sites/redwall.kitware/Win64-Vista-vs8-Release/20080327-0100-Nightly/BuildWarning.html



2) There are no specific CMake flags to enable.
    Simply select the compiler:

          "Visual Studio 2005 - 64bits"

    when you configure the build for the first
    time. Note the specific "64 bits" at the end.



3) I'm not sure about the option of cross-compiling.
    It may be possible. I know that CMake itself
    supports and facilitates cross-compilation, but
    I know of an effort at the Rensselaer Polytechnic
    Institute for cross-compiling ITK in order to run
    it in a BlueGene supercomputer, and that required
    several changes to CMakeLists.txt files.




To summarize:

     Yes, ITK is working on Windows 64 bits.

     Just configure with CMake and start
     enjoying ITK   :-)



Please let us know if you encounter any problems.


    Thanks


      Luis
