I have this sample code and it throws an error:

std::random_device rd;     // only used once to initialise engine
std::mt19937 rng(rd);      // random-number engine used
std::uniform_int_distribution<int> uni(0, 7); // guaranteed unbiased

int random_integer = uni(rng);

The error is:

Error 1 error C2039: 'generate' : is not a member of 'std::random_device' c:\program files (x86)\microsoft visual studio 12.0\vc\include\random 1618 1 Life

Can somone explain me please, why is this happening? It seems to be an error in the header file and not in my code.

How can I fix it?

Thank you.
