hello linux experts,

this seems like a simple thing, but how to build linux in debug (-g) mode?

I need to do this:

$ cd /usr/src/linux ; gdb vmlinux /proc/kcore

but I think kernel needs to be build with -g for the kernel symbols
to be there.

the obvious thing (edit /usr/src/linux/Makefile) and added -g to the
HOSTCFLAGS (near the top of the file), and recompile, did not do it.

what is the best way to do it?

thanks,
Nasser
