調整大小矢量編譯器錯誤

Question

我全局定義：

vector<player> cUser; 

玩家結構是這樣：

struct player 
{ 
char buffer[256]; 
string username; 
string password; 
string version; 
int playerID; 
int X; 
int Y; 
int direction; 
string chats[5]; 
unsigned long robotID[3]; 
int gender; 
int securityLevel; 
float rep; 
int isMember; 
int inBattle; 
int isFollowed; 
int playerLocked; 
string currentMap; 
string lastHavenMap; 
int mapHeight; 
int mapWidth; 
unsigned long money; 
unsigned long points; 
int wins; 
int losses; 
string oldIP; 
string newIP; 
unsigned long lastOnline; 
int layer; 
int rank; 
int kicked; 
void logout(); 
void refresh(); 
//other 
void startLoops(); 
int execLoops; 
//for the robots 
Robots Robot[3]; 
int robotOut; 
int totalRobots; 
void addExp(int, int); 
void subExp(int, int); 
int calcRobotExp(int); 
//battles 
player *enemyBattleUser;//enemy is a player 
npc enemyBattleNpc;//enemy is an npc or boss 
Robots rogueRobot;//enemy is a rogue robot 
string mainBattleUser; 
int battleChoice;//which choice of the battleChoiceType 
int battleChoiceType;//0 attack, 1 team, 2 flee 
int battleSAD;//short for battleSceneAlgorythmsDone 
int battleType;//0-rogue, 1=npc, 2-boss 3-player 
int subHealth(int, int, int); 
void addHealth(int, int, int); 
void battleStart(string, int, int); 
void battleEnd(int); 
void getMove(); 
void userTurn(int&, int&, int&, string&, string&, int&); 
void enemyTurn(int&, int&, int&, string&, string&, int&); 
void extraDamage(int&, string&, string&, int); 
void battleScene(); 
//sockets 
int sockID;//main socket id 
int cSockID;//chat socket id 
void userSockError(); 
//roam 
int rogueBattleCalc(); 
void warp(string, int, int); 
int checkNpcBattle(); 
void sendInitData(); 
void roamWorld(); 
int playerWalk(int); 
//chatting 
void chatLoop(); 
void executeCommand(string); 
int lastMessageSeen[5]; 
string chatName[5]; 
int chatsOpen; 
//threads 
boost::thread mainThread; 
boost::thread chatThread; 
}; 

然後當我嘗試通過以下任何一種來調整它，它給了我一個非常大的錯誤，我相信是告訴我做一個構造函數/析構函數，當我這樣做時，仍然給我同樣的錯誤。

cUser.resize(cUser.size()+1); 

player tempUser; 
//members of tempUser set here 
cUser.push_back(tempUser); 

cUser.erase(index); 

但是，當我以同樣的方式調整這個結構，它工作得很好，它仍然沒有構造函數/析構函數，並且它以同樣的方式定義旁邊cUser。

struct chatbox 
{ 
     //chatbox structure 
     string name; 
     int locked;//0 no, 1 yes 
     int staffOnly;//0 no, 1 yes 
     int mType[5]; 
     int security[5]; 
     string username[5]; 
     string message[5];//the higher the index the newer the message 
     int messagesNo; 
}; 

任何幫助，將不勝感激，謝謝。

一個可能的問題是，你的player類有boost::thread數據成員，而這些都是不可拷貝或轉讓。由於vector::resize()可能需要複製和/或分配，因此編譯失敗。
