I globally define:
vector<player> cUser;
The player struct is as so:
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;
};
Then when i try to resize it by using any of the following, it gives me a very big error which I believe is telling me to make a constructor/destructor, which when I do it still gives me the same error.
cUser.resize(cUser.size()+1);
player tempUser;
//members of tempUser set here
cUser.push_back(tempUser);
cUser.erase(index);
But when I resize this struct in the same way, it works fine and it still has no constructor/destructor, and it is defined right next to cUser in the same way.
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;
};
Any help would be appreciated, thank you.

One possible problem is that your
playerclass hasboost::threaddata members, and these are not copyable or assignable. Sincevector::resize()can require copying and/or assignment, the compilation fails.
