Undefined Reference to deck::array1 in c++ : <p>I have header file in which I have static function which are public and i have a private static array. In my c++ file file i am calling my array from one of this static function and getting error "UNDEFINED REFERENCE TO abc::ARRAY". why I am getting this error?
When I remove static from array and function it works properly. But I need to make them static to use in another c++ file</p>
