CUDA Texture Memory Error: Unrecognized Texture_cuda

CUDA cannot recognize texture

Just began to learn cuda texture memory, from the Internet to find learning materials, but the test, the program is prompted error:

Texture<float, cudatexturetype2d, cudareadmodeelementtype> texref;

Output[y*width + x] = tex2d (Texref, TU, TV);

Texture,tex2d not recognized

The first thought was to find the definition of the function, which was defined in the Cuda_texture_types.h file, defined as

Template<class T, int textype = cudatexturetype1d, enum cudatexturereadmode mode = cudareadmodeelementtype> struct _                         _device_builtin_texture_type__ texture:public texturereference {#if!defined (__cudacc_rtc__) __host__ Texture (int
                   Norm = 0, enum Cudatexturefiltermode fmode = Cudafiltermodepoint,
    Enum Cudatextureaddressmode Amode = cudaaddressmodeclamp) {normalized = norm;
    FilterMode = Fmode;
    Addressmode[0] = Amode;
    ADDRESSMODE[1] = Amode;
    ADDRESSMODE[2] = Amode;
    Channeldesc = cudacreatechanneldesc<t> ();
  SRGB = 0;
                   } __host__ Texture (int norm, enum Cudatexturefiltermode Fmode,     Enum Cudatextureaddressmode amode, struct Cudachannelformatdesc desc) {Normalized
    = Norm;
    FilterMode = Fmode;
    Addressmode[0] = Amode;
    ADDRESSMODE[1] = Amode; AddressMODE[2] = Amode;
    CHANNELDESC = desc;
  SRGB = 0; #endif/*!__cudacc_rtc__ */};

, so the header file is included in the project, and the result is still out of the question.

After a variety of search and consultation, online can not find solutions, and finally thank friends to help solve this problem.

Now write down the solution

Should contain cpu_anim.h this header file,

namely #include "cpu_anim.h"

This file I also uploaded to the resources, the need for the basin friends can download

Here's an example of a texture that's been found elsewhere.

#include "cuda_runtime.h" #include "device_launch_parameters.h" #include <stdio.h> #include <stdlib.h> #
Include "Cuda_texture_types.h" #include <math.h> #include "cuda.h" #include "cpu_anim.h"//call texture must be added to this header file

#define SIZE 256 texture<float, cudatexturetype2d, cudareadmodeelementtype> texref; __global__ void Transformkernel (float* output, int width, int height, float theta) {unsigned int x = Blockidx.x*blockdim
	. x + threadidx.x;
	unsigned int y = blockidx.y*blockdim.y + threadidx.y;
	float u = x/(float) width;
	Float v = y/(float) height;
	U-= 0.5f;
	V-= 0.5f;
	Float tu = U*COSF (theta)-V*sin (theta) + 0.5f;
	Float TV = V*COSF (theta) + U*sinf (theta) + 0.5f;
Output[y*width + x] = tex2d (Texref, TU, TV);
	} void Main () {int width = 25;
	Cudachannelformatdesc Channeldesc = cudacreatechanneldesc (0, 0, 0, cudachannelformatkindfloat);
	Cudaarray*cuarray;
	Cudamallocarray (&cuarray, &channeldesc, width, height); Float*h_data = (float*) malloc (width*height*sizeof (float));
