Re: Elf debugging

[maybedoo <maybedoo@gmx.de>]

Hi, I'm sorry this is the first time I'm posting here.

Host is a Linux Debian Lenny System and target also the same machine.

 - gcc version: gcc (Debian 4.3.2-1.1) 4.3.2
 - gdb version: GNU gdb 6.8-debian

The gdb is the preinstalled on the system.

To compile the elf I've used make with the following command: 

makedefine CFLAGS := $(CPU_OPT) $(DISTRO_CFLAGS) $(CPPFLAGS) -O2 -g
-nostdinc -nostdlib -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs
-Werror-implicit-function-declaration -Wstrict-aliasing -Wshadow -fno-common
-ffreestanding -fno-builtin -fomit-frame-pointer

Here is the log how I connected to the elf:

(gdb) file
/home/sphinx/coreboot/coreboot-v2/targets/emulation/qemu-x86/qemu-x86/normal/coreboot_ram
Reading symbols from

(port));
(gdb) search elfboot

(gdb) break elfboot.c:20
No source file named elfboot.c.
Make breakpoint pending on future shared library load? (y or [n]) n

I've attached the readelf log, hopefully it says something to you.

Thanks for your help Paul.

Regards,

May
