patching kdb to the Centos Kernel : more errors

[Satish Eerpini]

i have fixed up errors concerning the previous ones i have mentioned
, ... but new  errors have appeared , :

  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  CHK     include/linux/compile.h
  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
kdb/built-in.o: In function `kdb_inittab':
/usr/src/redhat/BUILD/kernel-2.6.18/linux-2.6.18.i386/kdb/kdbmain.c:3816:
undefined reference to `__kdb_initcall_start'
/usr/src/redhat/BUILD/kernel-2.6.18/linux-2.6.18.i386/kdb/kdbmain.c:3822:
undefined reference to `__kdb_initcall_end'
make: *** [.tmp_vmlinux1] Error 1

i have checked the code which corressponds to the above errors , it is
something liket this :

	/* Any kdb commands that are not in the base code but are required
	 * earlier than normal initcall processing.
	 */
	call = & __kdb_initcall_start;
	while (call < & __kdb_initcall_end) {
		(*call)();
		call++;
	};

, but i don't understand why it is showing an undefined reference
error , __kdb_initcall_start and __kdb_initcall_end are defined in
include/linux/kdbprivate.h as follows :

#ifdef	MODULE
#define kdb_module_init(fn) module_init(fn)
#define kdb_module_exit(fn) module_exit(fn)
#else	/* !MODULE */
extern initcall_t __kdb_initcall_start, __kdb_initcall_end;
#define kdb_module_init(fn) \
	static initcall_t __kdb_initcall_##fn __attribute_used__
__attribute__ ((__section__ (".kdb_initcall.init"))) = fn;
#define kdb_module_exit(fn) \
	static exitcall_t __kdb_exitcall_##fn __attribute_used__
__attribute__ ((__section__ (".kdb_exitcall.exit"))) = fn;
#endif	/* MODULE */

then what does the error signify ?


Thanks
