Rafael, I don't think anyone has tried compiling kgdb for mac mini.
Functions reported as undefined are defined in arch/ppc/kernel/kgdb.c file in powerpc-lite.patch This file is included in vmlinux compilation because of following part of the same patch -> --- linux-2.6.17.orig/arch/powerpc/kernel/Makefile 2006-07-06 13:12:37.000000000 +0530 +++ linux-2.6.17/arch/powerpc/kernel/Makefile 2006-07-06 14:22:17.000000000 +0530 @@ -59,6 +59,7 @@ obj-$(CONFIG_SMP) += smp.o obj-$(CONFIG_KPROBES) += kprobes.o obj-$(CONFIG_PPC_UDBG_16550) += legacy_serial.o udbg_16550.o +obj-$(CONFIG_KGDB) += kgdb.o module-$(CONFIG_PPC64) += module_64.o obj-$(CONFIG_MODULES) += $(module-y) I guess you would have applied this powerpc-lite.patch Can you think of the reason why kgdb.o was not compiled? -Amit On Friday 18 August 2006 00:08, Rafael Garabato wrote: > Hi, > > I am trying to compile kgdb for a mac mini.
