[Qemu-devel] Using GDB with Qemu : No Symbol Table?

[Atoosah]

Hi

Thank you for your help, but I think my question was misunderstood.

Debugging the kernel is not my goal. Instead, I want to debug qemu itself. i.e. I want to be able to add watchpoints/breakpoints to qemu source code. How do I compile Qemu to enable the symbol table? 

My difficulty is that I need to be able to make install my_qemu (i.e. the installed qemu version). Correct me if I'm wrong, but the -s -S options are necessary if the goal is debugging the kernel. Is there a patch available, such as the one provided in http://www.h7.dion.ne.jp/~qemu-win/DebuggingTips-en.html/ (which seems to be a rather old link)?

Thanks again.

try to compile your kernel with CONFIG_DEBUG_INFO=y and
CONFIG_FRAME_POINTER=y. Both will enable gdb to easily resolve symbol
names into addresses and tracking down function call chain in stack
frame.
