<h4 class="subsection">2.1.3 What <small>GDB</small> Does During Startup</h4>
|
|
<a name="index-GDB-startup"></a>
|
|
|
|
<p>Here’s the description of what <small>GDB</small> does during session startup:
|
|
</p>
|
|
<ol>
|
|
<li> Performs minimal setup required to initialize basic internal state.
|
|
|
|
</li><li> <a name="index-early-initialization-file"></a>
|
|
Reads commands from the early initialization file (if any) in your
|
|
home directory. Only a restricted set of commands can be placed into
|
|
an early initialization file, see <a href="Initialization-Files.html#Initialization-Files">Initialization Files</a>, for
|
|
details.
|
|
|
|
</li><li> Executes commands and command files specified by the ‘<samp>-eiex</samp>’ and
|
|
‘<samp>-eix</samp>’ command line options in their specified order. Only a
|
|
restricted set of commands can be used with ‘<samp>-eiex</samp>’ and
|
|
‘<samp>eix</samp>’, see <a href="Initialization-Files.html#Initialization-Files">Initialization Files</a>, for details.
|
|
|
|
</li><li> Sets up the command interpreter as specified by the command line
|
|
(see <a href="Mode-Options.html#Mode-Options">interpreter</a>).
|
|
|
|
</li><li> <a name="index-init-file"></a>
|
|
Reads the system wide initialization file and the files from the
|
|
system wide initialization directory, see <a href="Initialization-Files.html#System-Wide-Init-Files">System Wide Init Files</a>.
|
|
|
|
</li><li> Reads the initialization file (if any) in your home directory and
|
|
executes all the commands in that file, see <a href="Initialization-Files.html#Home-Directory-Init-File">Home Directory Init File</a>.
|
|
|
|
<a name="Option-_002dinit_002deval_002dcommand"></a></li><li> Executes commands and command files specified by the ‘<samp>-iex</samp>’ and
|
|
‘<samp>-ix</samp>’ options in their specified order. Usually you should use the
|
|
‘<samp>-ex</samp>’ and ‘<samp>-x</samp>’ options instead, but this way you can apply
|
|
settings before <small>GDB</small> init files get executed and before inferior
|
|
gets loaded.
|
|
|
|
</li><li> Processes command line options and operands.
|
|
|
|
</li><li> Reads and executes the commands from the initialization file (if any)
|
|
in the current working directory as long as ‘<samp>set auto-load
|
|
local-gdbinit</samp>’ is set to ‘<samp>on</samp>’ (see <a href="Init-File-in-the-Current-Directory.html#Init-File-in-the-Current-Directory">Init File in the Current Directory</a>). This is only done if the current directory is different
|
|
from your home directory. Thus, you can have more than one init file,
|
|
one generic in your home directory, and another, specific to the
|
|
program you are debugging, in the directory where you invoke
|
|
<small>GDB</small>. See <a href="Initialization-Files.html#Init-File-in-the-Current-Directory-during-Startup">Init File in the Current Directory during Startup</a>.
|
|
|
|
</li><li> If the command line specified a program to debug, or a process to
|
|
attach to, or a core file, <small>GDB</small> loads any auto-loaded
|
|
scripts provided for the program or for its loaded shared libraries.
|
|
See <a href="Auto_002dloading.html#Auto_002dloading">Auto-loading</a>.
|
|
|
|
<p>If you wish to disable the auto-loading during startup,
|
|
you must do something like the following:
|
|
</p>
|
|
<div class="smallexample">
|
|
<pre class="smallexample">$ gdb -iex "set auto-load python-scripts off" myprogram
|
|
</pre></div>
|
|
|
|
<p>Option ‘<samp>-ex</samp>’ does not work because the auto-loading is then turned
|
|
off too late.
|
|
</p>
|
|
</li><li> Executes commands and command files specified by the ‘<samp>-ex</samp>’ and
|
|
‘<samp>-x</samp>’ options in their specified order. See <a href="Command-Files.html#Command-Files">Command Files</a>, for
|
|
more details about <small>GDB</small> command files.
|
|
|
|
</li><li> Reads the command history recorded in the <em>history file</em>.
|
|
See <a href="Command-History.html#Command-History">Command History</a>, for more details about the command history and the
|
|
files where <small>GDB</small> records it.
|
|
</li></ol>
