# SYNOPSIS
|
||
|
#
|
||
|
# AX_CONFIG_FEATURE(FEATURE-NAME, FEATURE-DESCRIPTION, DEFINE, DEFINE-DESCRIPTION, [ACTION-IF-ENABLED [, ACTION-IF-NOT-ENABLED]])
|
||
|
#
|
||
|
# DESCRIPTION
|
||
|
#
|
||
|
# AX_CONFIG_FEATURE is a simple wrapper for AC_ARG_ENABLE, it enables the
|
||
|
# feature FEATURE-NAME and AC_DEFINEs the passed DEFINE, depending on the
|
||
|
# user choice. DESCRIPTION will be used for AC_DEFINEs. ACTION-IF-ENABLED
|
||
|
# and ACTION-IF-NOT-ENABLED are the actions that will be run. A feature is
|
||
|
# enabled by default, in order to change this behaviour use the
|
||
|
# AX_CONFIG_FEATURE_DEFAULT_ENABLED and AX_CONFIG_FEATURE_DEFAULT_DISABLED
|
||
|
# macros.
|
||
|
#
|
||
|
# A simple example:
|
||
|
#
|
||
|
# AX_CONFIG_FEATURE_DEFAULT_ENABLED
|
||
|
# AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support],
|
||
|
# HAVE_XXXXX, [Define if you want XXXXX support])
|
||
|
#
|
||
|
# ...
|
||
|
#
|
||
|
# AX_CONFIG_FEATURE_DEFAULT_DISABLED
|
||
|
# AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support],
|
||
|
# HAVE_YYYYY, [Define if you want YYYYY support],
|
||
|
# [enable_yyyyy="yes"], [enable_yyyyy="no"])
|
||
|
# AM_CONDITIONAL(YYYYY, [test "$enable_yyyyy" = "yes"])
|
||
|
#
|
||
|
# AX_CONFIG_FEATURE_DEFAULT_ENABLED
|
||
|
# AX_CONFIG_FEATURE(...)
|
||
|
#
|
||
|
# ...
|
||
|
#
|
||
|
# If you have lot of features and you want a verbose dumping of each user
|
||
|
# selection use AX_CONFIG_FEATURE_VERBOSE. Use AX_CONFIG_FEATURE_SILENT in
|
||
|
# order to remove a previously AX_CONFIG_FEATURE_VERBOSE. By default
|
||
|
# features are silent.
|
||
|
#
|
||
|
# Use AX_CONFIG_FEATURE_ENABLE or AX_CONFIG_FEATURE_DISABLE in order to
|
||
|
# enable or disable a specific feature.
|
||
|
#
|
||
|
# Another simple example:
|
||
|
#
|
||
|
# AS_IF([some_test_here],[AX_CONFIG_FEATURE_ENABLE(feature_xxxxx)],[])
|
||
|
#
|
||
|
# AX_CONFIG_FEATURE(feature_xxxxx, [turns on/off XXXXX support],
|
||
|
# HAVE_XXXXX, [Define if you want XXXXX support])
|
||
|
# AX_CONFIG_FEATURE(feature_yyyyy, [turns on/off YYYYY support],
|
||
|
# HAVE_YYYYY, [Define if you want YYYYY support],
|
||
|
# [enable_yyyyy="yes"], [enable_yyyyy="no"])
|
||
|
#
|
||
|
# ...
|
||
|
#
|
||
|
# NOTE: AX_CONFIG_FEATURE_ENABLE() must be placed first of the relative
|
||
|
# AX_CONFIG_FEATURE() macro ...
