This feature is currently present only on <span class="sc">gnu</span>/Linux native hosts.
|
||
|
|
|
||
|
|
<p><span class="sc">gdb</span> reads in some cases thread debugging library from places specific
|
||
|
|
to the inferior (see <a href="set-libthread_002ddb_002dsearch_002dpath.html#set-libthread_002ddb_002dsearch_002dpath">set libthread-db-search-path</a>).
|
||
|
|
|
||
|
|
<p>The special ‘<samp><span class="samp">libthread-db-search-path</span></samp>’ entry ‘<samp><span class="samp">$sdir</span></samp>’ is processed
|
||
|
|
without checking this ‘<samp><span class="samp">set auto-load libthread-db</span></samp>’ switch as system
|
||
|
|
libraries have to be trusted in general. In all other cases of
|
||
|
|
‘<samp><span class="samp">libthread-db-search-path</span></samp>’ entries <span class="sc">gdb</span> checks first if ‘<samp><span class="samp">set
|
||
|
|
auto-load libthread-db</span></samp>’ is enabled before trying to open such thread debugging
|
||
|
|
library.
|
||
|
|
|
||
|
|
<p>Note that loading of this debugging library also requires accordingly configured
|
||
|
|
<code>auto-load safe-path</code> (see <a href="Auto_002dloading-safe-path.html#Auto_002dloading-safe-path">Auto-loading safe path</a>).
