  1. You don't actually have a problem, since it's unlikely that you want to step into libc implementation to start with, but ...
  2. If you really do want to step into libc code, you need to install GIBC source, and tell GDB where that source is installed (using GDB dir command).

  • So just ignore this prompt message, and my program won't be affected by this message in the future, right? – lanxu yang Jun 20 '23 at 15:35
  • @lanxuyang Correct. You have stepped out of `main`, so there is nothing else to debug (except possibly global destructors). You can just `continue` and your program should exit. – Employed Russian Jun 20 '23 at 16:27
