ARM Remote GDB 6.0

ARM Remote GDB 6.0

[Chris.Pedley]

I've just given remote debugging a go with GDB 6.0 in the hope that
multi-threaded remote debugging might now work.  I still can't get it to
work.  I've configured gdb with:
configure --host=i686-linux --build=i686-linux --target=arm-linux

gdbserver has been configured with:
export CC=arm-linux-gcc
configure arm-linux

I get the following trying to run to a breakpoint on a thread called
hello_world:

(gdb) cont
Continuing.

Program received signal SIG32, Real-time event 32.

Most annoyingly of all though, when I quit gdb, gdbserver on the target
side logs me out!

Any ideas what is going on? I'm a bit worried about:
'Function "internal_error" not defined'

Thanks.

Can't help you on the rest of your problem, but this is nothing to worry 
about.  When gdb starts up it will execute the contents of any .gdbinit 
file in the current directory.  In this case you most likely have a file 
that contains

break internal_error

in it on line 5.  Since the program you are trying to debug here isn't the 
one the script was written for it's trying to set a breakpoint on a 
function that doesn't exist and so generating an error.

R.

Please read the archives of this list for more information on what
you're supposed to do to set up remote thread debugging.  You haven't
told GDB where your libraries are.

I _think_ I fixed this in CVS after 6.0.  I don't remember what the
problem was, though, so I'm not sure.
