|
|
|
This file describes a graphical interface to @value{GDBN},
|
|
the GNU symbolic debugger.
|
|
|
|
@node Invocation
|
|
@chapter Starting up GUI @value{GDBN}
|
|
|
|
If @value{GDBN} has been configured to use the graphical interface,
|
|
then you will get the interface automatically upon startup.
|
|
|
|
When running as a Unix program and using the X11-based interface,
|
|
you must of course be using an X server and/or workstation,
|
|
and your @code{DISPLAY} environment variable must be set correctly.
|
|
If either of these is not true, then @value{GDBN} will still start up,
|
|
but will use only the traditional command interface.
|
|
|
|
The exact layout and appearance of the windows will depend on the host
|
|
system type. For instance, GDB under Windows will display its windows
|
|
inside a larger window, while under Unix/X, each window is a separate
|
|
toplevel window. However, general behavior and layout is consistent
|
|
across all platforms; omissions or restrictions on particular platforms,
|
|
if not documented as unavoidable, should be considered bugs and
|
|
reported.
|
|
|
|
All GDB windows have a common structure. Each window has an associated
|
|
menu bar, which may be at the top of the window or perhaps elsewhere.
|
|
Some of the menus and menu items in the menu bar are common to all GDB
|
|
windows, while others are specific to particular types of windows.
|
|
Below the menu bar is the working data area of the window. If the data
|
|
is too large to display all at once, the data area will have scroll bars
|
|
on its right and bottom sides. Below the data area are two optional
|
|
features; a status/data line, and a button box.
|
|
|
|
@section Menus
|
|
|
|
@subsection File Menu
|
|
|
|
The standard file menu provides operations that affect the overall state
|
|
of GDB, mainly file operations, but other things as well.
|
|
|
|
About GDB...
|
|
|
|
Displays the startup window for GDB.
|
|
|
|
File...
|
|
|
|
Lets you set the combined executable and symbol file that GDB will use.
|
|
(Like "file".)
|
|
|
|
Target...
|
|
|
|
Brings up a dialog that you can use to connect GDB to a target program.
|
|
The dialog is described in more depth later.
|
|
(Like "target".)
|
|
|
|
Edit...
|
|
|
|
Starts up an editor to modify the source file being displayed.
|
|
|
|
Exec File...
|
|
|
|
Lets you set the executable file that GDB will use.
|
|
(Like "exec-file".)
|
|
|
|
Symbol File...
|
|
|
|
Lets you set the symbol file that GDB will use.
|
|
(Like "symbol-file".)
|
|
|
|
Add Symbol File...
|
|
|
|
Lets you add additional symbol files.
|
|
(Like "add-symbol-file".)
|
|
|
|
Core File...
|
|
|
|
Lets you set the core file that GDB will use.
|
|
(Like "core-file".)
|
|
|
|
Shared Libraries...
|
|
|
|
(Like "sharedlibrary".)
|
|
|
|
Quit
|
|
|
|
quits GDB.
|
|
(Like @samp{quit}.)
|
|
|
|
|
|
@c @subsection Commands Menu
|
|
|
|
@c The commands menu consists of items that let you run and control the program being
|
|
@c debugged.
|
|
@c
|
|
@c Run
|
|
@c
|
|
@c Step
|
|
@c
|
|
@c Next
|
|
@c
|
|
@c Finish
|
|
@c
|
|
@c Stepi
|
|
@c
|
|
@c Nexti
|
|
|
|
@subsection Windows Menu
|
|
|
|
The windows menu allows access to all the windows available in GDB.
|
|
The first part of the menu lists all of the predefined individual windows.
|
|
If the window exists already, its item will be marked as such;
|
|
selecting the item will cause the window to be put in front if it is
|
|
obscured. If it does not exist, then it will be created.
|
|
|
|
The second part of the menu lists additional windows that you may have
|
|
created, such as source windows or variable displays.
|
|
|
|

|
|
|
|
@subsection View Menu
|
|
|
|
All windows have a view menu, but its contents are highly specific to
|
|
window type. For instance, a source window will have a view menu item
|
|
to control the display of line numbers, but a register window will instead
|
|
have an option to choose the radix in which to display register contents.
|
|
You can find the full description of view options with each window type.
|
|
|
|
@subsection Help Menu
|
|
|
|
The help menu includes access to GDB's online help.
|
|
|
|
@section Windows
|
|
|
|
@subsection Command Window
|
|
|
|
The command window provides access to the standard GDB command
|
|
interpreter. In nearly all cases, commands typed into this window
|
|
will behave exactly as for a non-windowing GDB.
