When using gdb with M-x gdb, the *input/output* buffer always pops up aggressively in any frame which has focus and isn't already displaying it. I would like the *input/output* buffer to stay quietly in the background unless I manually bring it up.

Here's a very simple example with emacs -Q

run M-x gdb. give a program of bash and hit Return

in the *gud-bash* window, enter run -c "while true; do echo hi && sleep 1; done"

Notice how the *input/output of bash* window pops up. If you dismiss that buffer with C-x 1 from the *gud-bash* window, it comes back as soon as gdb produces any more stdout. That's the behavior I don't want.

In particular, now run M-x make-frame (from the *gud-bash* window). Notice how in the new frame, *input/output of bash* also pops up! So it demands one window out of every single emacs frame.

How can I fix this?

Edit: I almost forgot to add - emacs version of

GNU Emacs 24.5.2 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.30)

As soon as emacs 25 lands, there will be a variable gdb-display-io-nopopup to fix this problem

split emacs window into three (c-x 3), and assign one window to the input/output buffer (c-x b, input/output)

Stops the popup, and program output is displayed in the "input/output" buffer window

  • Clarify what you mean by "screen", and by "assign". Also I'm not sure it addresses the issue that the debugger code forces you to have the input/output buffer displayed in a window in each frame. – Stefan Oct 5 '18 at 12:27
  • split emacs windows: (c-x n), assign buffer to a window (c-x b) – Paul Salber Oct 5 '18 at 12:56
