In other projects, it is set to 24# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 25# 26# Of course, Automake must honor this variable whenever it calls a 27# tool from the auxiliary directory. The problem is that $srcdir (and 28# therefore $ac_aux_dir as well) can be either absolute or relative, 29# depending on how configure is run. This is pretty annoying, since 30# it makes $ac_aux_dir quite unusable in subdirectories: in the top 31# source directory, any form will work fine, but in subdirectories a 32# relative path needs to be adjusted first. 33# 34# $ac_aux_dir/missing 35# fails when called from a subdirectory if $ac_aux_dir is relative 36# $top_srcdir/$ac_aux_dir/missing 37# fails if $ac_aux_dir is absolute, 38# fails when called from a subdirectory in a VPATH build with 39# a relative $ac_aux_dir 40# 41# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 42# are both prefixed by $srcdir. In an in-source build this is usually 43# harmless because $srcdir is `.', but things will broke when you 44# start a VPATH build or use an absolute $srcdir. 45# 46# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 47# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 48# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 49# and then we would define $MISSING as 50# MISSING="\${SHELL} $am_aux_dir/missing" 51# This will work as long as MISSING is not called from configure, because 52# unfortunately $(top_srcdir) has no meaning in configure. 53# However there are other variables, like CC, which are often used in 54# configure, and could therefore not use this "fixed" $ac_aux_dir. 55# 56# Another solution, used here, is to always expand $ac_aux_dir to an 57# absolute PATH. The drawback is that using absolute paths prevent a 58# configured tree to be moved without reconfiguration. 59 60AC_DEFUN([AM_AUX_DIR_EXPAND], 61[dnl Rely on autoconf to set up CDPATH properly. 62AC_PREREQ([2.50])dnl 63# expand $ac_aux_dir to an absolute path 64am_aux_dir=`cd $ac_aux_dir && pwd` 65]) 66 67# AM_CONDITIONAL -*- Autoconf -*- 68 69# Copyright (C) 1997, 2000, 2001, 2003, 2004, 2005, 2006, 2008 70# Free Software Foundation, Inc. 71# 72# This file is free software; the Free Software Foundation 73# gives unlimited permission to copy and/or distribute it, 74# with or without modifications, as long as this notice is preserved. 75 76# serial 9 77 78# AM_CONDITIONAL(NAME, SHELL-CONDITION) 79# ------------------------------------- 80# Define a conditional. 81AC_DEFUN([AM_CONDITIONAL], 82[AC_PREREQ(2.52)dnl 83 ifelse([$1], [TRUE], [AC_FATAL([$0: invalid condition: $1])], 84 [$1], [FALSE], [AC_FATAL([$0: invalid condition: $1])])dnl 85AC_SUBST([$1_TRUE])dnl 86AC_SUBST([$1_FALSE])dnl 87_AM_SUBST_NOTMAKE([$1_TRUE])dnl 88_AM_SUBST_NOTMAKE([$1_FALSE])dnl 89m4_define([_AM_COND_VALUE_$1], [$2])dnl 90if $2; then 91 $1_TRUE= 92 $1_FALSE='#' 93else 94 $1_TRUE='#' 95 $1_FALSE= 96fi 97AC_CONFIG_COMMANDS_PRE( 98[if test -z "${$1_TRUE}" && test -z "${$1_FALSE}"; then 99 AC_MSG_ERROR([[conditional "$1" was never defined. 100Usually this means the macro was only invoked conditionally.]]) 101fi])]) 102 103# Add --enable-maintainer-mode option to configure. -*- Autoconf -*- 104# From Jim Meyering 105 106# Copyright (C) 1996, 1998, 2000, 2001, 2002, 2003, 2004, 2005, 2008 107# Free Software Foundation, Inc. 108# 109# This file is free software; the Free Software Foundation 110# gives unlimited permission to copy and/or distribute it, 111# with or without modifications, as long as this notice is preserved. 112 113# serial 5 114 115# AM_MAINTAINER_MODE([DEFAULT-MODE]) 116# ---------------------------------- 117# Control maintainer-specific portions of Makefiles. 118# Default is to disable them, unless `enable' is passed literally. 119# For symmetry, `disable' may be passed as well.
