#### 22.7.2 Automatically loading thread debugging library

This feature is currently present only on GNU/Linux native hosts.

GDB reads in some cases thread debugging library from places specific to the inferior (see set libthread-db-search-path).

The special ‘`libthread-db-search-path`’ entry ‘`$sdir`’ is processed without checking this ‘`set auto-load libthread-db`’ switch as system libraries have to be trusted in general. In all other cases of ‘`libthread-db-search-path`’ entries GDB checks first if ‘`set auto-load libthread-db`’ is enabled before trying to open such thread debugging library.

Note that loading of this debugging library also requires accordingly configured `auto-load safe-path` (see Auto-loading safe path).

`set auto-load libthread-db [on|off]`

  Enable or disable the auto-loading of inferior specific thread debugging library.

`show auto-load libthread-db`

  Show whether auto-loading of inferior specific thread debugging library is enabled or disabled.

`info auto-load libthread-db`

  Print the list of all loaded inferior specific thread debugging libraries and for each such library print list of inferior pids using it.
