"undefined reference to `std::ios_base::Init::Init()" while compiling a hello world in netbeans

I am new to ubuntu and I want to code in C++. I intalled g++ through software manager and after I installed netbeans to have a nice IDE to code in C++. Then I write this simple code:

#include <iostream>
//using namespace std;
int main(int argc, char**argv) { // Prints welcome message... std:: cout << "Welcome ..." << std::endl; // Prints arguments... if (argc > 1) { std::cout << std::endl << "Arguments:" << std::endl; for (int i = 1; i < argc; i++) { std::cout << i << ": " << argv[i] << std::endl; } } return 0;
}

When I built the code I got this error:

/usr/include/c++/4.8/iostream:74: undefined reference to `std::ios_base::Init::Init()'

This meaning that isn't my code in error bu It seems that iostream refer something that is unknown.

Now, my question is: how I can check if gcc and g++ are installed correctly? And, if it is installed well, why g++ doesn't compile?

It is very strange. You need open "Project Properties" window and change Build|Linker|Tool from gcc to g++

p.s. I have no probs compiling code with g++, while I get same kind of errors trying with gcc.
