How to compile C++ is_pod?

[Peng Yu]

Hi,

http://www.cplusplus.com/reference/type_traits/is_pod/

I'm trying to compile the above code. But I get the following error.
Do I use the correct option for gcc-mp-4.7. Or there is some error
with my gcc-mp-4.7 installation? Thanks.

~/linux/test/cpp/cpp/library/type_traits/is_pod$ gcc-mp-4.7 -std=c++11
-o main main.cpp
