Hello,
I'm trying to get PDB working in accordance with the instructions at
http://www.cl.cam.ac.uk/~sos22/replay.bk/docs/misc/XenDebugger-HOWTO and
a message from this list:
http://lists.xensource.com/archives/html/xen-devel/2004-08/msg00017.html
When I try to build pdb I first get errors because the Makefile is
configured to treat warnings as errors, and there are some warnings. I
decided to take my chances, and I removed Werror from CFLAGS in
tools/debugger/pdb/Makefile. At that point, the build failed because it
is unable to find xcs_proto.h. After some googling, it seems this
existed in the xen-unstable.hg tree earlier this month.
Is the PDB system currently broken?
Thanks,
-Jon
