I'm using the pc386 BSP using Qemu with the pc386 script provided on 
rtems_testing. Only today I tested GDB with Qemu, which I'm finding a 
bit tricky with the pc386 script because as soon as the program finishes 
It closes Qemu, so I can't connect to the gdb server. To solve that I 
used the instructions on the Wiki about Qemu (which seems to be a little 
outdated, so I needed to change some steps) and I can now load a program 
and connect to the gdb server, but I don't have the symbol table for any 
program. I can't recall enabling debugging during the rtems configure 
stage, but will that generate symbol tables for every compiled program? 
Can't I just generate a symbol table for a specific program?

In that case that's where I'm going to start. Any questions that I might 
have should I post them on the users list or somewhere else?
