gdb trick: automatically redirecct output to another terminal

tty command in gdb can direct output to another terminal.

Like https://stackoverflow.com/questions/8963208/gdb-display-output-of-target-application-in-a-separate-window

But I want it to be set automatically.

Method

Create a script ~/.gdbtty.sh

Its content

#!/bin/bash

gnome-terminal -- bash -c "tty > ~/.gdbtty.txt; exec bash" &

sleep 0.5  # Give it time to open

TTY=$(cat ~/.gdbtty.txt)

echo "set inferior-tty $TTY" > ~/.gdbtty.txt

And edit ~/.gdbinit as

shell ~/.gdbtty.sh

source ~/.gdbtty.txt

Some shortcomings

It's good but with some tiny shortcomings that I currently can't solve.

1. I cannot control where the output terminal would popup. (But even I can control, I have no idea where is the ideal position for me)


2. The output terminal may show a harmless warning "warning: GDB: Failed to set controlling terminal: Operation not permitted"
