AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
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.
