我新建了一个VC项目，里面加入了两个.cu文件，一个是xxx.cu,另一个是xxx_kernel.cu
我定义了xxx.cu用CUDA3.0的rule来编译，在xxx.cu里面定义一个类如下
///////////////////////
xxx.cu文件
///////////////////////
#pragma once
#include <cutil.h>
#include “data_rebuild_kernel.cu”
using namespace std;
template
class CDataRebuilder
{
public:
CDataRebuilder()
{
};
~CDataRebuilder()
{};
void Init(_Ty *p)
{
//.........
};
void Free()
{
}
private:
…
};
在xxx_kernel.cu里面定义一个__global__函数如下
#pragma once
template
global void gppmAddvvT(_Ty *pVectorA, _Ty *pVectorB, _Ty *pVectorC, int iVectrDim)
{
int iTid = blockIdx.x * blockDim.x + threadIdx.x;
if(iTid < iVectrDim)
{
pVectorC[iTid] = pVectorA[iTid] + pVectorB[iTid];
}
}
然后编译，出错，输出信息如下
