[Boost-users] How to inherit from boost::multi_array

Dear List, I am using boost 1.31.0 on Linux (with gcc 3.3.2) I would like to create a 2D array class, which inherits from boost::multi_array class. However I have problems with the copy constructor of my class Array. Below is the code, which I am trying to run. #include class Array : public boost::multi_array { public: Array (void) : boost::multi_array () {} Array (const int nrow, const int ncol) : boost::multi_array (boost::extents[nrow][ncol]) {} Array (const Array& other) : boost::multi_array (other) {} ~Array (void) {} Array& operator= (const Array& rhs) { if (&rhs != this) { boost::multi_array::operator= (rhs); } return *this; } }; /* class Array */ I guess that I forget to provide some information to my derived class, but I cannot find which one. Is there a way to simply inherits from boost::multi_array? Many thanks in advance, Thomas
