My guess is it can't parse the function-returning-reference-to-array
syntax. You can try this instead:
namespace detail
{
template <typename T, std::size_t N> struct c_array
{
typedef T[N] type;
};
}
// Specific for boost::array: simply returns its elems data member.
template <typename T, std::size_t N>
typename detail::c_array<T,N>::type& get_c_array(boost::array<T,N>& arg)
{
return arg.elems;
}
