The path to libOpenCL.so ($ATISTREAMSDKROOT/lib/x86) must be includedin $LD_LIBRARY_PATH.2. /usr/lib/OpenCL/vendors/ must have libatiocl32.so and/orlibatiocl64.so.3. Generally, the path to the kernel file (Template_Kernel.cl) specified in thehost program is relative to the executable. Unless an absolute path isspecified, the kernel file must be in the same directory as the executable.For all Windows platforms, the __stdcall calling convention is used. Functionnames are undecorated.For Linux, the calling convention is __cdecl.2.3 Calling Conventions 2-5Copyright © 2010 Advanced Micro Devices, Inc. All rights reserved.
