問題

遇到了一個我覺得不會發生問題的問題。

Macintosh-2:huffmanTree yen3$ g++ -o test heap.o test2.o
Undefined symbols:
  "void heap_sort<__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > > >(__gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >, __gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >)", referenced from:
      _main in test2.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
