Hi Ron,

How do you “cast "other" to the multi_array type” here? I used

      Array (const Array& other) : boost::multi_array<double,2>( const_cast<const boost::multi_array<double,2>& > other)

      {

      }

And it failed to compile.

Thank for your help,

Yan

Greetings Yan,

I do not recall the context of the problem you describe below, but It appears that the definition:

Array (const Array& other) :

boost::multi_array<double, 2> (other)

{}

is the problem. the above expression will call the templated constructor. I believe that the solution here is to cast "other" to the multi_array type. That should result in the proper constructor call.

HTH,

ron
