vs2013，这是错误的:

vs2013,it's wrongs:

我的主要代码是:

thread t1(task1, Parameter_, Mtime, tempVB, TimeStep, m_I, FlagParameter, Parameter_Bound, MaxGeneration, gL, C, POPULATION_SIZE, crossver, mutations, strResult);

void task1(M_args Parameter_, double Mtime, double tempVB, double TimeStep, double m_I, int FlagParameter[], M_args_Bound Parameter_Bound[], int MaxGeneration, float gL, float C, const int POPULATION_SIZE, float crossver, float mutations, stringstream &strResult)
{
solveGPU_cpp(Parameter_, Mtime, tempVB, TimeStep, m_I, FlagParameter, Parameter_Bound, MaxGeneration, gL, C, POPULATION_SIZE, crossver, mutations, strResult);
    cout << "task1 says: " << endl;
}

AND resolveGPU_cpp是.cu的接口功能 那怎么了?

AND solveGPU_cpp is a Interface functions of .cu so what's wrong?

推荐答案

最后一个参数是引用，您需要std::ref(strResult).

The last parameter is by reference you need std::ref(strResult).

赞:

thread t1(task1, Parameter_, Mtime, tempVB, TimeStep, m_I, FlagParameter, Parameter_Bound, MaxGeneration, gL, C, POPULATION_SIZE, crossver, mutations,
  std::ref(strResult));    // Pass reference
