class - c++ compile error -

i have class double linked lists:

template <typename t> class akeraios {     struct node     {         t data;          node* prev;          node* next;          node(t t, node* p, node* n) : data(t), prev(p), next(n) {}      };      node* head;      node* tail;  public:      akeraios() : head( null ), tail ( null ) {}      template<int n>      akeraios( t (&arr) [n]) : head( null ), tail ( null )  //meta apo : simainei einai initializer list--arxikopoiisi listas     {         for( int i(0); != n; ++i)              push_back(arr[i]);      }      bool empty() const { return ( !head || !tail ); }     operator bool() const { return !empty(); }      void push_back(t);     void push_front(t);     t pop_back();     t pop_front();      ~akeraios()     {         while(head)         {             node* temp(head);             head=head->next;             delete temp;         }     } }; 

and somewhere in main

  int arr[num1len];     int i=1;       akeraios <int> dlist ( arr );//error line!!     for(i=1;i<=num1len;i++){     double digit;     int div=10;     int j;     for(j=1;j<=i;j++)div=div*div;      digit=number1/div;      int dig=(int) digit; 

the error in error line is:

no matching function call `akeraios::akeraios(int[((unsigned int)((int)num1len))])'

candidates are: akeraios::akeraios(const akeraios&)

note akeraios::akeraios() [with t = int]

this code valid , compliant as-is. way can see messing if had compiler extension vlas , attempted call constructor variable-length array, fail. otherwise, legitimate. visual studio accepts without quarrel.
