Could you kindly tell me why the following code does not compile? I guess it
is an allocator issue, but how do I go further?

#include <boost/multi_array.hpp>
#include <iostream>
using namespace std;

int
main () {
   class test{
    int x;
    int y;
  };
  typedef boost::multi_array<test, 3> array_type;
  typedef array_type::index index;
  array_type A(boost::extents[3][4][2]);
  array_type::extent_gen extents;

  return 0;
}

compile errors:
multiArray.cpp:11: error: template argument for ‘template<class _Alloc>
class std::allocator’ uses local type ‘main()::test’
multiArray.cpp:11: error:   trying to instantiate ‘template<class _Alloc>
class std::allocator’
multiArray.cpp:11: error: template argument 3 is invalid
multiArray.cpp:11: error: invalid type in declaration before ‘;’ token
multiArray.cpp:12: error: expected initializer before ‘index’
multiArray.cpp:13: error: cannot convert
‘boost::detail::multi_array::extent_gen<3ul>’ to ‘array_type’ in
initialization
multiArray.cpp:14: error: expected initializer before ‘extents’
