Error in writing opencl kernel

Hi,

you need to add __global to the parameter on the function to indicate it is global memory space. Also, you don't need address(&) of temp in the kernel function because the kernel argument is already a pointer

here is a modified version of the code:

typedef struct {

int count;

} cnt;

-void funcA(cnt * cnt_temp)

+void funcA(__global cnt * cnt_temp)

{

}

__kernel void photon(__global cnt * temp)

{

int gid = get_global_id(0);

-funcA(&temp);

+funcA(temp);

}
