gdb starts GDB in a graphical interface, using
Emacs windows for display program state information. With it, you do
not need to use textual GDB commands; you can control the debugging
session with the mouse. For example, you can click in the fringe of a
source buffer to set a breakpoint there, or on a stack frame in the
stack buffer to select that frame.
This mode requires telling GDB that its “screen size” is unlimited, so it sets the height and width accordingly. For correct operation you must not change these values during the GDB session.
To run GDB in text command mode, like the other debuggers in Emacs, use M-x gud-gdb. You need to use text command mode to debug multiple programs within one Emacs session.blog comments powered by Disqus
