Hi,
We reference http://processors.wiki.ti.com/index.php/OpenCV to add our own opencl kernel to dsp.Which is successful.
And we checked the source of http://processors.wiki.ti.com/index.php/Processor_Training:_Multimedia to add C66x_IMG_LIB to opencl kernel(such as Canny,Sobel).
But if we add these function to our opencl kernel :
void IMG_sobel_3x3_8 (const unsigned char *restrict in_data, unsigned char *restrict out_data, int rows, int cols);
kernel void maskVector(global const uchar4* src, global uchar4* dst,int rows,int cols )
{
IMG_sobel_3x3_8(src,dst,rows,cols);
}
The kernel will print :
undefined first referenced
symbol in file
--------- ----------------
IMG_sobel_3x3_8 /tmp/opencl45XB7I.obj
error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "/tmp/opencl45XB7I.out" not
built
>> Compilation failure
ERROR: clBuildProgram(-11, Build program failure)
How could we add C66x_IMG_LIB to opencl kernel?
Best Regards
