Dear Sir,
Thank you very much. I will look in depth and raise the question if I get.

If  theread support is disabled, then also gdb server side does  the
symbolic address finding ? I think not, am I right ? please clarify me.

How can I get all the gdb mailing list into my inbox ? like rtems.

Regards
Raja Saleru

If you look at the linuxthreads_db/ directory in glibc source, you'll
see the trick - thread_db_init calls back into the application. Take a
look at gdbserver/proc-service.c, function ps_pglobal_lookup.

When you build gdbserver, does configure find libthread_db?  Does it
get linked to libthread_db.so?
