| <a name="index-system_002dwide-init-file"></a> |
| |
| <p><small>GDB</small> can be configured to have a system-wide init file; |
| this file will be read and executed at startup (see <a href="Startup.html#Startup">What |
| <small>GDB</small> does during startup</a>). |
| </p> |
| <p>Here is the corresponding configure option: |
| </p> |
| <dl compact="compact"> |
| <dt><code>--with-system-gdbinit=<var>file</var></code></dt> |
| <dd><p>Specify that the default location of the system-wide init file is |
| <var>file</var>. |
| </p></dd> |
| </dl> |
| |
| <p>If <small>GDB</small> has been configured with the option <samp>--prefix=$prefix</samp>, |
| it may be subject to relocation. Two possible cases: |
| </p> |
| <ul> |
| <li> If the default location of this init file contains <samp>$prefix</samp>, |
| it will be subject to relocation. Suppose that the configure options |
| are <samp>--prefix=$prefix --with-system-gdbinit=$prefix/etc/gdbinit</samp>; |
| if <small>GDB</small> is moved from <samp>$prefix</samp> to <samp>$install</samp>, the system |
| init file is looked for as <samp>$install/etc/gdbinit</samp> instead of |
| <samp>$prefix/etc/gdbinit</samp>. |
| |
| </li><li> By contrast, if the default location does not contain the prefix, |
| it will not be relocated. E.g. if <small>GDB</small> has been configured with |
| <samp>--prefix=/usr/local --with-system-gdbinit=/usr/share/gdb/gdbinit</samp>, |
| then <small>GDB</small> will always look for <samp>/usr/share/gdb/gdbinit</samp>, |
| wherever <small>GDB</small> is installed. |
| </li></ul> |
| |
| <p>If the configured location of the system-wide init file (as given by the |
| <samp>--with-system-gdbinit</samp> option at configure time) is in the |
| data-directory (as specified by <samp>--with-gdb-datadir</samp> at configure |
| time) or in one of its subdirectories, then <small>GDB</small> will look for the |
| system-wide init file in the directory specified by the |
| <samp>--data-directory</samp> command-line option. |
| Note that the system-wide init file is only read once, during <small>GDB</small> |
| initialization. If the data-directory is changed after <small>GDB</small> has |
| started with the <code>set data-directory</code> command, the file will not be |
| reread. |
