在编译自己的程序时出现下面的错误，想问下怎么解决这个问题：
nvcc -o first first.cu -I/root/NVIDIA_GPU_Computing_SDK/CUDALibraries/common/inc

const unsigned int tid_in_grid=blockDim.x*blockIdx.x+threadIdx.x;
sdata[tid_in_block]=g_idata[tid_in_grid];
__syncthreads();
sdata[tid_in_block]*=(float)bid;
__syncthreads();
g_odata[tid_in_grid]=sdata[tid_in_block];
}
#endif
求大家帮忙解决。
