Am relatively new to the linux kernel. I have a problem patching the
linux kernel with the kdb kernel debugger.... Here are the steps i
followed. Am not sure if i have missed anything... Kindly help me
out...
1) Untarred the linux-2.6.9 to my home directory
[srikanth@zeus linux]$ pwd
/home/srikanth/work/src/linux
2) Copied kdb-v4.4-2.6.9-i386-1 to /home/srikanth/work/src/linux
3) [srikanth@zeus linux]$ patch -p1 < kdb-v4.4-2.6.9-i386-1
patching file arch/i386/Kconfig.debug
patching file arch/i386/Makefile
patching file arch/i386/kdb/ChangeLog
patching file arch/i386/kdb/Makefile
patching file arch/i386/kdb/i386-dis.c
patching file arch/i386/kdb/kdb_cmds
patching file arch/i386/kdb/kdba_bp.c
patching file arch/i386/kdb/kdba_bt.c
patching file arch/i386/kdb/kdba_id.c
patching file arch/i386/kdb/kdba_io.c
patching file arch/i386/kdb/kdbasupport.c
patching file arch/i386/kdb/pc_keyb.h
patching file arch/i386/kernel/entry.S
patching file arch/i386/kernel/i8259.c
patching file arch/i386/kernel/io_apic.c
patching file arch/i386/kernel/reboot.c
patching file arch/i386/kernel/smp.c
patching file arch/i386/kernel/smpboot.c
patching file arch/i386/kernel/traps.c
patching file arch/i386/kernel/vmlinux.lds.S
patching file include/asm-i386/ansidecl.h
patching file include/asm-i386/bfd.h
patching file include/asm-i386/kdb.h
patching file include/asm-i386/kdbprivate.h
patching file include/asm-i386/kmap_types.h
patching file include/asm-i386/mach-default/irq_vectors.h
patching file include/asm-i386/ptrace.h
patching file kdb/modules/kdbm_x86.c
4) Ran menuconfig and chose Built-in Kernel Debugger support from
Kernel hacking.
I alos chose KDB modules to be built.in
5) Then when i ran make bzImage i got the error as linux/kdb.h not found
[srikanth@zeus linux]$ make bzImage
