GDB – Display output of target application in a separate window

For people wondering how to use the GDB tty command here is a short description…

• Open a new console window. We will redirect output from the program running under GDB here. This is our output window.

• Run the tty command in the output window. This will show the name of the tty being used by the underlying console.

  $ tty
/dev/pts/4

• Open another console window and start GDB here. Let us call this the GDB window.

• Now run the tty command in GDB using the tty file name obtained above and then start the debugging process.

  (gdb) tty /dev/pts/4
(gdb) run

Now you should be able to see the program output separately in the output window.

Note: The GDB set new-console on command does not work on Linux! It is meant to be run on windows only. Use the tty method described above on Linux.
