# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets | ||||
# $ac_aux_dir to '$srcdir/foo'. 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 | ||||
