Question

My C++ application compiles and runs as expected in Netbeans. However, Code Assistance does not recognize terms such as cbegin(), cend(), unordered_set, as evinced by red underscores:

Code assistance does recognize end(), however. To no avail, I have tried going to Project -> Properties -> Code Assistance -> C++ Standard -> C++11. What else should I update or configure to let Netbeans Code Assistance recognize these terms?

Answer 1

Make shure you use a Netbeans Version >= 7.2 because the the C++11 support was introduced in this version (see “C/C++”).

If you already have set the C++ standard to C++11 in NB, you can reparse your procject:

1. Selcect your C++ Project –> right click
2. Code Assistance -> Reparse Project

Edit:

I tested the methods with the following code under NetBeans 7.3 RC1 (using GCC 4.7.2):

#include <iostream>
#include <list>

int main ()
{
  std::list<int> mylist = {5,10,15,20};

  std::cout << "mylist contains:";

  for (auto it = mylist.cbegin(); it != mylist.cend(); ++it)
    std::cout << ' ' << *it;

  std::cout << '\n';

  return 0;
}

With C++ Standard set to default this fails, but with C++11 (Project Properties -> Build -> C++ Compiler -> C++ Standard = C++11)it works.
