error:ISO forbids declaration of 'vector' with no type
编译的时候遇到这个问题，大家帮忙看看是怎么回事啊

代码中先定义了一个CWorkerThread类，接着定义一个CThreadPool类，类中定义了两个vector<CWorkerThread*> m_BusyList; vector<CWorkerThread*> m_IdleList;编译的时候就出现了以上的问题

class CWorkerThread
{};

class CThreadPool
{
private:
unsigned int m_InitNum; //Normal thread num;

protected:
CWorkerThread* GetIdleThread(void);
void AppendToIdleList(CWorkerThread* jobthread);
void MoveToBusyList(CWorkerThread* idlethread);
void MoveToIdleList(CWorkerThread* busythread);

public:
CThreadMutex m_BusyMutex;
CThreadMutex m_IdleMutex;
CThreadMutex m_JobMutex;

CCondition m_BusyCond; //m_BusyCond is used to sync busy thread list
CCondition m_IdleCond; //m_IdleCond is used to sync idle thread list
CCondition m_IdleJobCond; //m_JobCond is used to sync job list

vector<CWorkerThread*> m_BusyList; ///////问题出在这两行
vector<CWorkerThread*> m_IdleList; //
vector<CWorkerThread*>::iterator ite;

CThreadPool();
CThreadPool(int initnum);
virtual ~CThreadPool(){}
void SetInitNum(int initnum){m_InitNum = initnum;}
int GetInitNum(void){return m_InitNum;}
void Run(CJob* job);
};


[解决办法]
看着没啥问题。
