Cannot find bounds of current function

Cannot find bounds of current function

[Buday Gergely]

Hi,

I'm to use remote debugging via gdbserver on my Ubuntu linux box.

I've compiled my program with the -g gcc option. Then started

$ gdbserver host:10000 a.out

From the same machine I started gdb and told her

(gdb) target remote localhost:10000
Remote debugging using localhost:10000
0xb7febc20 in ?? ()
(gdb) n
Cannot find bounds of current function

I've googled a bit and found that I should use add-symbol-file at the gdb 
client. I've used an object file with debug information to load (not sure 
about this one) but was totally inept to figure out what address should I 
give as a second argument. Do you have any hint where I can get a proper 
address from? Or, any advice how should I set up my remote debugging 
session?

No, don't mess with add-symbol-file.  You aren't in a function: you're
at the executable's starting point.  Try setting a breakpoint at main
and continuing.
