One more thing not shown: Attach GDB to a GUI program by clicking on it. I have this in my setup: python import gdb import subprocess class AttachOnClick(gdb.Command): def __init__(self): super(AttachOnClick, self).__init__('attach_onclick', gdb.COMMAND_RUNNING, gdb.COMPLETE_NONE) def invoke(self, arg, from_tty): if not from_tty: print('Only supported in interactive mode (from tty)') return if arg: print('No arguments supported') return xprop = subprocess.Popen(['xprop'], stdout=subprocess.PIPE) awk = subprocess.Popen(['awk', '/^_NET_WM_PID/{print $3}'], stdin=xprop.stdout, stdout=subprocess.PIPE) xprop.stdout.close() try: bpid = awk.communicate(timeout=60)[0] except subprocess.TimeoutExpired: print('No click within 60 seconds, giving up') xprop.terminate() awk.terminate() awk.wait(1) xprop.wait(1) return awk.wait(1) xprop.wait(1) spid = bpid.decode('ASCII').strip() if not spid: print('No pid could be obtained') return cmd = 'attach ' + spid gdb.execute(cmd, True) AttachOnClick() end Then you can type attach_onclick at the gdb command prompt and just click on a window to attach to it.
