I have tried 3 days, switch compilers, linking scripts ...
to make a simple C++ program working on LPC1768 with G++, but failed.

1

#include <iostream>

2

#include <string>

3

using namespace std;

4

int main()

5

{

6

    std::string str = "foo";

7

    std::cout << str << std::endl;

8

    return 0;

9

}

Anymore can show me the right version of cm3 files/linking scripts/gcc 
and ld option to make this program succeed return? I got this program 
compiled but hang while string assignment. And I need using G++ 
toolchains sourcery or yagarto or linaro with G++ version 4.6+.
