gdbserver for GNU/Hurd

Hello!

Has anyone ever worked on porting the GDB distribution's
gdbserver to
GNU/Hurd?

In case you don't know: this would allow for debugging
programs on
GNU/Hurd systems using a cross debugger running on another
system (e.g. a
non GNU/Hurd one).  This is of advantage if you're cross
compiling and
then don't have to copy the source files to the target
system for using
gdb locally on there.


Regards,
 Thomas

If you have any reports about gdbserver not working on
GNU/Hurd then
report them here so that they can be fixed.

Uhm, that's exactly what I did in my original email, you may
want to
re-read it:

#v+
$ ../configure
[...]
Error: target not supported by gdbserver.
$ ../../../config.guess 
i686-unknown-gnu0.3
#v-

I'm pretty sure the answer to that question is no.

But it'd be difficult to have access to all the advanced
features a
native GNU/Hurd GDB offers.

As far as I know.

It shouldn't be hard to add anything necessary to the remote
protocol
and if anyone was interested in working on it I'd be glad to
offer
advice.

I'm looking at this just for "fun".  Should we add
our own hurd-i386-foo 
files or gnu-i386-foo, or try to shoehorn our stuff into
using something 
like linux-i386-low?

Thanks,

You probably want a gnu-i386-low.c.  I don't think you'll be
able to
share much with the Linux support at all.
