Многочисленные ошибки при построении колоды карт

Получаю две ошибки при попытке скомпилировать мои файлы. (Получил отрицательный голос без объяснения; я не вижу, как это нарушает какие-либо рекомендации SO.)

1) c:\mingw\lib\gcc\mingw32\4.9.3\include\c++\bits\c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options Я попытался добавить флаги в Eclipse Mars, но, похоже, это не сработало. Может быть, это единственное, чего мне не хватает?

2) \DeckOfCards.h:21:8: error: 'array' in namespace 'std' does not name a template type Это касается std::array<Card,52> cards_; строка в моей папке колоды карт. Я впервые пытаюсь собрать колоду карт из нескольких классов … или одного класса в этом отношении, поэтому, если я делаю очевидную ошибку, я прошу прощения.

Если я перекомпилирую второй раз после получения этих ошибок, ничего не меняя, я получу гораздо больше ошибок повсюду в нескольких файлах; это нормально?
