I’m trying to serialize a template class with multiple template parameters. In the header file, I declare something like

template <int T1, int T2>

class Node

{

private:

std::array<double,T1> first;

std::array<double,T2> second;

}

BOOST_CLASS_EXPORT_KEY(Node<1,1>)

In a separate file, I would use the BOOST_CLASS_EXPORT_IMPLEMENT macro. However, when I’m using the BOOST_CLASS_EXPORT_KEY with  a class that has more than one template parameter (as in the example above), I get an error message

Error: macro "BOOST_CLASS_EXPORT_KEY" passed 2 arguments, but takes just 1

I’m using gcc 4.7.1 with boost 50

Any ideas, how to solve that problem?
