Random number generation (what's missing?)

I have tried a simple example straight off the Microsoft website Link in order to try to figure this out, but it won't compile for me. I just want to create a uniformly distributed random number (long long). I think I may be missing something, but I have no idea what.

#include <random>
#include <iostream>

using namespace std;
using namespacestd::tr1;
//typedef std::tr1::random_device rd;

int main()
{
    random_device rd;   // non-deterministic generator
    mt19937 gen(rd());  // to seed mersenne twister.
    uniform_int_distribution<> dist(1,6); // distribute results between 1 and 6 inclusive.

    for (int i = 0; i < 5; ++i) {
        cout << dist(gen) << " "; // pass the generator to the distribution.
    }
    cout << endl;
}

Open in new window

Here are the errors I am getting.

I would appreciate any insight. I am using VS2008 w/SP1.

Thanks,
Elena

phoffric,

Does that mean it doesn't work in 2008 with SP1? When initially researching this on the Microsoft site, the <random> included 2008. But then I read on another question somewhere that I had to install SP1. So I did that.

I kinda need it to work with 2008, unfortunately. The developers I am working with are only using that. Tried to get them to switch to 2013, but no go.

Thanks,
Elena

BTW, I did try rand() with not much success. The distribution is not uniform at all. See the pic of a distribution of 1000 tries.
