[settle]

I'm using AMD APP KernelAnalyzer 1.12.1288 with CAL 12.4 and attempting to use vec3 data types in my kernels.

Source Code:

#pragma OPENCL EXTENSION cl_amd_vec3 : enable

__kernel void u3d(uint3 n, uint3 pitch, float h, __global float *u)

{

    uint3 global_offset = (uint3)(get_global_offset(0), get_global_id(1), get_global_id(2));

    uint3 global_id = (uint3)(get_global_id(0), get_global_id(1), get_global_id(2));

    uint l = dot(convert_float3(global_id - global_offset), convert_float3(pitch));

    float3 x = -1 + convert_float3(global_id - global_offset) * h;

    u = dot(sin(M_PI_F * x), 1);

}

If I include the pragma line I get:

OpenCL Compile Error: clBuildProgram failed (CL_BUILD_PROGRAM_FAILURE).

error: can't enable all OpenCL extensions or unrecognized OpenCL extension

  #pragma OPENCL EXTENSION cl_amd_vec3 : enable

                                                                       ^

1 error detected.

If I exclude the pragma line I get:

OpenCL Compile Error: clBuildProgram failed (CL_BUILD_PROGRAM_FAILURE).

calclCompile failedError: Creating kernel u3d failed!

Can anyone tell me what I may be doing wrong or if this is a problem with the KernelAnalyzer?  Thanks!
