c++ - Multiple Errors Building Deck of Cards -

receiving 2 errors trying compile files. (received down vote without explanation; fail see how violates guidelines.)

1) c:\mingw\lib\gcc\mingw32\4.9.3\include\c++\bits\c++0x_warning.h:32:2: error: #error file requires compiler , library support iso c++ 2011 standard. support experimental, , must enabled -std=c++11 or -std=gnu++11 compiler options i attempted add flags in eclipse mars, doesn't seem have worked. thing i'm missing?

2) \deckofcards.h:21:8: error: 'array' in namespace 'std' not name template type this in regards std::array<card,52> cards_; line in deck of cards header file. first time attempting build deck of cards multiple classes...or single class matter if i'm making obvious error apologize.

edit: exact message compiler:

07:56:55 **** incremental build of configuration debug project texasholdem **** info: internal builder used build g++ -o0 -g3 -wall -c -fmessage-length=0 -o texasholdemmain.o "..\\texasholdemmain.cpp"  in file included c:\mingw\lib\gcc\mingw32\4.9.3\include\c++\array:35:0,                  ..\deckofcards.h:11,                  ..\texasholdemmain.cpp:5: c:\mingw\lib\gcc\mingw32\4.9.3\include\c++\bits\c++0x_warning.h:32:2: error: #error file requires compiler , library support iso c++ 2011 standard. support experimental, , must enabled -std=c++11 or -std=gnu++11 compiler options.  #error file requires compiler , library support \   ^ in file included ..\texasholdemmain.cpp:5:0: ..\deckofcards.h:21:8: error: 'array' in namespace 'std' not name template type    std::array<card,52> cards_;         ^  07:56:56 build finished (took 233ms) 

if recompile second time after receiving these errors without changing receive ton more errors everywhere else across multiple files; normal?

you have set -std=c++11 flag gnu compiler.

according eclipse forums:

1. right-click project , go "properties"
2. go to: c/c++ build -> settings -> tool settings -> gcc c++ compiler -> miscellaneous -> other flags.
3. put "-std=c++11" @ end.
