gdb will sometimes read an auxiliary data file. These files are kept in a directory known as the data directory.
You can set the data directory's name, and view the name gdb is currently using.
You can set the default data directory by using the configure-time ‘--with-gdb-datadir’ option. If the data directory is inside gdb's configured binary prefix (set with ‘--prefix’ or ‘--exec-prefix’), then the default data directory will be updated automatically if the installed gdb is moved to a new location.
The data directory may also be specified with the
--data-directory command line option.
