All:

I'm using Boost v1.30.2, Windows XP Pro, MS Visual C++ v7.1. I get a compilation error when I try to do something like this:

typedef ublas::vector<double> Vector;

Vector a(3);

Vector c(3);

a[0] = 1.0;

a[1] = 2.0;

a[2] = 3.0;

c = a * 100.0;          // trouble maker

The compilation errors are:

d:\boost\boost-1.30.2\boost\numeric\ublas\vector_expression.hpp(1399): error C2825: 'boost::numeric::ublas::vector_binary_scalar2<E1,E2,F>::const_iterator2_type::iterator_category': cannot form a qualified name

        with

        [

            E1=boost::numeric::ublas::vector<double>,

            E2=boost::numeric::ublas::scalar_const_reference<double>,

            F=boost::numeric::ublas::scalar_multiplies<double,double>

        ]

d:\boost\boost-1.30.2\boost\numeric\ublas\vector_expression.hpp(1399): error C2039: 'iterator_category' : is not a member of 'operator``global namespace'''

d:\boost\boost-1.30.2\boost\numeric\ublas\vector_expression.hpp(1399): error C2146: syntax error : missing ',' before identifier 'iterator_category'

I can perform other matrix and vector operations. I just get errors when I try to do scalar multiplies and divides.

Thanks in advance,
Scott
