我有以下问题 .
vector<thread> vThreads;
list<Crob *> lRobs;
list<Crob *>::iterator i;
for(i = lRobs.begin(); i != lRobs.end(); i++)
{
vThreads.push_back(thread((*i)->findPath));
}
我想将方法findPath传递给一个线程，但我只是遇到了很多错误......

我已经尝试传递本地函数，并且没有问题...
Added CRob header
#pragma once
#include "point.hpp"
#include "lab.hpp"
class Crob
{
protected:
Cpoint *pos;
int steps;
Clab *labfind;
string direction;
public:
Crob(Clab *lab);
virtual ~Crob();
virtual void findPath();
void moveTo(int x, int y);
void moveToPrint(int x, int y);
int getSteps(void);
void checkDirection();
};

看起来你正在尝试将非静态方法传递给std :: thread构造函数 . 你不能这样做：非静态方法需要一个对象，因此可以调用它 . 看起来你想要：
