Hi all, I am trying to use gdb for debugging kernel. My intention is just to go thru different kernel data structures. I am getting the following error. #gdb /boot/vmlinuz-2.6.5-1-debug.358 /proc/kcore GNU gdb Red Hat Linux (6.0post-0.20040223.19rh) Copyright 2004 Free Software Foundation, Inc.

(gdb) q ---------- I have compiled the kernel with CONFIG_DEBUG_INFO set to y. Even googling the error didnt help. Please tell me what could be the problem. Am I missing something?
