I am compiling a kernel for my raspberry pi (on the pi). I checked necessary configuration and enabled DEBUG_INFO=y and REDUCED_DEBUG=n.
But when I issue the command make I get the following error:
scripts/kconfig/conf --silentoldconfig Kconfig

I could build my kernel and reboot it properly without the DEBUG_INFO etc. ( actually I had forgot to enable them) and I could load a module also.
How can I enable debugging feature and make this build. I Intend to write gpio drivers later.
Edit: Comment:
The Makefile has following for DEBUG_INFO:
ifdef CONFIG_DEBUG_INFO
KBUILD_CFLAGS += -g
KBUILD_AFLAGS += -gdwarf-2
endif
ifdef CONFIG_DEBUG_INFO_REDUCED
KBUILD_CFLAGS += $(call cc-option, -femit-struct-debug-baseonly) \
$(call cc-option,-fno-var-tracking)
endif
But I don't get it...what is this -femit-struct-debug-baseonly, -fno-var-tracking
