|
||
|
|
<p>A <em>target</em> is the execution environment occupied by your program.
|
||
|
|
</p>
|
||
|
|
<p>Often, <small>GDB</small> runs in the same host environment as your program;
|
||
|
|
in that case, the debugging target is specified as a side effect when
|
||
|
|
you use the <code>file</code> or <code>core</code> commands. When you need more
|
||
|
|
flexibility—for example, running <small>GDB</small> on a physically separate
|
||
|
|
host, or controlling a standalone system over a serial port or a
|
||
|
|
realtime system over a TCP/IP connection—you can use the <code>target</code>
|
||
|
|
command to specify one of the target types configured for <small>GDB</small>
|
||
|
|
(see <a href="Target-Commands.html#Target-Commands">Commands for Managing Targets</a>).
|
||
|
|
</p>
|
||
|
|
<a name="index-target-architecture"></a>
|
||
|
|
<p>It is possible to build <small>GDB</small> for several different <em>target
|
||
|
|
architectures</em>. When <small>GDB</small> is built like that, you can choose
|
||
|
|
one of the available architectures with the <kbd>set architecture</kbd>
|
||
|
|
command.