|
|
|
|
Note that not all changes to GDB will be reflected in this window. For instance,
|
|
if you were to type a "step" command, then click on the "step" menu item in
|
|
the source window, then go back, and type another "step" command, the command
|
|
buffer will only show two steps, when you have actually done three. GDB will
|
|
put a "..." into the command buffer when operations in other windows are done,
|
|
as a reminder that the command buffer is incomplete.
|
|
|
|
@c Also note that as a side effect of having the interface and possibly an
|
|
@c associated scripting language built in, additional commands may be
|
|
@c available. For instance, if tcl is in GDB, the command ``tcl <tcl code>''
|
|
@c will be available.
|
|
|
|
The command window has no status line or button box.
|
|
|
|
@subsection Files Window
|
|
|
|
The files window lists all of the files that were used to build the
|
|
executable.
|
|
|
|
Clicking on the xxx in the left margin expands/contracts the display of
|
|
included files and symbols defined by the file.
|
|
|
|
The View menu for this window includes the following items:
|
|
Name/Full Pathname
|
|
@c Sort by Name
|
|
@c Sort by Section&Offset
|
|
@c Show All Included Files
|
|
@c Included File Indentation...
|
|
|
|
@subsection Source Window
|
|
|
|
A source window displays a single file of source code.
|
|
|
|
The left margin includes an indicator for the current PC, breakpoints and potential breakpoints,
|
|
and (optionally) line numbers.
|
|
|
|
The View menu for this window includes the following items:
|
|
Show Line Numbers
|
|
Show Breakdots
|
|
@c Jump to PC (if pc changes, scroll back so PC is centered)
|
|
@c Tab... (set tabbing)
|
|

@c GDBTK Interface Design
|
|
@c
|
|
@c This is the working document describing the design of the GDBTK
|
|
@c interface. Note that overall layout applies only to the default setup;
|
|
@c it is expected that debugger users will be able to customize extensively.
|
|
@c
|
|
@c Default Startup
|
|
@c
|
|
@c One source window, shows source as in "list main", does *not* set a
|
|
@c break at main or run or anything. No current PC indicator, only put
|
|
@c in when something runs.
|
|
@c
|
|
@c Source Window
|
|
@c
|
|
@c For native, "run" button is always the same, for cross, it's actually
|
|
@c a "target" button that pops up appropriate dialog to get connected.
|
|
@c Once remote target is active, change button to "run".
|
|
@c
|
|
@c Be able to toggle assembly interleaved between source.
|
|
@c
|
|
@c Command Window
|
|
@c
|
|
@c Is an *optional* window.
|
|
@c
|
|
@c Behavior mimics command-line GDB running in an Emacs buffer as much
|
|
@c as possible.
|
|
@c
|
|
@c Assembly Window
|
|
@c
|
|
@c Be able to toggle source interleaved between assembly.
|
|
@c
|
|
@c Target Info Window
|
|
@c
|
|
@c Contents similar to "info target".
|
|
@c
|
|
@c Should expand into process and thread info also.
|
|
@c
|
|
@c File Info Window
|
|
@c
|
|
@c Contents similar to "info files".
|
|
@c
|
|
@c Include data shown in "info sources" as well as "info files".
|
|
@c
|
|
@c Register Info Window
|
|
@c
|
|
@c Contents similar to "info registers".
|
|
@c
|
|
@c Add view option(s) for classes of registers.
|
|
@c
|
|
@c Stack Info Window
|
|
@c
|
|
@c Combines backtrace, frame, and local var displays.
|
|
@c
|
|
@c Signals Dialog
|
|
@c
|
|
@c Includes all signals whose handling may be controlled, plus
|
|
@c checkboxes for what to do with each.
|
|
@c
|
|
@c Settings Dialog(s)
|
|
@c
|
|
@c Include all variables that can be "set" and "show"n.
|
|
@c
|
|
@c General Principles
|
|
@c
|
|
@c All windows should have a menu that allows access to other windows.
|
|
@c Selection of item either brings up for first time or brings to front.
|
|
@c
|
|
@c All windows should have a "view" menu that controls formatting
|
|
@c options for that window.
|
|
@c
|
|
@c Windows should usually be scrollable. Windows that display largish
|
|
@c horizontal things should be horizontal and vertical scrollbars.
|
|
@c
|
|
@c To do standard modification, add commands or tcl code to .gdbtkinit.
|
|
@c
|
|
@c Be able to record window positions so they come up in the same way
|
|
@c the next time. Could scribble on .gdbtkinit perhaps, or else an
|
|
@c aux file that can be sourced by .gdbtkinit.
|
|
|
|
@section How to Build
|
|
|
|
If GDB is configured with --enable-gdbtk, then upon startup, it will
|
|
open windows.
