Hi All
I'm trying to use std::vector::push_back() within a Boost.Lambda expression, but am finding it impossible
to bind correctly. Can anyone tell me what I'm doing wrong in this code?
Thanks in advance,
- Rob.
#include <vector>
#include <boost/function.hpp>
#include <boost/lambda/bind.hpp>
void f( )
{
namespace ll = boost::lambda;
using boost::function;
typedef unsigned char Id;
typedef std::vector<Id> Ids;
ll::placeholder1_type x;
Ids ids;
void ( Ids::* push_back )( const Ids::value_type & ) = & Ids::push_back;
function<void(Id)> my_push = ll::bind( push_back, ids, x ); // Line 18
Change ids to ll:var(ids) because the operation 'push_back' needs a mutable object.
(void)my_push;
}
