C ++ autonomous functions

Question

What features can I use in a standalone C ++ environment? I am developing a small kernel (for my own pleasure), and I know that I cannot use the entire stdlib library, but what else? when I tried to use the new and deleted operators, which he compiled without problems, but the linker said

undefined reference to `operator new[](unsigned long)
undefined reference to `operator delete[](void*)'

I am contacting the parameters -lgccand -lsupc++. I know that exception handling is disabled offline, but I'm a little surprised that new and deleted too. So what can I use and what not?
