##### 23.2.3.1 The `objfile-gdb.py` file

When a new object file is read, gdb looks for a file named `objfile-gdb.py` (we call it script-name below), where objfile is the object file's real name, formed by ensuring that the file name is absolute, following all symlinks, and resolving `.` and `..` components. If this file exists and is readable, gdb will evaluate it as a Python script.

If this file does not exist, then gdb will look for script-name file in all of the directories as specified below.

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

`set auto-load scripts-directory` [directories]
  Control gdb auto-loaded scripts location. Multiple directory entries may be delimited by the host platform path separator in use (‘`:`’ on Unix, ‘`;`’ on MS-Windows and MS-DOS).

  Each entry here needs to be covered also by the security setting `set auto-load safe-path` (see set auto-load safe-path).

  This variable defaults to `$debugdir:$datadir/auto-load`. The default `set auto-load safe-path` value can be also overriden by gdb configuration option `--with-auto-load-dir`.

  Any reference to `$debugdir` will get replaced by debug-file-directory value (see Separate Debug Files) and any reference to `$datadir` will get replaced by data-directory which is determined at gdb startup (see Data Files). `$debugdir` and `$datadir` must be placed as a directory component — either alone or delimited by `/` or `\` directory separators, depending on the host platform.

  The list of directories uses path separator (‘`:`’ on GNU and Unix systems, ‘`;`’ on MS-Windows and MS-DOS) to separate directories, similarly to the `PATH` environment variable.

`show auto-load scripts-directory`
  Show gdb auto-loaded scripts location.

gdb does not track which files it has already auto-loaded this way. gdb will load the associated script every time the corresponding objfile is opened. So your `-gdb.py` file should be careful to avoid errors if it is evaluated more than once.
