[Boost-users] [lamba] boost::lambda::function_adaptor<Func>::apply means what?

12 Mar 2007

      struct sample
{
	int i;
	sample(int i) : i(i) { }
	bool odd() { return i % 2; }
};

template 
std::basic_ostream &operator<<(std::basic_ostream& ostr,  
sample s) { return ostr << s.i; }

std::vector<sample> from;
std::vector<sample> to;

from.push_back(sample(1));
from.push_back(sample(2));
from.push_back(sample(3));

std::for_each(from.begin(), from.end(), if_then(bind(&sample::odd, _1) ==  
false, bind(&std::vector<sample>::push_back, to, _1)));

VC++ 8 displays dozens of error messages with the first one:

error C2665: 'boost::lambda::function_adaptor<Func>::apply' : none of the  
2 overloads could convert all the argument types

Can anyone tell me how I need to change the lambda expression?

Thanks,
Boris
