I've been holding back on this because 1.7.0 requires OpenSSL 1.1.0 or newer for full DANE support. But we can't wait forever, and nothing in base uses DANE anyway, so here we go.

# 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 ...
