- Synopsis
AC_COND_WITH_LEVEL(PACKAGE [,DEFAULT [,YESLEVEL]])- Version
1.1.1.1 (2001/07/26) Miscellaneous @ ac-archive-0.5.39
- Author
Guido Draheim <guidod@gmx.de>
- 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)
