error C2065: “blockIdx”: 未声明的标识符？？？求解

wjg_xaut 2009-12-20 07:41:16
编译出现下列错误：
1>e:\visual studio 2008\projects\fft\fft\fft_kernel.cu(18) : error C2065: “blockIdx”: 未声明的标识符
1>e:\visual studio 2008\projects\fft\fft\fft_kernel.cu(18) : error C2228: “.x”的左边必须有类/结构/联合
1> 类型是“'unknown-type'”
1>e:\visual studio 2008\projects\fft\fft\fft_kernel.cu(21) : error C2065: “threadIdx”: 未声明的标识符
1>e:\visual studio 2008\projects\fft\fft\fft_kernel.cu(21) : error C2228: “.x”的左边必须有类/结构/联合
1> 类型是“'unknown-type'”
1>e:\visual studio 2008\projects\fft\fft\fft_kernel.cu(48) : error C3861: “__syncthreads”: 找不到标识符

是什么原因呢？望解答

我把已知道的包含文件都加了，在下面：
#include <stdio.h>
#include "E:\Visual Studio 2008\Projects\FFT\FFT\FFT_head.h"//包含DATANUM和PI
#include <cuda_runtime.h>
#include <cutil.h>
#include <math.h>

指定.cu用nvcc编译，应该是在.cu文件上右键“属性”->“常规”->“项类型”为“CUDA C/C++”吧

error C2065: “blockIdx”: 未声明的标识符？？？如何解决。
CUDA出现 未定义标识符 "threadIdx" ，“blockDim”，“blockIdx”的解决方案
问题描述： 一、确认编译器规则是否为NVcc，检查方法：在解决方案下面找到该文件，然后右击选择属性--常规--右面窗口的“项类型”为CUDA C/C++才可以。 二、如果编译器规则正确，检查文件头文件中是否包含："device_launch_parameters.h"，如果没有包含则要加上，即在文件上面加上 #include &lt;device_launch_parameters...
atomicAdd、threadIdx、blockDim、blockIdx未定义标识符
threadIdx、blockDim、blockIdx未定义标识符 这时直接运行程序看看是否可以运行，能运行就不用管不能运行加头文件 #include “device_launch_parameters.h” atomicAdd未定义标识符，同上，当不能运行时加头文件 #include “sm_20_atomic_functions.h” ...
