Configuring C++11 in Netbeans

问题

I am using Netbeans 7.2, and I have downloaded GCC 4.7 using the Cygwin setup. I have also added the directories to my PATH and I believe configured the settings in NetBeans appropriately. No matter what I do, I get the error: -std=c++11 not recognized.

This line, from source code that I need to use, is particularly causing problems:

using size_type = long unsigned int;

Is this specific to c++11 syntax?

回答1:

With GCC 4.7.2 it compiles if you use the -std=c++11

C:\Users\ferenc>type using_test.cpp
#include <iostream>

using size_type = long unsigned int;

int main(int argc,char* argv[])
{
        std::cout<<sizeof(size_type)<<std::endl;
        return 0;
}

C:\Users\ferenc>g++ -std=c++11 using_test.cpp

C:\Users\ferenc>a.exe
4

C:\Users\ferenc>

1. Make sure that you have pointed NetBeans to the correct MinGW version. To do that, go to Project Properties > Build > Tool Collection > ... > Tool Collection Manager and there you can set the path to the proper g++ version.

2. Make sure that you have set the correct compiler options:

   Project Properties > Build > C++ Compiler >

   Compilation Line > Additional Options

   set it to: -std=c++11

Simpler Steps:

1. Open the project
2. File menu > Project Properties
3. Under Build > C++ Compiler > C++ Standard > C++14/ C++11
