How to use std::bind
bind, compiler-errors
Solution
Your code compiles fine as long as `-std=c++11` switch is passed to `gcc`, and with the November CTP compiler release of Visual Studio 2013.
Here's a sample command line compilation for your code:
g++-4.8 -std=c++11 -O2 -Wall -pedantic main.cpp

Problem
I'm trying to implement the std::bind in an easy example: ``` #include <functional> #include <iostream> using namespace std; using namespace std::placeholders; int multiply(int a, int b) { return a * b; } int main() { auto f = bind(multiply, 5, _1); for (int i = 0; i < 10; i++) { cout << "5 * " << i << " = " << f(i) << endl; } return 0; } ``` however, when I compile this is what I get: ``` test.cpp:5: error: ‘placeholders’ is not a namespace-name test.cpp:5: error: expected namespace-name before ‘;’ token test.cpp: In function ‘int main()’: test.cpp:14: error: ISO C++ forbids declaration of ‘f’ with no type test.cpp:14: error: ‘_1’ was not declared in this scope test.cpp:14: error: ‘bind’ was not declared in this scope test.cpp:17: error: ‘f’ cannot be used as a function ``` awkward when a given example returns compilation errors o.O thank you in advance for your help
