string variables

Still wrong.
The following code compiles without warnings:

#include <string>

using namespace std;

int main(void)
{
        string a = "test";
        return 0;
}

{

your code returns errors like those:

I don’t know why
Maybe some settings?
My target is cortex m3
Any idea?

Embedded programming is not so easy, eh?
You should start with an example program that closely matches your target hardware. Once you get it to compile and run, you can start making modifications.

If it can be done, this is all I need to know.

A simple thanks is not enough
A honest one is better.
Thanks Mike
