Hi, I want to have maximum debugging symbols in my kernel image and currently I have changed the build flags in my top level Makefile so that they look like below.
HOSTCFLAGS = -Wall -Wstrict-prototypes #-O2 -fomit-frame-pointer #HOSTCXXFLAGS = -O2 ifdef CONFIG_CC_OPTIMIZE_FOR_SIZE CFLAGS += -DMANISH -Os else CFLAGS += -DMANISH #-O2 endif include $(srctree)/arch/$(ARCH)/Makefile ifdef CONFIG_FRAME_POINTER CFLAGS += -fno-omit-frame-pointer -fno-optimize-sibling-calls else CFLAGS += -DMANISH #-fomit-frame-pointer endif ifdef CONFIG_DEBUG_INFO CFLAGS += -g endif I also have the frame pointers configured. /home/mkatiyar/personal/uml/linux-2.6.23.12> grep CONFIG_FRAME_POINTER .config CONFIG_FRAME_POINTER=y I even tried -g3 , but still while debugging for some symbols gdb says "value optimized out". I am using UML for debugging. Any other suggestions which I can change in my Makefile so that gcc doesnt optimize anything and provides me with the maximum info. I doubt but can that be related to UML in anyway , because while building I have to give "arch=UM" ? -- Thanks & Regards, ******************************************** Manish Katiyar ( http://mkatiyar.googlepages.com ) 3rd Floor, Fair Winds Block EGL Software Park Off Intermediate Ring Road Bangalore 560071, India *********************************************** ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
