debugging ncurses from emacs

debugging ncurses from emacs

[Hadron Quark]

I am trying to debug an app using the ncurses library using gdba.

I have opened a terminal and queried its tty ID using "tty"

I get something like "/dev/pts/2"

I go back to me debugging session in emacs (gdba) and type

"tty /dev/pts/2"

in order to seperate the programs IO from the gdb output.

But the output from the program being debugged freezes after a few lines.

Any ideas or pointers?

That's because the shell grabs input from the same terminal.  It should
work if you type something like "sleep 10000" in it first.

If your ncurses app is a bit like Emacs and you're not debugging startup, you
can run it in a terminal, find it's process no (1234, say) and attach to it
in gdb with "attach 1234".
