# 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
