Simple utility for setting configuration values from the command line.
|
||
|
|
|
||
|
|
Sample usage:
|
||
|
|
|
||
|
|
$ setconfig FOO_SUPPORT=y BAR_BITS=8
|
||
|
|
|
||
|
|
Note: Symbol names should not be prefixed with 'CONFIG_'.
|
||
|
|
|
||
|
|
The exit status on errors is 1.
|
||
|
|
|
||
|
|
The default input/output configuration file is '.config'. A different filename
|
||
|
|
can be passed in the KCONFIG_CONFIG environment variable.
