Re: [Boost-Users] boost::shared_ptr confusion...

From: "someuserat" [...]

However, when I try to use the boost::shared_ptr library like so...

typedef boost::shared_ptr<Widget> WidgetPtr;

vector<WidgetPtr> col;

This statement causes gcc to bark with all manner of errors...

vector<WidgetPtr>::const_iterator i = find_if(col.begin(),col.end(),mem_fun(&Widget::IsPrimary));

Change std::mem_fun (it doesn't recognize smart pointers) to boost::mem_fn.
