[STUMP] tty redirection from GDB to xterm not working

[Carlos Konstanski]

I am running an ncurses C++ program under GDB from within Emacs for a
programming assignment at school. I use the following trick to get the
console output redirected to an xterm so that the ncurses stuff works:

http://cdw.sourceforge.net/documentation/emacs_gdb_ncurses/emacs_gdb_ncurses.en.html#cleaning_upa

The problem is that I have to log into an xfce4 desktop environment to get
this to work. If I try it from stumpwm, I get the following message in the
xterm when GDB tries to send output to it:

warning: GDB: Failed to set controlling terminal: Operation not permitted

All things are equal except that in one case I am running xfce4, and in the
other case I am running stumpwm. I am running stumpwm from the saved image
that is built by the makefile, and I am using SBCL.

Any ideas how I can get past this problem?

Thanks,
