7.2 Starting CrossWind
There are two ways to start a debugging session:
■
From the launcher: Select the desired target and press the button.
■
From the UNIX command line: Invoke crosswind, specifying the target
architecture with the -t option as in the following example.
% crosswind -t sparc &
If you start the debugger from the command line, you must still select a target.
You can either use the Targets menu (see CrossWind Menus, p.238 for details) or
the target wtx command (see Managing Targets, p.257).
7.3 A Sketch of CrossWind
Figure 7-1 illustrates the layout of the main debugger window. This section
discusses each part of the window briefly. The following sections provide more
detail.
The menu bar ➊ provides access to overall control facilities: the File menu lets you
load application modules, or exit; the Targets menu provides a quick way to switch
tasks or targets; the Source menu lets you choose among source-code display
formats; the Tcl menu re-initializes the graphical front end after any customization
to its Tcl definitions; and the Windows menu controls the display of auxiliary
debugger windows. For detailed descriptions of these menus, see CrossWind
Menus, p.238. As usual, the About menu leads to Tornado version information, and
the Help menu leads to the Tornado online manuals.
The buttons ➋ are the quick path to common debugger commands. Most of them
are grouped into related pairs. Table 7-1 shows a summary of each button’s
purpose. For more detailed descriptions of these buttons, see CrossWind Buttons,
p.244.
The program-display panel ➌ is empty when the debugger begins executing. The
debugger automatically displays the current context here, whenever a command
or an event sets the context. In the case of Figure 7-1, the display is the effect of the
list command, often a useful way to start. Once there is a display in the programdisplay
panel, you can select symbols or lines inside that display to serve as
arguments to the button bar in area ➋.
