Как настроить сборку C++ для C++ 11

Question

Я пытаюсь создать и установить MGSim simulator из исходного кода. Для этого я ввел следующую команду конфигурации:
[root@dhcppc2 build-mtalpha]# ../configure --target=mtalpha --disable-trace-checks --prefix=/home/mehdi/mgsim CXX=g++ CPPFLAGS=-std=c++0x

Я думаю, что включили поддержку C++ 11, обеспечивая флаг `C++ 0x», но я все еще получаю следующее сообщение об ошибке:

configure: error: *** A compiler with support for C++11 language features is required.

Я ввел другие альтернативы для C++ 0x, такие как C++ 11, g ++, gnu-0x и т. Д., Но никто не работал.

В сценарии configure упоминается отсутствие поддержки потоков на линии непосредственно перед ошибкой. Я сомневаюсь, что это совпадение.
