In other projects, it is set to 43# `$srcdir', `$srcdir/..', or `$srcdir/../..'. 44# 45# Of course, Automake must honor this variable whenever it calls a 46# tool from the auxiliary directory. The problem is that $srcdir (and 47# therefore $ac_aux_dir as well) can be either absolute or relative, 48# depending on how configure is run. This is pretty annoying, since 49# it makes $ac_aux_dir quite unusable in subdirectories: in the top 50# source directory, any form will work fine, but in subdirectories a 51# relative path needs to be adjusted first. 52# 53# $ac_aux_dir/missing 54# fails when called from a subdirectory if $ac_aux_dir is relative 55# $top_srcdir/$ac_aux_dir/missing 56# fails if $ac_aux_dir is absolute, 57# fails when called from a subdirectory in a VPATH build with 58# a relative $ac_aux_dir 59# 60# The reason of the latter failure is that $top_srcdir and $ac_aux_dir 61# are both prefixed by $srcdir. In an in-source build this is usually 62# harmless because $srcdir is `.', but things will broke when you 63# start a VPATH build or use an absolute $srcdir. 64# 65# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, 66# iff we strip the leading $srcdir from $ac_aux_dir. That would be: 67# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` 68# and then we would define $MISSING as 69# MISSING="\${SHELL} $am_aux_dir/missing" 70# This will work as long as MISSING is not called from configure, because 71# unfortunately $(top_srcdir) has no meaning in configure. 72# However there are other variables, like CC, which are often used in 73# configure, and could therefore not use this "fixed" $ac_aux_dir. 74# 75# Another solution, used here, is to always expand $ac_aux_dir to an 76# absolute PATH. The drawback is that using absolute paths prevent a 77# configured tree to be moved without reconfiguration. 78 79AC_DEFUN([AM_AUX_DIR_EXPAND], 80[dnl Rely on autoconf to set up CDPATH properly. 81AC_PREREQ([2.50])dnl 82# expand $ac_aux_dir to an absolute path 83am_aux_dir=`cd $ac_aux_dir && pwd` 84]) 85 86# AM_CONDITIONAL -*- Autoconf -*- 87 88# Copyright (C) 1997, 2000, 2001, 2003, 2004, 2005 89# Free Software Foundation, Inc. 90# 91# This file is free software; the Free Software Foundation 92# gives unlimited permission to copy and/or distribute it, 93# with or without modifications, as long as this notice is preserved. 94 95# serial 7 96 97# AM_CONDITIONAL(NAME, SHELL-CONDITION) 98# ------------------------------------- 99# Define a conditional. 100AC_DEFUN([AM_CONDITIONAL], 101[AC_PREREQ(2.52)dnl 102 ifelse([$1], [TRUE], [AC_FATAL([$0: invalid condition: $1])], 103 [$1], [FALSE], [AC_FATAL([$0: invalid condition: $1])])dnl 104AC_SUBST([$1_TRUE]) 105AC_SUBST([$1_FALSE]) 106if $2; then 107 $1_TRUE= 108 $1_FALSE='#' 109else 110 $1_TRUE='#' 111 $1_FALSE= 112fi 113AC_CONFIG_COMMANDS_PRE( 114[if test -z "${$1_TRUE}" && test -z "${$1_FALSE}"; then 115 AC_MSG_ERROR([[conditional "$1" was never defined. 116Usually this means the macro was only invoked conditionally.]]) 117fi])]) 118 119 120# Copyright (C) 1999, 2000, 2001, 2002, 2003, 2004, 2005 121# Free Software Foundation, Inc. 122# 123# This file is free software; the Free Software Foundation 124# gives unlimited permission to copy and/or distribute it, 125# with or without modifications, as long as this notice is preserved. 126 127# serial 8 128 129# There are a few dirty hacks below to avoid letting `AC_PROG_CC' be 130# written in clear, in which case automake, when reading aclocal.m4, 131# will think it sees a *use*, and therefore will trigger all it's 132# C support machinery.
