# SYNOPSIS
|
|
#
|
|
# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Check for the presence of an --enable-debug option to configure, with
|
|
# the specified default value used when the option is not present. Return
|
|
# the value in the variable $ax_enable_debug.
|
|
#
|
|
# Specifying 'yes' adds '-g -O0' to the compilation flags for all
|
|
# languages. Specifying 'info' adds '-g' to the compilation flags.
|
|
# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
|
|
# the linking flags. Otherwise, nothing is added.
|
|
#
|
|
# Define the variables listed in the second argument if debug is enabled,
|
|
# defaulting to no variables. Defines the variables listed in the third
|
|
# argument if debug is disabled, defaulting to NDEBUG. All lists of
|
|
# variables should be space-separated.
|
|
#
|
|
# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
|
|
# Should be invoked prior to any AC_PROG_* compiler checks.
|
|
#
|
|
# IS-RELEASE can be used to change the default to 'no' when making a
|
|
# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
|
|
# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
|
|
# macro, there is no need to pass this parameter.
|
|
#
|
|
# AX_IS_RELEASE([git-directory])
|
|
