Complete example:

#include <iostream>
#include <boost/utility.hpp>
#include <boost/ptr_container/ptr_vector.hpp>

struct Foo : boost::noncopyable
{
    Foo() { std::cout << "made a Foo\n"; }
    ~Foo() { std::cout << "destroyed a Foo\n"; }
};

int main() {

    boost::ptr_vector<Foo> foos;

    foos.push_back(new Foo());
    foos.push_back(new Foo());

    foos.clear();

}
