Please provide (as Nvidia in OpenCL SDK provides utils lib source) sources of SDKUtil so we can build samples on Visual Studio 2010..
You can bind the OpenCL.dll/.so as any other lib. All you have to do is to modify the cl.h header. I will give you one example.
Change all function declaration to a typedef, e.g.:
typedef cl_int(CL_API_CALL *fn_clGetPlatformIDs)(cl_uint /* num_entries */, cl_platform_id * /* platforms */, cl_uint * /* num_platforms */) CL_API_SUFFIX__VERSION_1_0;
// Note the little 'fn_' in front of clGetPlatformIDs
// Essentially this is a simple search & replace task
Then declare a function variable for each API-Function, e.g.
Finally bind all functions dynamically somewhere in your code, e.g. for Win32-API.
clGetPlatformIDs = GetProcAddress(<HWND>,"clGetPlatformIDs");
// dont forget to do some error checking!
This way all other code should not need any change.
NOTE: Due to abscence of an ICD this doesnt help you with different OpenCL implementations. Currently this have to be done for each different kind of calling convention/name mangling/and so on (worst case for each vendor).
On the other hand: The changes for binding to e.g. the NVidia Implementation are minor (including those needed for a final ICD), this mod enables the use of virtually any C/C++ Compiler and finally gets you rid of the static OpenCL dependency that prevents execution of your program if no OpenCL is found.
