How to hard-code vector initialization for vector of struct vectors?

The following class gets this compile error:

What is the proper way to hard-code vector initialization for vector of struct vectors?
I am using g++ (GCC) 6.2.1 20160916 (Red Hat 6.2.1-2).

Thank you.

Your code would have worked if name and scancode were simply strings. Now they are vectors so you need to add an extra pair of curly brackets around them.

scancodes =
    {     //type            name, scancode
        { "Code_Shift", { {{"s_shift"}, {"MODIFIERKEY_LEFT_SHIFT"}} } },
        { "Code_Sc",    { {{"s_a", "KEY_A"}}, {{"s_b", "KEY_B"}} } }
    };

Thanks Peter87. Name and scancode were suposed to be strings.
You saved the day.
