Packit c06654
#
Packit c06654
# Of course, Automake must honor this variable whenever it calls a
Packit c06654
# tool from the auxiliary directory.  The problem is that $srcdir (and
Packit c06654
# therefore $ac_aux_dir as well) can be either absolute or relative,
Packit c06654
# depending on how configure is run.  This is pretty annoying, since
Packit c06654
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
Packit c06654
# source directory, any form will work fine, but in subdirectories a
Packit c06654
# relative path needs to be adjusted first.
Packit c06654
#
Packit c06654
# $ac_aux_dir/missing
Packit c06654
#    fails when called from a subdirectory if $ac_aux_dir is relative
Packit c06654
# $top_srcdir/$ac_aux_dir/missing
Packit c06654
#    fails if $ac_aux_dir is absolute,
Packit c06654
#    fails when called from a subdirectory in a VPATH build with
Packit c06654
#          a relative $ac_aux_dir
Packit c06654
#
Packit c06654
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
Packit c06654
# are both prefixed by $srcdir.  In an in-source build this is usually
Packit c06654
# harmless because $srcdir is '.', but things will broke when you
Packit c06654
# start a VPATH build or use an absolute $srcdir.
Packit c06654
#
Packit c06654
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
Packit c06654
# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
Packit c06654
#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
Packit c06654
# and then we would define $MISSING as
Packit c06654
#   MISSING="\${SHELL} $am_aux_dir/missing"
Packit c06654
# This will work as long as MISSING is not called from configure, because
Packit c06654
# unfortunately $(top_srcdir) has no meaning in configure.
Packit c06654
# However there are other variables, like CC, which are often used in
Packit c06654
# configure, and could therefore not use this "fixed" $ac_aux_dir.
Packit c06654
#
Packit c06654
# Another solution, used here, is to always expand $ac_aux_dir to an
Packit c06654
