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.
set data-directory
directoryshow data-directory
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.
