Why do vectors not work in ROS?

edit

H everyone, I can compile the following code in Xcode but I cannot do the same when using rosmake. Here is my .h file:

#ifndef __AStartAlgorithm__AStarAlgorithm__
#define __AStartAlgorithm__AStarAlgorithm__

#include <iostream>
#include <vector>

class AStarAlgorithm{

public:

AStarAlgorithm();
void astar();

 void printmap(std::vector < std::vector<int> >map);

 private:

 };
#endif /* defined(__AStartAlgorithm__AStarAlgorithm__) */

Here is my .cpp:

#include "../header/AStarAlgorithm.h"
#include <iostream>
#include <vector>
AStarAlgorithm::AStarAlgorithm(){


}



void AStarAlgorithm::astar(){

   std::vector<std::vector<int> > map  = {{8,8,8,8,8,8,8},{8,0,0,0,0,0,8},{8,0,0,0,0,0,8},{8,0,1,0,0,2,8},{8,0,0,0,0,0,8},{8,0,0,0,0,0,8},{8,8,8,8,8,8,8}};

   // printmap(map);  
}

/*
void AStarAlgorithm::printmap(std::vector < std::vector<int> >map){

    for(int i = 0; i < map.size(); i++){
        for(int j = 0; j < map[i].size(); j++){
            if(map[i][j] <10){
                std::cout << "|"<<map[i][j] << " |";
            }else{
                std::cout << "|"<<map[i][j] << "|";
            }

        }
        std::cout << std::endl;
    }
    std::cout << std::endl;
}
*/

I want to print out the vector with the commented out code but the problem at the moment is just initialising the vector. Here is my error in ROS:

Any help will be much appreciated! Thank you.
