Hi,
I want to define a range for gsl_vector's. I have tried many versions
according to the manual but none is working. Maybe someone here could
help me.
This is what I do, or least what I think is most promising (the full
code can be found in the attachment):
namespace boost {
template<> struct range_iterator< gsl_vector* >
{
typedef gsl_vector_iterator type;
};
template<>
struct range_iterator< const gsl_vector* >
{
typedef const_gsl_vector_iterator type;
};
range_iterator< gsl_vector* >::type begin( gsl_vector* &x )
{
return gsl_vector_iterator( x );
}
range_iterator< const gsl_vector* >::type begin( const gsl_vector* &x )
{
return const_gsl_vector_iterator( x );
}
range_iterator< gsl_vector* >::type end( gsl_vector* &x )
{
return end_iterator( x );
}
range_iterator< const gsl_vector* >::type end( const gsl_vector* &x )
{
return end_iterator( x );
}
} // namespace boost
The iterators for gsl_vector are defined separately in the attachment.
If I now try to use the range via
typedef boost::range_iterator< gsl_vector* > gsl_iter_type;
gsl_iter_type::type i3 = boost::begin( vec );
gsl_iter_type::type i4 = boost::end( vec );
I get the following compile errors:
/home/karsten/boost/boost_1_43_0/boost/mpl/eval_if.hpp: In Instantiation
