Hi!

Can anyone tell me why std::vector < boost::ptr_vector < T > > can not be reserved and resized I can not push_back anything inside vector, due to compile errors?

I am using ptr_vector for storing copyable, but nonassignable objects of type T - in fact objects contains mainly const elements.

Regards.

#include <iostream> #include <vector> #include

class Foo { public: Foo ( int const i, int const & j ) :i_(i), j_(j) {}

Foo ( Foo const & f ) : i_(f.i_), j_(f.j_) {}

private: int const i_; int const & j_; void operator= ( Foo const & f ); };

int main() { using namespace std; using namespace boost;

int k = 10; ptr_vector<Foo> g;

g.push_back ( new Foo(1,k) );

vector d; //d.push_back ( g ); <-- Errors //d.resize(5) //d.reserve(5) }
