literal suffix for string not compiling

[JUAN DENT]

I have:

#include <string>

using namespace std;


void f()
{
      auto x = "hello"s;
}

and the compiler complains about the suffix s.

it says:

error C3688: invalid literal suffix 's'; literal operator or literal operator template 'operator ""s' not found

What am I doing wrong?

It's defined in the namespace std::literals::string_literals.

void f()
{
	using namespace std::literals::string_literals;
	auto x = "hello"s;
}
