Eclipse CDT C++11/C++0x support

I tried everything to compile C++11 code namely std::unique_ptr and it never compiles.

I followed this and this yet it still doesn’t compile. I also installed gcc 4.7, and made sure that it’s added to the includes directories of my eclipse c++ project, yet it still doesn’t work!!

Is there anything missing please?

Answer 1

Which language standard GCC defaults to depends on how it has been compiled, but most distributions still set this to something like gnu++98 for C++. To use C++11, you have to pass one of the following language standard options:

g++ --std=c++0x     # <= 4.6.*

g++ --std=c++11     # >= 4.7.* (but c++0x is still accepted)

To use a unique pointer:

#include <memory>

std::unique_ptr<base[]> AllYourBase(::new base[1024]);
