[Boost-users] problem compiling ublas vector iterator with templates

Hi,

I'm trying to compile the following piece of code with gcc version
4.2.3 (Ubuntu 4.2.3-2ubuntu7)  and I keep getting the error message
listed below. A colleague of mine told me that he can compile it on
MSVC. If I remove the template and set everything as vector<double>
then it compiles without any problem.

Anyone has an idea of what I may be doing wrong?

Thanks,

Alain

namespace UBLAS = boost::numeric::ublas;
//summation of a vector
template <class Tv>
Tv vectorSum(const UBLAS::vector< Tv >& A)
{
        Tv sum = 0;
        for (UBLAS::vector< Tv >::const_iterator it = A.begin(); it!=A.end(); ++it)
                sum += (*it);

        return sum;
}
