doubt on OpenCL's C++ feature

Hi all,
As we know, OpenCL 1.2 begin to support some C++ feature, it was public in 2011, but only AMD support the 1.2version now, Nvidia even dislodge OpenCL example from its latest SDK. I
tried to use OpenCL in a simulation program with C++ on a Nvidia card, but it turn to be a futile effort…I don’t konw how to contine now, begging for your help.

Can you give some references? The OpenCL specification makes no mention of C++ kernel support. AMD does have some support for C++ in kernel code, but this is only for their OpenCL implementation and not supported by all vendors.

Or are you just looking for a C++ host API/framework for OpenCL?
