std::transform and boost::bind won't compile

[Enucatl]

Hi, I'm trying to use boost::bind with a simple function to transform a vector, but I can't compile it. Any idea about what I could be doing wrong?

double plus(double factor, double a1, double a2) {
    return a1 + factor * a2;
}          

int main() {
[...]
int n = 10;
std::vector<double> vector(n, 100);
std::vector<double> to_be_added(n, 1000);

std::transform(
            vector.begin(),
            vector.end(),
            to_be_added.begin(),
            vector.begin(),
            boost::bind(&plus, 10, _2, _3));
}

// boost::bind(&plus, 10, _2, _3));
boost::bind( &plus, 10, _1, _2 ) ) ;

I found a way to avoid that function altogether, with the composition of two binds:

boost::bind(
std::plus<double>(),
    boost::bind(
        std::multiplies<double>(), factor_, _2),
_1));

Both solutions work.
