This one IS tested!
#include "boost/lambda/lambda.hpp" #include "boost/lambda/bind.hpp" #include <vector> #include <numeric> #include <iostream>
struct A{ int a; std::string b; };
int a_sum(int i, const A &v){ return i + v.a; }
int main( ) { using namespace boost::lambda; std::vector<A> v; for ( unsigned i=1; i != 6; ++i) { A a = { i, "" }; v.push_back( a ); }
int result = std::accumulate(v.begin(),v.end(),0, _1 + bind(&A::a,_2)); std::cout << result << "\n"; }
What compiler are you using? Doesn't work on VC 2005 or 2008. Overload resolution ambiguity failure on boost::lambda::function_adaptor<Func>::apply
