c++ - How can I update code::blocks to use TDM-GCC?

Question

I need to use unique_ptr in my C++ assignment.

I downloaded a new compiler, TDM-GCC-4.7.1, and installed it. Then I changed the directory of GNU GCC Compiler to the installation path in option: Setting->Compiler...->Toolchain Executable.

But it doesn't work. When I define a unique_ptr. A error would occur: "unique pointer is not a command of 'std' "

The reason of using smart pointer is to provide strong exception safety, which is also a requirement of this assignment. I just need to use this new feature of C++11... Plus, the OS I use is Window 7.

Thanks!

In CodeBlocks you can set C++11 mode either in project compiler settings or global compiler settings. Since you may be using it more often, here is how you change it globally:

Go to Settings -> Compiler -> (There should be list of options here, in Compiler flags) -> Select "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]"

Here is how to change it for a single project:

Go to Project -> Build options -> (There should be list of options here, in Compiler flags) -> Select "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]"
