In other projects, it is set to# `$srcdir', `$srcdir/..', or `$srcdir/../..'.## Of course, Automake must honor this variable whenever it calls a# tool from the auxiliary directory. The problem is that $srcdir (and# therefore $ac_aux_dir as well) can be either absolute or relative,# depending on how configure is run. This is pretty annoying, since# it makes $ac_aux_dir quite unusable in subdirectories: in the top# source directory, any form will work fine, but in subdirectories a# relative path needs to be adjusted first.## $ac_aux_dir/missing# fails when called from a subdirectory if $ac_aux_dir is relative# $top_srcdir/$ac_aux_dir/missing# fails if $ac_aux_dir is absolute,# fails when called from a subdirectory in a VPATH build with# a relative $ac_aux_dir## The reason of the latter failure is that $top_srcdir and $ac_aux_dir# are both prefixed by $srcdir. In an in-source build this is usually# harmless because $srcdir is `.', but things will broke when you# start a VPATH build or use an absolute $srcdir.## So we could use something similar to $top_srcdir/$ac_aux_dir/missing,# iff we strip the leading $srcdir from $ac_aux_dir. That would be:# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`# and then we would define $MISSING as# MISSING="\${SHELL} $am_aux_dir/missing"# This will work as long as MISSING is not called from configure, because# unfortunately $(top_srcdir) has no meaning in configure.# However there are other variables, like CC, which are often used in# configure, and could therefore not use this "fixed" $ac_aux_dir.## Another solution, used here, is to always expand $ac_aux_dir to an# absolute PATH. The drawback is that using absolute paths prevent a# configured tree to be moved without reconfiguration.# Rely on autoconf to set up CDPATH properly.AC_PREREQ([2.50])AC_DEFUN([AM_AUX_DIR_EXPAND], [# expand $ac_aux_dir to an absolute patham_aux_dir=`cd $ac_aux_dir && pwd`])# AM_PROG_INSTALL_SH# ------------------# Define $install_sh.# Copyright 2001 Free Software Foundation, Inc.# This program is free software; you can redistribute it and/or modify# it under the terms of the GNU General Public License as published by# the Free Software Foundation; either version 2, or (at your option)# any later version.# This program is distributed in the hope that it will be useful,# but WITHOUT ANY WARRANTY; without even the implied warranty of# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
