Creating C++ FreeRTOS Project

Hi, 
I want to create new project for Renesas RX66T MCU and use C++ and FreeRTOS. But after creating, new project is still on C language. What I need to do to change the language? I used GCC compiler.
P.S. I noticed that without FreeRTOS i can create C++ project, but with FreeRTOS it not worked. 
Thanks
