    Error when building OpenCl

    I am new to OpenCL. I come this error when building the kernel source code:

    const char* OpenCLProgram[] = {
    "__kernel void OpenCLfunc( \n",
    " __global float* g_input, \n",
    " __global float* f, \n",
    " __global float* g_output, \n",
    " unsigned int n, \n",
    " __local float *sdata){ \n",
    " unsigned int i = get_global_id(0); \n",
    " f[i] = pow(g_input[i],2); \n",
    " barrier(CLK_LOCAL_MEM_FENCE); \n",
    " unsigned int tid = get_local_id(0); \n",
    " sdata[tid] = (i < n) ? f[i] : 0; \n",
    " barrier(CLK_LOCAL_MEM_FENCE); \n",
    " for(unsigned int s=get_local_size(0)/2; s>0; s>>=1) \n",
    " { \n",
    " if (tid < s) sdata[tid] += sdata[tid + s]; \n",
    " barrier(CLK_LOCAL_MEM_FENCE); \n",
    " } \n",
    " if (tid == 0) g_odata[get_group_id(0)] = sdata[0]; \n",
    "} \n",

    I want to compute the squared value of an array and then use reduction to compute the sum of array. I have the error message:
    Err when building program -11
    Build info err 0
    <program source>:7:39: error: expected '}'
    unsigned int i = get_global_id(0);

    Any suggestion is appreciated. Thank you.

    Declare variable "i" as "size_t" instead of "unsigned int".
