I thought typeid can work at compile-time without rtti (seems to for msvc8) but I guess not.

Any ideas?

So I take it there is no flags for gcc to enable compile-time rtti only and there are no other ways around the typeid error in shared_ptr's implementation.

If you don't need to use get_deleter, just patch your local copy to 'return 0' from the three functions.
