OpenCL: could not find clRetainDevice in dll

Using the AMD C++ binding and SDK (the most recent one) running an OpenCL program that gets a platform, a GPU, then compiles 4 kernels has the above error upon startup. It works fine on my computer, whose GPU only supports up to 1.1, but other computers seem to have the above error. Is this a problem in the compilation (As in, I have to define some macros), in the lack of a driver, the C++ binding, or something else? I don't explicitly call clRetainDevice in my own code—is it part of the binding somewhere?

It happens when you use the C++ bindings header file with OpenCL 1.2 header. For instance, when you run an application compiled with AMD SDK (OpenCL 1.2) on NVIDIA platform (OpenCL 1.1 only).

As fast and dirty work around, you can just edit the AMD SDK cl.h header and undef "CL_VERSION_1_2" preprocessor symbol. If you are not interested to 1.2 features, it should fix your problem.
