[Xen-devel] a problem when I'm try to debug xen boot codes

["wu ming" <wmy_dev@xxxxxxxxxxx>]

hi,
I want to learn xen boot codes. I use bochs with gdb stub to implement 
source codes debug.
I rebuild xen kernel with "debug=y, debugger=y" to enable debug, boot xen 
by bochs, connect gdb remote target, set breakpoint. All are ok now.(I run 
gdb in directory "xen", and set breakpoint at __start_xen.)
But, when the breakpoint is hit, gdb displays:"setup.c:no such file or 
directory". Of course, I can use directory to add search path to gdb. But 
if trace into a different directory, I have to use "direcotry" again. You 
know, the directory structure is some complex, so it's so boring to add all 
directory to gdb.
As I know, some debug information of elf file includes directory of file. 
But there is just only the file name without directory.
Does anybody know how to deal with it?
Thanks.

Ming
