Hi Kai,
I guess there is no Win64 platform in Visual Studio 2008. The current Windows API is called Win32 so as to distinguish from old 16-bit code abundant in DOS/Windows 3.x days. The collection of Win32 APIs Microsoft distributes is usually called Windows platform SDK, which is used to develop applications targeting both Windows client and server OS.  From the perspective of hardware, x86-64 is not truly 64-bit architecture either, it is an extension to 32-bit architecture.
Unless your application use libraries from .NET Framework,  you can build 32-bit code which should runs fine under 64-bit Windows.

Subject: [Vxl-users] Building VXL Win64 binaries possible?


is it possible to build 64bit vxl-libs (especially vnl-libraries) for a Win7 64-bit OS and a 64-bit application? I have googled a lot but found nothing but indicators that it is not possible. VXL version number is 1.14.0. I used CMake 2.8.1 and 2.8.2 to configure a solution file for MS Visual Studio 9 2008 but in MSVC it is not possible to select Win64 as the platform of choice. I sure will take 'no' for an answer if that should indeed be the case. My apologies for this rather straight forward question but neither the vxl-users FAQ nor the FAQs in the VXL book gave me an answer.

Thanks a lot in advance. Best regards,
