NAME

       kconfig-qconf - Standalone implementation of the Linux Kconfig parser

SYNOPSIS

       kconfig-qconf [options] <KConfig_file>

DESCRIPTION

       The kconfig toolkit support the Kconfig language and implement the parser and the configuration support
       associated to the KConfig files respecting the Linux kernel KConfig convention.

       At configuration time:

       • kconfig-mconf is based on ncurses (menuconfig)

       • kconfig-conf is based on dialog (config)

       • kconfig-gconf is based on GTK+ (gconfig)

       • kconfig-qconf is based on QT (qconfig)

       Associated tools:

       • kconfig-diff displays symbols diff between .config files

OPTIONS

       --silentoldconfig  Only  for kconfig-conf, reload a given .config and regenerate header and command files
       accordingly.

       --allnoconfig Set all boolean configuration to no.

       --allyesconfig Set all boolean configuration to yes.

       --randconfig Generates a random configuration.

ENVIRONMENT

Environment variables for '*config'

       KCONFIG_CONFIG

       This environment variable can be used to specify a default  kernel  config  file  name  to  override  the
       default name of ".config".

       KCONFIG_OVERWRITECONFIG

       If  you set KCONFIG_OVERWRITECONFIG in the environment, Kconfig will not break symlinks when .config is a
       symlink to somewhere else.

       CONFIG_

       If you set CONFIG_ in the environment, Kconfig will prefix all symbols with its  value  when  saving  the
       configuration, instead of using the default, "CONFIG_".

Environment variables for '{allyes/allmod/allno/rand}config'

       KCONFIG_ALLCONFIG

       The  allyesconfig/allmodconfig/allnoconfig/randconfig  variants  can  also  use  the environment variable
       KCONFIG_ALLCONFIG as a flag or a filename that contains config symbols that the user requires to  be  set
       to  a  specific  value.  If KCONFIG_ALLCONFIG is used without a filename where KCONFIG_ALLCONFIG == "" or
       KCONFIG_ALLCONFIG == "1", "make *config" checks  for  a  file  named  "all{yes/mod/no/def/random}.config"
       (corresponding  to  the  *config command that was used) for symbol values that are to be forced.  If this
       file is not found, it checks for a file named "all.config" to contain forced values.

       This enables you to create "miniature" config (miniconfig) or custom config  files  containing  just  the
       config  symbols  that  you  are  interested in.  Then the kernel config system generates the full .config
       file, including symbols of your miniconfig file.

       This 'KCONFIG_ALLCONFIG' file is a config file which contains (usually a subset  of  all)  preset  config
       symbols.  These variable settings are still subject to normal dependency checks.

       Examples:
           KCONFIG_ALLCONFIG=custom-notebook.config make allnoconfig or
           KCONFIG_ALLCONFIG=mini.config make allnoconfig or
           make KCONFIG_ALLCONFIG=mini.config allnoconfig

       These  examples  will  disable  most  options  (allnoconfig)  but  enable or disable the options that are
       explicitly listed in the specified mini-config files.

Environment variables for 'randconfig'

       KCONFIG_SEED

       You can set this to the integer value used to seed the RNG, if you want to somehow debug the behaviour of
       the kconfig parser/frontends.  If not set, the current time will be used.

       KCONFIG_PROBABILITY

       This      variable      can      be      used      to      skew       the       probabilities.        See
       /usr/share/doc/kconfig-frontends/kconfig.txt.gz.

       Environment variables for 'silentoldconfig'

       KCONFIG_NOSILENTUPDATE

       If  this  variable  has  a  non-blank  value, it prevents silent kernel config updates (requires explicit
       updates).

       KCONFIG_AUTOCONFIG

       This environment variable can be set to specify the path  name of  the  "auto.conf"  file.   Its  default
       value is "include/config/auto.conf".

       KCONFIG_TRISTATE

       This  environment variable can be set to specify the path  name of the "tristate.conf" file.  Its default
       value is "include/config/tristate.conf".

       KCONFIG_AUTOHEADER

       This environment variable can be set to specify the path  name of the "autoconf.h"  (header)  file.   Its
       default value is "include/generated/autoconf.h".
