I am getting error
ERROR: Program::build() (-1)
Please help me
we can't see what's wrong unless you post your kernel here ("hello_kernels.cl" file). What's the error code?
Here is kernal code:
#pragma OPENCL EXTENSION cl_amd_printf : enable
__constant char hw[] = "Hello World";
__kernel void hello(__global char * out){
size_t tid = get_global_id(0);
out[tid] = hw[tid];
}
your kernels appears to be generating ISA correctly in SKA. You can try to generate buildlog for your kernel using clGetProgramBuildInfo.
