ax_cond_with_level

Synopsis

AX_COND_WITH_LEVEL(PACKAGE [,DEFAULT [,YESLEVEL]])

Description

Actually used after an AC_ARG_WITH(PKG,...) option-directive, where AC_ARG_WITH is a part of the standard autoconf to define a ‘configure‘ –with-PKG option.

This macros works almost like AC_COND_WITH(PACKAGE [,DEFAULT]), but the definition is set to a numeric value. The level of a simple "yes" is given (or assumed "2" if absent), otherwise the level can be given in mnemonic names, being:

 1 = some
 2 = many
 3 = all
 4 = extra
 5 = extrasome more
 6 = extramany muchmore much
 7 = super everything
 8 = ultra experimental
 9 = insane

this macro is most handily it making Makefile.in/Makefile.am that have a set of with-level declarations, espcially optimization-levels

the $withval shell-variable is set for further examination (it carries the numeric value of the various mnemonics above)
