Question

我有一个用Qt（Win32，VS2010）和CUDA编写的项目，我的cu文件包含Qt头文件。当我尝试用新的Qt 5.0构建我的项目时（Qt 4.8.3没问题），我遇到了以下错误：

C:/Qt/Qt5.0.0/5.0.0/msvc2010/include\QtCore/qobject_impl.h(82): error: too many initializer values

C:/Qt/Qt5.0.0/5.0.0/msvc2010/include\QtCore/qobject_impl.h(85): error: too many initializer values

C:/Qt/Qt5.0.0/5.0.0/msvc2010/include\QtCore/qobject_impl.h(89): error: too many initializer values

我创建了一个简单的项目来重现该错误并将其复制。我相信任何使用Qt标头的CUDA的Qt项目都可以重复它。但是，我添加了简单的代码来重现下面的错误。任何人都可以帮助我吗？

kernel.cu文件：

#include <QtCore/QCoreApplication>

#include "device_launch_parameters.h"

#include <stdio.h>

cudaError_t addWithCuda(int *c, const int *a, const int *b, size_t size);

__global__ void addKernel(int *c, const int *a, const int *b)
{
    int i = threadIdx.x;
    c[i] = a[i] + b[i];
}

int main()
{
    const int arraySize = 5;
    const int a[arraySize] = { 1, 2, 3, 4, 5 };
    const int b[arraySize] = { 10, 20, 30, 40, 50 };
    int c[arraySize] = { 0 };

    cudaError_t cudaStatus = addWithCuda(c, a, b, arraySize);
    return 0;
}

// do something with cuda
cudaError_t addWithCuda(int *c, const int *a, const int *b, size_t size)
{
    int *dev_a = 0;
    int *dev_b = 0;
    int *dev_c = 0;
    cudaError_t cudaStatus;
}

如何用cuda建立Qt5项目？
