use --openpty to activate openpty mode konsole --openpty /dev/pty1 IIUC, something similar can be achieved via: konsole --noclose -e /usr/bin/tty (In reply to ninjalj from comment #2) > IIUC, something similar can be achieved via: > > konsole --noclose -e /usr/bin/tty A human can copy and past such slave name of the pty. How a program, like IDE(Eclipse CDT) get that slave name? The only way is through stdout. https://gitlab.gnome.org/GNOME/gnome-terminal/-/issues/7951 https://github.com/mintty/mintty/issues/1187 On Linux something like the following would output the tty device name. The sleep may need to be tweaked.
die()
{
echo "$@" >&2
exit 1
}
konsole --noclose -e /usr/bin/tty &
konsolepid=$!
sleep 1
for fd in /proc/$konsolepid/fd/*
do
[ "x$(readlink $fd)" = x"/dev/ptmx" ] && ptmx=$fd && break
done
[ -z $ptmx ] && die "konsole process doesn't appear to have opened a pty master"
ptmx=${ptmx/fd/fdinfo}
awk -F: '/tty-index/{ print "/dev/pts/"$2+0 }' $ptmx
Figured out a way to work partially: mintty.exe --hold always sh.exe -c "tty > 1.txt; read;" & konsole --no-close sh -e "tty > 1.txt; read;" & gnome-terminal --hold sh -e "tty > 1.txt; read;" & gdb --tty=$(cat 1.txt) emacs run But there is a problem that emacs can't get input from the terminal, because of the read command. The 'read' is unnecessary. Try: konsole --hold -e 'sh -c /usr/bin/tty > konstty' (in konsole, --hold and --noclose are synonyms) and then: gdb --tty $(cat konstty) --args emacs -nw At the gdb prompt type "run" and you should be set to go. Sorry, that should have been: konsole --hold -e 'sh -c "/usr/bin/tty > konstty"' (In reply to ninjalj from comment #7) > Sorry, that should have been: > > konsole --hold -e 'sh -c "/usr/bin/tty > konstty"' Have you tried that ? On windows using mintty, this method does not work perfectly. sometimes the program(emacs) does not respond. I'm trying this with 'mintty -Rt -h alw sleep 99999 &' and running gdb with another screen program (text editor mined) and see no problems.

With this method, you will need to wait for konsole/mintty to open the pty pair and execute 'sh -c "/usr/bin/tty > konstty"'. E.g: you could remove the "konstty" file, and wait for it to have a valid terminal name. On my testing, I have not seen any problem debugging emacs.
