:Yes, the FreeBSD guys (not me) have made considerable progress with
:loading kernel symbols, though at the moment (since the introduction
:of gdb 6.x) things are a bit of a jumble. In many cases it's possible
:for the symbols to load automatically without user intervention; I
:think this is the case for those lucky enough to be able to get a
:processor dump (currently 'panic' in ddb doesn't work; use 'call
:doadump' to get a dump).
:> Check Greg's various gdb setup files:
:This is a little out of date. Now more generic scripts are in
:/usr/src/tools/debugscripts. You should be able to go to the kernel
:build directory (typically something like /usr/obj/usr/src/GENERIC)
:Karlsruhe on Friday. After that, I'll release the course notes
:(hopefully with corrections).
Thanks for responding, Greg! Joerg is in the midst of a number of
gdb-related items too. Now that we know where to look I expect we
will be able to integrate something in.
