Does linaro toolchain support c++11 ??

[zhangwentao (M)]

Hi all,

I wonder if my compiler supports C++11? If not, where could I found the compiler supports c++11 (both 32bit and 64bit arm).

THANKS a lot~~~

My compiler information is as below:

And more, I wrote a "hello-world" program using c++11, it could work with host g++, but when I change to "arm-eabi-g++", it does not work.
Information as below:

***@ubuntu:~/test/lamda$ cat a.cc
#include <iostream>
using namespace std;

typedef void(*Func)();
int main()
{
Func f = [=]() {
cout <<"Hello world"<<endl;
};
f();
return 0;
}
***@ubuntu:~/test/lamda$ g++ a.cc -o host

a.cc:10:2: warning: lambda expressions only available with -std=c++11 or -std=gnu++11 [enabled by default]
