C ++ как вставить массив в хэш-набор?

Мне нужно вставить одномерный массив в хэш-набор.

Но при компиляции произошла ошибка.

#include <stdio.h>
#include <stdlib.h>
#include <hash_set.h>
using namespace std;
int hash_comp(const int* state1,const int* state2) {
    int result = 0;

    for (i = 0; i < 16; i++) 
    {
        if (state1[i] != state2[i]) {
            result = -1;
        }

    }
    return result;
}
struct eqArray
{
    bool operator()(const int* a1,const int* a2) const
  {
    return hash_comp(a1,a2) == 0;
  }
};
hash_set<int*,hash<int*>,eqArray> closelist;
int main(int argc, char** argv)
{
   const int sn[16] = {1,2,3,4,5,6,0,8,9,10,11,12,13,14,7,15};
   closelist.insert(sn);
   return 0;
}
