After installation ati stream 2.1 on windows XP I have got:
"Failed to load kernel file : c:\Documents and Settings\Sergey\Documents\ATI
Stream\samples\opencl\bin\debug\x86\BitonicSort_Kernels.cl", when I try to run BitonicSort sample. Other openCL samples have same problem but CAL samples works correctly. Anyone have such problems?
Which location are you running the samples from?
Did you check whether the .cl file is there in the above mentioned location?
