# 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
|
||
|
|
# configured tree to be moved without reconfiguration.
