make error - --__i is not working in many versions of windows

Replace --__i with __i=__i-1 in two lines in the header file stl_iterator_base_funcs.h . This should make it work .

I'm having the same problem on Linux. The cause is that std::advance in include/meta/parallel/parallel_for.h searches a -- operator implementation for the iterator class in dataset_view (include/meta/learn/dataset_view.h).

So better than editing the standard headers, I would only add those missing operators to the iterator class in dataset_view.h :

iterator& operator--()
{
    --it_;
    return *this;
}

iterator operator--(int)
{
    auto ret = *this;
    --(*this);
    return ret;
}
