I wanted to ask if the - src/your_login/step_world_v5_packed_properties.cl is indeed a .cl file. Because from the context it makes sense to be a .cpp file.

define CL_USE_DEPRECATED_OPENCL_1_1_APIS is required to allow support for clEnqueueBarrier.

The line 188-192 in cl.hpp will cause compile error in the OS X. Error message is: 'tr1/functional' file not found in cl.hpp

I replace the cl.hpp with the version from http://www.khronos.org/registry/cl/api/1.1/cl.hpp, and it works with Xcode 5 with OpenCL.framework in OS X 10.9 SDK.

I still can't use command line tools to compile test_opencl.cpp, the link stage will fail. Need to find a way to link OS X SDK OpenCL.framework to the compiler.

Can we work in Windows / Visual Studio/ Cygwin, or do we need to work in Linux? Because the input/output functions in process.cpp do not work in Windows. Thank you
