Your reply will be greately appriciated. Thanks in advance.

The server uses it when it needs the address of a symbol. This is in
the GDB manual, in the Remote Serial Protocol appendix.

qSymbol is a mechanism _for the target_ to ask the _host_ about the
address of a symbol. You appear to have the opposite problem, so you
will need something different.

Hello Sir, the following is the function definition,
static void
linux_look_up_symbols (void)
{
#ifdef USE_THREAD_DB
if (using_threads)
return;
using_threads = thread_db_init ();
#endif
}
assume that I am interested in only process debugging, but not thread
debugging,
so I am not defining USE_THREAD_DB macro.
I am getting confuse... why target sending symbols to host (gdb ) ?
If I compile the application at host side as re-locatable and relink it at
target side, the sybols are there at host side only.
the corresponding values at target side. This is what I thought.. what will
be solution in this case ?
can you carrify me more in details ?
Regards
Raja S

Other way around, friend. Values of symbols are sent _to_ gdbserver.
See linux_look_up_symbols.

Yes, I got it in manual. Thanks for the same.
In GDB Server, I think currently return only "OK".
Does any implementation of qSymbol in GDB Server to send the values of sybols to host side gdb ?
If not, how we can implement the same ? any example or algorithmic way of representing what needs to be implement ?
Regard
Raja S
