I am not able to compile a kernel file (mykernel.cl) usign atom_add.

#pragma OPENCL EXTENSION cl_khr_global_int32_base_atomics : enable
#pragma OPENCL EXTENSION cl_khr_local_int32_base_atomics : enable


__kernel mykernel ()


    __local int * ptr;

    atom_add (ptr, 1);



This doesn't work any reason why ?? Am i missing out on something here !!
